George Risk Industries 180-36-W 10 PACK 3/4 Inch Steel Door Switch Set

Monitor steel-door openings with a compact 3/4 inch door switch set configured with an SPST normally open contact. This contact arrangement supports monitored door circuits that require an open electrical state when the switch is in its normal condition. The set is intended for steel-door security applications where a compatible door-position switch is required. George Risk Industries 180-36-W 10 PACK supplies 10 matching door switch sets for sites with multiple monitored openings. Using a common switch type across similar steel-door locations helps maintain consistent contact behavior at doors connected to security, intrusion, or access-control monitoring equipment. The 3/4 inch format is the defining size specification for this set. Within the George Risk Industries door-switch range, this version is distinguished by its steel-door application, SPST normally open circuit configuration, and ten-unit pack quantity. Specify the contact state carefully when replacing an existing door switch: normally open and normally closed circuits behave differently at the control panel. This pack is suited to projects requiring multiple identical normally open switch sets rather than a single replacement unit.
