Industrial 20 A Toggle Switch
The Bryant 4921GRY is a single-pole, double-throw toggle switch rated for 20 A at 120/277 V AC. It is built for industrial control panels and machinery where a momentary contact action is required.
Verify Wiring and Voltage Compatibility
Confirm your circuit operates within the 120/277 V AC rating and uses screw-terminal connections compatible with back or side wiring methods. The 1.7 in overall height must fit the enclosure depth, and the 2 hp motor rating should match the intended load.
Replaces Standard Maintained Toggle Switches
This momentary switch upgrades circuits needing automatic return to the centre-off position, such as jog controls or starter circuits. The jump is worth it when a maintained switch creates a safety risk by leaving motors energised unintentionally.

Questions about this item
Does the Bryant 4921GRY include mounting hardware or must I buy screws separately?
The switch body is supplied alone; mounting screws and a wall plate are not included and must be purchased separately.
How do I decide between the 120 V and 277 V ratings on the same 4921GRY?
The device is dual-rated; choose the voltage that matches your circuit — 120 V for standard lighting or 277 V for commercial fluorescent loads.
What does the 20 A rating mean when the switch controls a 2 hp motor?
At 20 A the switch can start and stop a 2 hp motor on either 120 V or 277 V AC circuits within its horsepower rating.
