Bryant 4921 Industrial Toggle Switch
This brown toggle switch carries a 20 A rating at 120/277V AC and a 2 hp motor-load rating. The single-pole/double-throw momentary action suits industrial control panels and machinery circuits. NEMA WD-1 and UL20 compliance confirms it meets recognised safety standards. Screw terminals accept back and side wiring for secure installation.
Sustained Load Performance
The 20 A continuous current rating and 2 hp motor rating indicate reliable operation under prolonged industrial loads. Quiet-switch construction reduces mechanical noise during frequent actuation cycles. NEMA WD-1 listing verifies performance under repeated switching duty. The 1.7 in. overall height fits standard industrial enclosures without crowding adjacent components.
20 A Momentary Contact Rating
The defining specification is the 20 A, 120/277V AC momentary contact rating combined with a 2 hp motor-load capability. This determines suitability for industrial starter and contactor circuits requiring brief, high-current actuation. Buyers needing a maintained-contact switch or a different current rating should select an alternative model.

Questions about this item
Does the 20 A rating mean the 4921 toggle runs hot or draws extra power when left on all day?
The switch is a passive mechanical device; it draws no power itself and generates no measurable heat during continuous operation.
What wiring must already be in place for the 4921's screw terminals and back/side entry?
You need 120/277 V AC supply conductors sized for 20 A and a suitable junction box for the 1.7 in. tall switch body.
Will the 4921's single-pole/double-throw momentary action work with an older 120 V contactor coil?
Yes, the 120/277 V AC rating covers standard 120 V coils, and the momentary SPDT contacts can energise or de-energise them directly.
