George Risk Industries 4400A Industrial SPST Armored Switch Set

Monitor a protected opening in a wired security circuit with an industrial single-pole, single-throw contact set. George Risk Industries 4400A-48 combines the contact assembly with a 4 ft armored cable, placing a protected cable lead at the device location. Its SPST switching arrangement provides one discrete circuit state for an alarm panel, input module, or similar security interface. The 4 ft armored-cable configuration is the defining characteristic of this switch set. Use it where the contact lead may be exposed to movement, abrasion, or accessible cable routing near a door, gate, cabinet, or other monitored opening. Four feet of cable gives the installer a defined reach from the contact location to the first field connection while retaining an armored outer construction along that run. Select this configuration when the security design calls for a hardwired industrial contact with a single switching circuit and an attached armored lead. It fits intrusion detection, access-controlled openings, equipment enclosures, and other applications that report open or closed status to a connected control system. Installation planning should account for cable routing, connection method, mounting geometry, and the electrical requirements of the receiving circuit.
