SDC 432KUR – Frequently Asked Questions

1) What is the difference between the SDC 431, 432, 434 and 435 mushroom button switches?

The difference is contact action and contact arrangement. In the SDC 430 Series: 431C is alternate action on/off, SPST-NC; 431O is alternate action on/off, SPST-NO; 432C is momentary, SPST-NC; 432O is momentary, SPST-NO; 434 is momentary, DPST; 435 is alternate action on/off, DPST; and 432K is momentary latching with key reset, DPST. Momentary means the contact changes state only while the button is held, so it suits a door release. Alternate action latches on and stays until pushed again, which is what you want for an on/off hold or a shunt. DPST gives you two circuits switched together, for example releasing a door and signalling a panel at the same time.

2) Which SDC 430 Series model do I use for an emergency release that has to stay activated until staff reset it?

That is the 432K. It is the momentary latching model with built-in key reset, DPST, so once the button is struck the circuit stays latched until someone with the key restores it. SDC calls out panic alarms and emergency door release as the applications for it. A red button is available on the 432K, which is the usual choice for an emergency station. The alternate action models (431C, 431O, 435) also latch, but anyone can push them back off, so they are not the right pick where you need authorized reset.

3) Will the SDC 430 mushroom switch fit a single gang box?

Yes. The 430 Series plate comes in two sizes, single gang and narrow. Single gang mounts to a standard one gang box. The narrow plate is the one to order when you are mounting to a door frame or a narrow mullion where a single gang plate will not sit flat.

4) If the mushroom button has to carry a legend such as Push to Exit or Emergency Release, what should be used instead of an SDC 430?

The Dortronics 5210 Exit Release, sold as part number DRT5211-MP23, is a 1-9/16 inch diameter red mushroom push button marked Push to Exit and Emergency Release, mounted on a single gang plate. That legend is part of the plate as supplied. The SDC 430 Series device options run B for no sign blank, R for a red button, and LED status indicators in one green, one red, one green and one red, or one tri-color, so the 430 covers status indication rather than printed wording. Both are available on a single gang plate; the 430 Series is offered in narrow and single gang sizes.

5) What is the closest alternative to an SDC 430 mushroom button if the opening needs a red locking mushroom that stays latched until released?

Two paths lead there. Within the 430 Series, the 432K model is momentary latching with key reset, wired DPST, and it is the model the red button option is offered on, so restoration takes a key rather than a second press. If the job calls for a locking mushroom from another maker, the Camden CM-6000 Series is a 2-3/8 inch red locking mushroom switch. The mushroom head sizes differ: the 430 Series uses a 1-1/2 inch round button, the CM-6000 a 2-3/8 inch button, so the faceplate cutout and the visual target size are not the same.

6) Replacing a Dortronics 5210 exit release button on an existing single gang plate with an SDC 430 - what changes?

Three things change. Button diameter goes from the Dortronics 1-9/16 inch to 1-1/2 inch on the 430 Series. The printed legend goes away: the Dortronics DRT5211-MP23 carries Push to Exit and Emergency Release marking, while the 430 Series device options are a blank no-sign plate, a red button, or LED status indication. And the contact arrangement becomes a selection rather than a given, since the 430 Series is ordered by model as SPST-NO, SPST-NC, or DPST and as momentary, alternate action, or key reset latching, so the existing panel wiring dictates which model to pull. Both mount on a single gang plate, and the 430 Series is also offered narrow.

7) How big is the button on the SDC 430 Series mushroom switch?

It is a 1-1/2 inch round mushroom button. That is smaller than some of the other mushroom stations on the market, so if you are matching an existing plate cutout or want a larger strike target, check the diameter before you swap. For comparison, ZenSupply carries the Camden CM-5000 Series at 2-3/8 inches and the Dortronics 5210 exit release at 1-9/16 inches diameter.

8) Can I get an SDC 430 mushroom switch with a status light in the plate?

Yes, the LED indicator is a device option on the 430 Series. Choices are L1G for one green LED, L1R for one red, L2 for one green and one red together, and LT for a single tri-color LED. There is also B for a blank plate with no sign, and R for a red button. Two LEDs (L2) is the common pick when you want to show both locked and unlocked states on the same plate; the tri-color does the same job in one lens.

9) What finishes does the SDC 430 Series push button plate come in, and will it match my other door hardware?

Three finishes: 605 bright brass, 629 bright stainless, and 630 satin stainless steel. 630 satin stainless is the one that matches most commercial door hardware and is the safe pick for standardizing across a facility. 629 bright stainless is the polished version of the same metal, and 605 bright brass matches polished brass trim.

