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

Monitor protected steel doors with a compact 3/4 in. SPST door switch set intended for physical-security door-position circuits. The steel-door application and single-pole, single-throw contact arrangement make it suitable where an alarm panel, access-control controller, or other compatible security input needs a clear door-status change. Its white finish helps the installed contact blend with light-colored door and frame surfaces. Use the switch set at secured openings where door status is part of intrusion detection, access control, or facility monitoring. The 3/4 in. size provides a defined contact format for steel-door work, while the SPST configuration supports a single monitored circuit. Installers can apply the same switch type across multiple openings when a project requires matching door contacts rather than mixed contact styles. George Risk Industries 180-12-W 10 PACK groups ten steel-door switch sets in one package for multi-door work and stocked replacements. Select this configuration when the application calls for a 3/4 in. steel-door switch set with an SPST contact, rather than a different door material, contact arrangement, or switch size. The ten-set quantity is especially useful when several protected openings require the same door-status hardware.
