George Risk Industries 120T-12-B Molded SPST-NO Switch Set

Add a normally open switching point to a physical security circuit with a molded 80-case switch set. The single-pole, single-throw contact arrangement provides one circuit path and operates in its normal open state. This configuration is used where the connected security panel, relay, annunciator, or monitoring device is intended to supervise an open-contact input. The molded case format provides a defined housing style for installations where the enclosure and switch arrangement must match an existing security-system requirement. Select the contact state carefully: SPST-NO identifies a single circuit with a normally open condition, rather than a multi-pole or normally closed arrangement. That distinction affects how the connected circuit interprets the switch condition. George Risk Industries 120T-12-B is supplied as a switch set in the molded 80 case configuration. It is appropriate for security technicians replacing a like-for-like molded switch set or building a circuit that specifically calls for normally open SPST operation. Confirm the required contact logic, mounting location, wiring method, and connected control equipment before installation so the switch behavior matches the circuit design.
