Heavy-Duty SPST Toggle Switch

The Gardner Bender GSW-110 is a heavy-duty single-pole single-throw toggle switch designed for controlling electrical circuits. It features on/off faceplates and two screw-type terminals for secure wiring connections. The switch includes an O-ring seal that provides moisture and dust resistance for demanding environments. It is UL listed for safety compliance.

Ratings Define Practical Limits

The switch handles 10 amps at 277 volts AC and 20 amps at 12 volts AC for motor loads. It is also rated for 3/4 horsepower at 125 and 250 volts AC. These electrical ratings determine the maximum load the switch can safely control. Exceeding these values risks contact failure or overheating.

SPST Contact Form Decides Fit

The single-pole single-throw configuration means the switch opens or closes one circuit with a simple on/off action. It cannot alternate between two separate circuits or control a load from two locations. Buyers needing three-way or four-way switching must select a different contact form. The screw terminals accept standard wire connections for installation.

Questions about this item

Should I choose the 10A/277V AC rating or the 20A/12V AC rating for my circuit?

Select the rating that matches your supply voltage. Use 10A at 277V AC for mains circuits or 20A at 12V AC for low-voltage systems.

What does the 3/4 HP motor rating mean when the switch is installed?

It means the switch can directly control a motor up to 3/4 horsepower on 125V or 250V AC without a separate contactor.

How do the screw terminals and UL listing affect the installation?

The screw terminals accept solid or stranded wire for secure connections, and the UL listing confirms the switch meets US safety standards for the stated ratings.
