DynaLock 6337 Series - (2) Pushbuttons, Alternate Action SPDT

Yes. The 6337 station comes in a compact surface-mounted enclosure measuring 1 inch H x 2-1/4 inch W x 2 inch D, and DynaLock builds it to be concealed under a desk or in a similar spot. Surface mounting means no back box cut into the millwork, just fasten the enclosure where the operator can reach it.

Alternate action is a push-on, push-off latch: press once and the contacts stay transferred until someone presses again. That is what you want for holding a maglock or electric strike released for a delivery window, a shift, or a lobby door on free access. If you only want the door to release for the few seconds it takes someone to walk through, you want a momentary button instead, like the RCI 950 Series round push plate with the handicap symbol or the Trine 342 narrow style electric door switch. The 6337 carries two pushbuttons in the one enclosure, so you can run two separate alternate-action circuits from a single station.

The 6337 ships standard with SPDT contacts on each button, which gives you one common with a normally open and a normally closed leg per button. That covers most single-circuit jobs: break the maglock power, or signal a panel input. Order the DPDT upgrade when one press has to switch two isolated circuits at once, for example dropping lock power and simultaneously sending a dry contact to an alarm panel or shunt input without tying the two grounds together. DPDT is an option on the order, not a separate model.

The 6337 is an unmarked two-button station in a small surface enclosure, built to hide under a desk, so it is the wrong part when code or the AHJ wants a labeled release the public can find. For a marked device look at the ACSI 1320-1-MOM-ER pushbutton switch marked Emergency Release, the RCI 908 Series electronic exit button with red EXIT text and maintained operation, or the Securitron EEB emergency exit push button with interchangeable LED lenses. Those are wall-mounted, visible, and labeled. Keep the 6337 for the operator side of the opening.

The 6337 is a general purpose two-button control station with alternate action SPDT contacts in a plain surface enclosure, with no emergency marking or lens. When the application calls for a marked emergency release, the Securitron EEB emergency exit push button with interchangeable LED lenses and the ACSI 1320-1-MOM-ER pushbutton switch marked Emergency Release are the devices built for that purpose. The ACSI 1320-1-MOM-ER is momentary; the 6337 is alternate action, meaning the button latches its state rather than returning on release, which is a different behavior at an egress point.

Because a push-on, push-off button gives no other feedback. With a momentary button the door releases while your finger is down and the state is obvious. With the 6337's alternate action contacts the station can sit latched for hours, and without a lamp nobody at the desk can tell whether the door is currently held open or secure. The illuminated option is the cheap fix for that, and it is why it exists on this station.

The 6337 mounts on the surface, so it sits proud of whatever it is fastened to. If the design calls for a device set into the wall or a gang box, look at the Securitron PB4L Series illuminated halo with stainless push button or the Securitron PB5 Series medium round illuminated push button. Trade-off: those are single-button devices, while the 6337 gives you two independent buttons in one small enclosure.

No. The 6337 is an open pushbutton station with no key control, which is why DynaLock designs it to be tucked under a desk where only staff reach it. If the release itself has to be restricted, use a keyswitch such as the ACSI 1310-1 mortise keyswitch instead, or pair one with the pushbutton station so the key enables the circuit the buttons switch.

The enclosure is part of it. The 6337 station is furnished in its own compact surface-mounted housing at 1 inch H x 2-1/4 inch W x 2 inch D with both pushbuttons fitted, so all you supply is the fasteners into the mounting surface and the low-voltage wiring to the lock or panel.

A push button station lets anyone who can reach it operate the circuit. The ACSI 1310-1 mortise keyswitch from the 1300 Series requires a key to actuate and mortises into the wall or frame rather than surface mounting like the 6337, which is furnished in a surface-mounted enclosure. If the reason a desk-concealed station was specified was to keep unauthorized hands off the release, a mortise keyswitch solves the same problem at the opening itself.

They switch a door circuit but they are not interchangeable devices. The RCI 909F-MO is a flush mount momentary rocker switch rated 250VAC 10A with a beige finish, so it drops into a prepared opening in the wall or a device box and returns to rest when released. The DynaLock 6337 is surface mounted in its own compact enclosure and uses alternate action SPDT contacts, so its buttons hold state. Choose on two counts: whether the wall is prepped for a flush device, and whether the circuit expects a momentary pulse or a latched contact.

The 6337 can be ordered with the upgrade to DPDT contacts, so a second isolated set of contacts is available without leaving the series or changing the enclosure. Among peers, the RCI 909F-MO is a momentary rocker switch rated 250VAC 10A and the RCI 919 series rotary release button is a maintained device in satin aluminum, so if the requirement is two switched circuits from one operator, the DPDT option on the 6337 addresses it directly.

The 6337 uses alternate action contacts, so a press latches the state and a second press returns it. Two peers behave the same way at the opening: the RCI 919 series rotary release button has maintained operation in a satin aluminum finish and is turned rather than pressed, and the RCI 908-RE-MA electronic exit button has maintained operation with red EXIT text. All three keep the circuit in its commanded state without anyone holding the button, so the choice comes down to whether the operator is behind a desk or at the door and whether the device must be turned or pressed.

Commercial. The 6337 is a low-voltage electronic control station for access control work, sold into offices, institutional buildings, and multi-family entries rather than the home market. It switches a lock circuit, it does not lock anything itself, so the door still needs a maglock, electric strike, or panel input for the station to control.

The 6337 is a model within DynaLock's 6335 Series of pushbutton stations, all furnished in the same compact surface enclosures for concealed mounting. The 6337 specifically is the two-button alternate action SPDT configuration, so if the other openings in your building already run 6335 Series stations, this is the same family and the same mounting approach, ordered with the button count and contact action you need.
