George Risk Industries 180-12WG-G 3/4 Inch Steel Door Switch Set

Monitor steel-door position at access-control and intrusion-detection points with a recessed contact switch and matching magnet set. The 3/4 in format fits door and frame preparations sized for cylindrical recessed contacts, helping maintain a less visible installation than surface-mounted hardware. A closed contact state indicates that the door is aligned with its magnet; separation changes the circuit state for the connected alarm panel, controller, or monitoring input. Steel doors require attention to contact placement because the ferrous door and frame can affect magnetic operation. This switch set is specified for steel-door use and is intended for installations where the contact and magnet are mounted across a moving door-to-frame gap. Installers should position the components so the door closes consistently and the magnet aligns with the switch body at the expected closed position. George Risk Industries 180-12WG-G 10 PACK supplies 10 switch sets for projects with multiple steel doors requiring the same 3/4 in contact format. The pack quantity supports uniform hardware selection across secured openings while retaining individual contact assemblies for each monitored door. Use it where the control system accepts a dry-contact door-status input and the physical opening is prepared for a recessed steel-door contact.
