DynaLock 6335 Series - (1) Pushbutton, SPDT Maintained Contact

It latches. The 6335 is an alternate action, maintained contact SPDT pushbutton, so one press changes state and holds it until the next press. That makes it the right choice for turning a maglock circuit off and leaving it off (cleaning crews, deliveries, holding a door unlocked during business hours). If you want the door to release only while the button is held, you want a momentary device instead, such as the RCI 950 Series round push plate with handicap symbol or the Trine 342 narrow style electric door switch.

Yes. The 6335 comes in a compact surface mounted enclosure measuring 1 inch H x 2-1/4 inch W x 2 inch D, and it is built to be concealed under a desk or in a similar spot. No back box or wall cutout needed, just fasten the enclosure to the underside of the desk and run the wire.

Yes. DPDT contacts are an option on the 6335 in place of the standard SPDT. Take that if you need a second isolated set, typically to drop the lock on one pole and signal an alarm panel, access control input, or annunciator on the other. If you only need to break one circuit, the standard SPDT is enough.

They solve different problems. The Securitron EEB is an emergency exit push button with interchangeable LED lenses, and the ACSI 1320-1-MOM-ER is a pushbutton switch marked Emergency Release, both intended as identified emergency egress devices at the opening. The DynaLock 6335 is a plain unmarked station designed to be concealed under a desk or similar spot, so it is a staff release control rather than a marked emergency device. If your drawing calls for an emergency release at the door, specify the EEB or the ACSI 1320-1-MOM-ER instead.

The DynaLock 6335 is a surface-mounted station in a compact 1 inch H x 2-1/4 inch W x 2 inch D enclosure, intended to be concealed under a desk or similar location. If the button has to go into the wall face instead, the RCI 909 Series flush mount rocker switch is a flush-mounted device, and the RCI 908 Series electronic exit button carries red EXIT text for a marked egress location. Note that the RCI 909F-MO rocker is momentary operation, where the 6335 is alternate action maintained contact, so the 909F releases only while pressed.

The DynaLock 6335 uses an alternate action SPDT maintained contact, so one press latches the contact and the next press releases it. Among other release devices, the RCI 908 Series electronic exit button is also offered with maintained operation, and the RCI 919 Series rotary release button uses maintained operation as well. Momentary devices such as the RCI 950 Series round push plate and the RCI 909F-MO rocker switch will not hold the circuit after release.

The 6335 gives you a maintained on/off pushbutton only, with no key cylinder. It will hold a lock circuit open until someone presses it again, but anyone with access to the station can operate it, which is why it gets mounted concealed. If you need key control over the same function, the ACSI 1310-1 mortise keyswitch covers that duty.

The DynaLock 6335 is a pushbutton station, so anyone with access to it can operate it. Where the release has to be restricted to key holders, the ACSI 1310-1 is a mortise keyswitch from the 1300 Series. Where the actuator needs to carry the accessibility marking, the RCI 950 Series round push plate is furnished with a handicap symbol in satin stainless steel. Keep in mind the 950 plate is a momentary switch, while the 6335 is a maintained contact device.

The DynaLock 6335 is supplied with SPDT contacts as standard and can be upgraded to DPDT contacts, which gives you two independent transfer sets from a single button press for controlling a lock and an alarm shunt or monitoring point together. That contact upgrade is ordered on the 6335 itself, so you do not need to move to a different device such as the Securitron PB3 Series push button or the Trine 342 narrow style electric door switch.

The DynaLock 6335 enclosure measures 1 inch H x 2-1/4 inch W x 2 inch D and mounts to a surface, which suits a desk underside or a flat wall but not a narrow aluminum stile or mullion face. For that condition the Trine 342 is a narrow style electric door switch built for the tighter profile. It is worth confirming the switch action you need, since the 6335 provides alternate action maintained contact.

The 6335 is a commercial grade electronic access control device, a surface mounted station for switching door lock circuits. It is used in offices, schools, healthcare and multi-family common areas rather than as a residential doorbell type product.
