DynaLock 6220 Series Palm Switch Buttons, Alternate-Action DPDT

Alternate-action means the 6220 latches: press once and the contacts change state and stay there, press again and they return. DPDT gives you two independent sets of changeover contacts, so you can unlock a mag lock on one set and signal the panel or an alarm shunt on the other. Use it where the door needs to stay unlocked until somebody presses again, like a shipping door or a reception release held open during business hours. If you want the door to release only while the button is pressed, you want a momentary switch instead, such as the RCI 950 Series round push plate.

Three plate choices. The standard plate is supplied unless you pick an option; for a narrow frame or mullion there is a narrow plate at 1-3/4 inches wide, and for larger boxes there is a two gang faceplate at 4-9/16 inches wide. Pick the narrow plate when you are mounting on a hollow metal frame face or a storefront stile that will not take a single gang plate.

Several, depending on what you want the button to do. For a round push plate with the handicap symbol, the RCI 950 Series is a momentary switch in satin stainless. For a narrow frame or mullion in another brand, the Trine 342 is a narrow style electric door switch. For a labeled emergency release, the Securitron EEB with interchangeable LED lenses or the ACSI 1320-1-MOM-ER marked Emergency Release. For a maintained-operation button in the RCI line, the 908 Series with red EXIT text. Only the 6220 gives you alternate-action DPDT switching in a palm switch plate.

The DynaLock 6220 is an alternate-action DPDT palm switch, meaning each press toggles and holds the contact state until the next press. If the opening needs the contact to make only while the button is held, use a momentary device instead: the RCI 950 Series round push plate with handicap symbol is a momentary switch in satin stainless, the ACSI 1320-1-MOM-ER pushbutton is a momentary switch marked Emergency Release, and the RCI 909 Series flush mount rocker is a momentary switch rated 250VAC 10A. Choose based on whether you want a large push plate, a labeled emergency release, or a flush rocker.

For a latching, maintained-contact release the closest peers are the RCI 908 Series electronic exit button with red EXIT text in maintained operation, and the RCI 919 Series rotary release button with maintained operation in a satin aluminum finish. Both hold their state after actuation like the alternate-action 6220 does. The difference is the operator: the 6220 is a palm button on a stainless faceplate in brushed stainless steel US32D, the 908 is a labeled EXIT button, and the 919 is turned rather than pressed.

The DynaLock 6220 is offered with a narrow plate 1-3/4 inches wide as well as a two-gang faceplate 4-9/16 inches wide. If you need a purpose-built narrow-style device instead, the Trine 342 is a narrow style electric door switch. For a narrow application choose between the 6220 on its 1-3/4 inch plate and the Trine 342.

The 6220 is a general request-to-exit palm switch and is not labeled for emergency use. For a station that has to read as an emergency release, the ACSI 1320-1-MOM-ER is a pushbutton switch marked Emergency Release, and the Securitron EEB is an emergency exit push button with interchangeable LED lenses. Use one of those where the code official or spec calls for a marked emergency egress device, and keep the 6220 for standard REX locations.

Yes. The 6000 Series controls it belongs to are request-to-exit (REX) controls, offered in several switching configurations. The 6220 is the alternate-action DPDT version, so one pole can drop the lock and the other can shunt the door contact at the access control panel while it is latched.

Yes, an anti-tamper switch is an available option on the 6220. It is the one to specify on exterior-facing or public-side installations where you want the panel to know if the plate is removed. It can be combined with the LED, the green button, the narrow plate or the two gang plate.

The DynaLock 6220 can be ordered with a bi-color red/green LED at 12/24 VDC as an option on the faceplate. If you would rather have illumination built into the button itself, the Securitron PB4L is an illuminated halo with a stainless push button and the Securitron PB5 is a medium round illuminated push button. The 6220 route gives you a separate LED indicator alongside a red or green palm button; the PB4L and PB5 light the button or its surround.

They serve the same purpose - a wall or frame mounted push button release for an electrified opening - but they are not identical devices. The DynaLock 6220 is an alternate-action DPDT palm switch in brushed stainless steel US32D with optional anti-tamper switch, bi-color LED, green button, narrow plate and two-gang faceplate. The Securitron PB3 is a push button from the PB3 Series. Confirm the switching action and contact configuration your control circuit needs before treating one as a drop-in for the other.

A push button like the 6220 can be operated by anyone who reaches it; the 6220 adds an anti-tamper switch option but the button itself stays accessible. Where only authorized staff should release the door, use a keyswitch instead: the ACSI 1310-1 is a mortise keyswitch from the 1300 Series. That restricts actuation to a keyholder rather than relying on button placement.

The 6220 is a palm switch with a red or green button on a stainless faceplate, sized for a hand press at a REX location. Where the actuator has to be identified as an accessible control, the RCI 950 Series round push plate carries a handicap symbol and is a momentary switch in satin stainless. That symbol and plate format is what accessible entrance specs normally call for, so the 950 is the better match for that duty.

Red is the standard button color. Green is available as an option and is worth using where the button is a normal-use exit or unlock control rather than an emergency release, so staff do not confuse it with an emergency exit push button.

Brushed stainless steel, US32D, is the standard finish. That is the common commercial satin stainless finish, so it lines up with US32D levers, push plates and exit device trim already on most commercial openings.

It is a commercial access control device, not a residential one. The 6220 is a stainless-plate REX palm switch built for access-controlled openings in commercial and institutional buildings, wired to a panel or mag lock power supply rather than to a doorbell transformer.
