About this item

Gardner Bender GSW‑21 Push On & Off SPST 10A 125VAC:

The Gardner Bender GSW‑21 is a rugged, motor‑rated maintained‑contact push‑button switch engineered for reliable performance in residential, commercial, industrial, automotive, and marine environments. Designed to deliver long‑lasting durability with smooth, consistent actuation, this switch uses a Push‑On / Push‑Off SPST mechanism, ideal for circuits requiring a stable ON or OFF state until manually changed.

Constructed with a robust housing and a clean black finish, the GSW‑21 is both functional and visually neutral, enabling it to blend into equipment panels, machinery housings, lighting systems, and control boxes. The switch comes equipped with 6-inch 18 AWG wire leads, simplifying installation and ensuring dependable electrical connectivity. Its motor-rated, high-current design makes it suitable for applications that demand more from a simple push-button switch.

Whether you're installing a new system or replacing a worn-out component, the GSW‑21 provides dependable performance backed by safety certifications and proven Gardner Bender quality.
