Camden CM-1290 Key Switch - Stainless Steel Key Switch DPDT Maintained

The Camden CM-1290 is a rugged, flush-mount, vandal-resistant key switch built to deliver flexible, reliable access control in commercial and industrial settings. As part of Camden’s CM series, it is configured with a DPDT maintained contact arrangement, making it ideal for applications where a stable “on/off” control with dual circuits is needed.
The CM-1290 supports both left and right operation, accepts standard 1″ to 1¼″ mortise cylinders, and is finished in durable stainless steel for indoor or outdoor use. 

Its design includes security features such as locators (to prevent cylinder spinning) and tamper-proof screws, making it suitable for public, semi-protected, or high-traffic installations.

Typical usage includes controlling electric strikes, overhead doors, bypass circuits, or dual relay control in access control systems.

Features

  • DPDT Maintained switch: provides dual circuits with a maintained action (i.e. pressing the key stays in position) 

  • Flush-mount stainless steel faceplate, durable and vandal resistant 

  • Left or right operation flexibility (i.e. can be configured based on user side) 

  • Accepts 1″ to 1¼″ mortise cylinders (cylinder sold separately) and works with standard cams 

  • Locators in the faceplate prevent cylinders from spinning or rotating unintendedly 

  • Tamper-proof screws included for secure mounting and anti-vandal protection 

  • Indoor / outdoor use capability (weather-resistant design) 

  • 3-year warranty typical for Camden key switches

  • LED options (in certain variants) — e.g. red 12 V LED in some models

Camden Door Controls CM-1290 – Frequently Asked Questions

1) What size opening do I need to mount the Camden CM-1290 key switch?
It is a flush mount switch that drops into a single gang opening. The faceplate and body measure 4-1/2 x 2-3/4 x 1-1/2 inches, so allow for that depth behind the plate in the wall or box. Tamper-proof screws are supplied for mounting.
2) What does DPDT maintained mean on a key switch, and when do I want it instead of momentary?
Maintained means the key turns the switch to a position and it stays there until someone turns it back, rather than pulsing once and releasing. Double pole double throw gives you two independent circuits switched at the same time, each with a normally open and a normally closed side. That is what you want for an on/off hold state, like putting an electric strike or overhead door into bypass, or driving two relays off one key turn. If you only need a single release pulse to let someone out, a momentary exit button is the right device instead.
3) Will the Camden CM-1290 switch handle 24VDC and the current my electric strike draws?
The switch is a dry contact device used at 12/24 V AC or DC with a 6 amp contact rating, which covers typical strike, maglock and relay coil loads in a low voltage access control system. It does not supply power itself, it only makes and breaks the circuit, so the strike still needs its own power supply.
4) I need an emergency release at this door, not a keyed switch. What should I use instead of the Camden CM-1290?
The CM-1290 is a stainless steel key switch that requires a mortise cylinder and key to operate, which is the opposite of what an emergency release needs. For a release anyone can hit fast, look at the Dortronics 5210 Series with a 1-9/16 inch diameter red mushroom push button marked Push to Exit / Emergency Release on a single gang plate, or the SDC 440 Series large mushroom button emergency exit switch with a 2-5/8 inch diameter heavy duty design. The Dortronics 5210 shares the CM-1290 single gang mounting, so the same box prep carries over.
5) For a code compliant exit device at an egress door, is the Camden CM-1290 the right switch?
The CM-1290 is a keyed DPDT maintained switch intended for controlling electric strikes, overhead doors, bypass circuits or dual relay control, and it needs a key in hand to operate. Where the requirement is a code compliant release at the egress side, the SDC 420 Series is an illuminated push button exit switch with 2 inch buttons and code compliance called out for that role. Keep the CM-1290 for the authorized override or bypass function rather than as the occupant's means of egress.
6) Can the CM-1290 key switch be installed outdoors on an exterior gate or overhead door?
Yes, it is rated for indoor or outdoor installation with a stainless steel faceplate and weather-resistant design. Operating temperature runs 32 F to 85 F. In climates that drop below freezing for long stretches, that lower limit is the number to check against your site.
7) Is the CM-1290 durable enough for a high traffic or public entrance?
Rated at 100,000 cycles, with a vandal-resistant stainless steel flush faceplate and tamper-proof mounting screws. Camden lists it as a commercial device, and the cylinder locators stop someone twisting the cylinder out of position. That combination is aimed at public and semi-protected locations rather than a back office.
8) Does the key switch need to be ordered for left or right hand operation?
No handing decision at the order stage. The CM-1290 supports both left and right operation, so it can be set up for the side the user turns toward during install.
9) Should I use a key switch or a push button for releasing a door?
They do different jobs. A key switch like the Camden CM-1290 restricts operation to whoever holds the key and holds its state, which suits bypass, overhead doors and anything you want locked out from the general public. A push button is unrestricted and momentary, for free egress or a request to exit anyone can press. For that side of the job ZenSupply carries the SDC 410 Series narrow frame mount illuminated exit switch, the SDC 420 Series with 2 inch buttons, and mushroom style emergency releases such as the SDC 430 Series 1-1/2 inch button, the SDC 440 Series 2-5/8 inch button, and the Dortronics 5210 Series 1-9/16 inch red mushroom on a single gang plate.
10) For an industrial overhead door, how does the Camden CM-1290 compare with the SDC 430?
Both suit rough service. The Camden CM-1290 has a vandal resistant stainless steel flush faceplate with tamper proof screws and cylinder locators, DPDT maintained contacts rated 6 A typical at 12/24 V AC/DC, and a 100,000 cycle switch life, and it is listed for indoor or outdoor installation. The SDC 430 Series is a heavy duty industrial mushroom button switch with a 1-1/2 inch round button, operated by hand rather than by key. Choose the CM-1290 when the overhead door control has to be restricted to a keyholder and latch on; choose the 430 when operators need a large button they can hit with a gloved hand.
11) I need a lighted switch so staff can find it in a dark corridor. Does the Camden CM-1290 do that, or should I pick something else?
The Camden CM-1290 is a stainless steel key switch; LED options appear on certain CM series models rather than as a standard feature of the DPDT maintained key switch. If an illuminated face is the deciding factor, the SDC 410 Series is an illuminated push button exit switch with a narrow frame mount and the SDC 420 Series is an illuminated push button exit switch with 2 inch buttons. Both are hand operated, so you give up the key restriction and the maintained latching action that the CM-1290 provides.
12) What finish is the Camden CM-1290 faceplate, and will it match other stainless trim in the building?
The faceplate is stainless steel in the US32D / C32D satin stainless finish, which is the standard commercial finish most switch plates, strikes and lever trim are specified in. It will sit consistently alongside existing 630/32D hardware on the same run of openings.
13) Is the Camden CM-1290 a wireless or networked device?
No. It is a hard-wired mechanical key switch with no wireless communication and no onboard electronics to program. You run low voltage wire from its contacts to the strike, relay or access control input you are switching.
