The ECM INDUSTRIES LLC GSW-21 is a single pole single throw (SPST) push button switch rated for 10 amps at 125 volts and 1/3 HP. It operates on a push on/push off action, making it straightforward to integrate into control circuits without additional toggle hardware. The switch ships with 6-inch stripped wire leads for direct connection and is designed to mount in a 13/32-inch diameter hole. It is packaged on a card and sold in units of one each. Electricians and HVAC technicians install this switch in low-voltage and line-voltage control applications where a compact, reliable momentary or latching push button is required.
The GSW-21 is suited for residential and light commercial applications including HVAC equipment control panels, pump systems, small motor circuits, and general electrical enclosures. The 6-inch pre-stripped leads simplify field wiring and reduce installation time. The 13/32-inch mounting hole size fits standard knockouts and drilled panel openings commonly found in equipment cabinets and junction boxes. With a 1/3 HP motor rating, it handles small fractional horsepower loads in addition to standard switching duties.
Designed as an OEM-style replacement or new-installation push button switch for residential and light commercial electrical control panels, HVAC equipment, and small motor circuit applications requiring an SPST push on/push off switching function.
Installation should be performed by a licensed electrician or qualified HVAC technician in accordance with NEC requirements. Disconnect and lock out all power to the circuit before removing an existing switch or installing a new one. Ensure the mounting panel opening is 13/32 inches in diameter before securing the switch. Connect the pre-stripped leads to the appropriate circuit conductors using listed wire connectors suitable for the conductor gauge and ampacity of the circuit.
