Ecm Industries Llc GSW-SK Door Switch Single Pole

Product Description

The ECM INDUSTRIES LLC GSW-SK is a single-pole door switch designed for use in both AC and DC electrical systems. The switch is built with a brass mounting plate and a steel enclosure box, providing durable construction suited to trade applications. Its operating logic is straightforward: current turns on when the door opens and shuts off when the door closes. This makes it well-suited for indicator circuits, lighting control, and alarm trigger applications in HVAC equipment, electrical enclosures, and similar trade installations. Licensed electricians and HVAC technicians are the typical installers. The package quantity is 5 units per pack.

The GSW-SK is applicable to a wide range of residential and light commercial scenarios where a door-activated switching function is needed. Common install locations include electrical panels, HVAC unit access doors, utility enclosures, and equipment cabinets. Because the switch operates on both AC and DC systems, it fits into a broad range of control circuit configurations without requiring a dedicated power-type selection. The carded packaging makes it easy to stock and distribute for service truck inventory or parts-room use.

Installation Notes

Installation is typically performed by a licensed electrician or HVAC technician. De-energize the circuit and verify absence of voltage before beginning work, in accordance with NFPA 70 (NEC) lockout/tagout requirements. The brass mounting plate should be fastened securely to the door frame or panel surface before making wire terminations. Do not exceed the rated electrical load of the switch as specified by the manufacturer.
