Sdc 422PL1G Exit Device Push Button Spdt

Product Description

The SDC - SECURITY DOOR CONTROLS 422PL1G is a green illuminated momentary exit device push button featuring a single-pole double-throw (SPDT) switching configuration. Designed for access control and egress applications, this unit provides a reliable, low-voltage signal to control electric strikes, magnetic locks, or access control panels. The green illuminated actuator gives a clear visual cue for egress points, making it well-suited for commercial door hardware installations. Licensed electricians and access control technicians are the typical trade professionals who install this device.

The 422PL1G is used in commercial and institutional access control systems where a hardwired momentary exit request signal is required. It fits standard single-gang electrical box cutouts and is appropriate for interior egress doors in office buildings, schools, healthcare facilities, and similar occupancies. The SPDT output provides wiring flexibility to support both normally open and normally closed circuit configurations depending on the panel or controller requirements.
