George Risk Industries 180-12-G 10 PACK 3/4-Inch Steel Door SPST Switch Set

Provide door-position switching for steel-door security applications with a 3/4 in SPST switch set. A single-pole, single-throw contact provides one switched circuit for connection to compatible door-monitoring, alarm, or access-control wiring. The compact 3/4 in size identifies the contact format required at the opening, helping installers match the switch set to the prepared door location. Steel doors present a specific installation environment for door-position hardware. This switch set is specified for steel-door use rather than as a general-purpose hardware item, making that application detail central when selecting it for protected openings. The SPST configuration is appropriate where the connected system needs a single contact state from the door. Each package contains ten switch sets, supporting multiple doors that require the same contact style and circuit arrangement. George Risk Industries 180-12-G 10 PACK groups ten matching 3/4 in steel door switch sets in one package. Select it when the installation calls for SPST door contacts for steel openings and a quantity of ten sets. Its distinguishing details are the steel-door application, 3/4 in switch size, SPST contact arrangement, and ten-set package quantity.