10) What is an alternative to the SDC 432K key reset mushroom switch?

For a locking mushroom station that has to be reset deliberately, the Camden CM-6000 Series is a 2-3/8 inch red locking mushroom switch and is the closest equivalent from another brand ZenSupply carries. The main practical difference is head size, 2-3/8 inches against the SDC's 1-1/2 inch button. If you only need a plain exit release with no latching, the Dortronics 5210 exit release with a 1-9/16 inch red mushroom button on a single gang plate, marked Push to Exit / Emergency Release, is the simpler part.

11) I need one button to release the door and signal the alarm panel at the same time. Which SDC 430 model does that?

Use a DPST model. In the 430 Series that is the 434 (momentary, DPST), the 435 (alternate action on/off, DPST), or the 432K (momentary latching with key reset, DPST). DPST switches two separate circuits from the one button press, so one pole drops the lock and the other reports to the panel. The SPST models (431C, 431O, 432C, 432O) only give you one circuit.

12) What is a simpler substitute for a 430 Series mushroom switch on a plain push-to-exit opening with no latching or contact-arrangement requirement?

The Camden CM-5000 Series is a 2-3/8 inch mushroom pushbutton on an aluminum faceplate, a single straightforward pushbutton without the model-by-model contact choices the 430 Series carries. The 430 Series splits into seven models covering SPST-NO, SPST-NC, DPST, momentary, alternate action, and key reset, which matters when a panel expects a specific arrangement and is extra selection work when it does not. Faceplate material also differs: the CM-5000 is specified with an aluminum faceplate, while the 430 Series is offered in 605 bright brass, 629 bright stainless, and 630 satin stainless steel.

13) Is the Camden CM-AF500 an alternative to an SDC 430 mushroom button switch?

No. The Camden CM-AF500, part of the CX-WC Series, is a single gang LED Occupied When Lit indicator, an annunciator that shows a room state. It is not a switch and does not actuate anything. The SDC 430 Series is a push button switch with heavy duty water resistant contacts in SPST and DPST arrangements. The confusion usually comes from the LED device options on the 430 Series, which add a green, red, dual, or tri-color status indicator to the switch plate. If the design needs both the actuation and a separate occupied annunciator on its own gang, those are two different devices.

14) Which mushroom button has the largest head if the requirement is a big strike target for gloved or emergency use?

Of the comparable mushroom devices, the Camden CM-5000 Series and the Camden CM-6000 Series both use a 2-3/8 inch button, the Dortronics DRT5211-MP23 uses a 1-9/16 inch diameter button, and the SDC 430 Series uses a 1-1/2 inch round button. Head diameter drives the faceplate cutout, so swapping among these on an existing plate is not a like-for-like change. Where the 430 Series distinguishes itself is contact behavior rather than head size: heavy duty contacts built to withstand high impact and rated for heavy duty high frequency use, which is the specification that governs a point struck repeatedly.

15) For standardizing emergency release buttons across a facility, does the SDC 430 Series or a Camden or Dortronics mushroom cover more configurations from one series?

The SDC 430 Series carries the wider configuration range from a single series: seven models covering 431C and 431O alternate action on/off in SPST-NC and SPST-NO, 432C and 432O momentary in SPST-NC and SPST-NO, 432K momentary latching with key reset in DPST, 434 momentary DPST, and 435 alternate action DPST, in three finishes and two plate sizes. The comparable mushrooms are single configurations: the Camden CM-5000 is a mushroom pushbutton, the Camden CM-6000 a red locking mushroom, and the Dortronics DRT5211-MP23 a legended exit release on a single gang plate. Standardizing on the 430 Series means one series and one finish family across openings that need different contact arrangements.

16) Does the SDC 430 push button come pre-marked with Push to Exit or Emergency Release text?

The device options on the 430 Series are the blank plate (B), the LED indicators, and the red button (R), so signage is not how you specify it here. If you need the wording printed on the plate, the Dortronics 5210 exit release is supplied with Push to Exit / Emergency Release marking on a single gang plate. On the SDC, the usual approach is the red button on the 432K, which is what identifies an emergency station visually.

17) Is the SDC 430 mushroom switch heavy duty enough for a high traffic door or a shop floor?

That is what it is built for. The 430 Series is specified for heavy duty, high frequency use, with heavy duty contacts engineered to withstand high impact. It is a commercial-grade device, and it shows up on industrial equipment emergency stops as well as door release duty, so a busy loading dock or a hospital corridor release is within its intended service.
