Heavy-duty single-pole ON-OFF toggle switch with screw terminals, rated 20 A at 125 V AC and 10 A at 277 V AC. Maintained action — it stays where you set it.

Use it for: manually switching lights, pumps, fans, motors and equipment on control panels, machinery, workbenches and shop equipment. Screw terminals take a ring or spade terminal, or bare wire, for a secure, serviceable connection. Mounts in a standard 1/2" hole.

Before using it on a 12 V DC vehicle or boat circuit: the published ratings are for AC. DC is harder on switch contacts, so confirm the DC rating for your load or choose a DC-rated switch from our toggle switches or rocker switches.

Priced per piece — order any quantity. Need a metal body? See the die-cast chrome version.
