Sdc 424UL1R Momentary Dpdt Push Button Switch Red

Product Description

The SDC - SECURITY DOOR CONTROLS 424UL1R is a momentary double-pole double-throw (DPDT) push button switch finished in satin chrome (630) with a red illuminated actuator. It is designed for access control and door release applications where a momentary contact signal is required to trigger an electric strike, magnetic lock, or access control panel. The DPDT configuration provides two independent switching circuits in a single actuator, giving installers flexibility in wiring normally open and normally closed outputs simultaneously. Security integrators and licensed electricians install this device in commercial and institutional entry systems.

The 424UL1R is suited for commercial door control installations where a wall-mounted momentary switch is needed to initiate door release or request-to-exit functions. The red illuminated button provides a clear visual indicator for occupants, making it appropriate for use at egress points, reception desks, secured lobbies, and controlled corridor entries. Its satin chrome finish integrates with standard commercial hardware finishes in office, healthcare, and government facility environments.

Installation Notes

Installation should be performed by a licensed electrician or credentialed security systems integrator in accordance with applicable NEC requirements. Disconnect and de-energize all connected access control equipment and door hardware power supplies before wiring or replacing the switch. Verify that the DPDT contact ratings are compatible with the load requirements of the connected electric strike or magnetic lock controller before energizing. Do not exceed the rated electrical load on either pole of the switch.
