Bryant 4921W 20A 3-Pole Momentary Contact Switch

Bryant 4921W 20A 3-Pole Momentary Contact Switch

The Bryant 4921W is a 20A momentary contact switch engineered for control circuit applications that call for precise, temporary circuit actuation rather than continuous on/off switching. Configured as a 3-pole, 2-circuit device, it allows a single switch body to manage multiple control functions from one compact footprint, which helps reduce panel space and simplify wiring in control cabinets and equipment enclosures. Momentary contact switches like the 4921W are commonly specified wherever an operator needs to trigger a control action, such as a jog, pulse, or interlock function, without holding the circuit closed for an extended period. This makes the switch a practical fit for industrial and commercial control panels, machine control stations, and other applications where a brief, spring-actuated switching event is required to initiate or interrupt a control function. As part of Bryant's line of control and switching devices, the 4921W is built to support dependable, repeatable performance in demanding electrical control environments where switch quality directly affects equipment uptime.

Key Features

• Amperage Rating: Rated 20A, giving the switch the electrical capacity needed for control and switching circuits in industrial and commercial systems.
• 3-Pole Configuration: A three-pole design allows a single switch body to control multiple circuit paths at once, simplifying control panel layouts that would otherwise require several separate switches.
• 2-Circuit Configuration: The 2-circuit configuration supports control schemes that require switching two separate circuits from a single device, useful for sequencing or dual-function control tasks.
• Momentary Contact Action: Momentary switching action is suited to jog, pulse, interlock, and similar control functions where continuous contact closure is not required or desired.
• Control-Grade Design: Constructed for use in control panels and industrial switching applications where reliable, repeatable actuation is essential to equipment operation.
• Compact Multi-Function Footprint: Combining 3-pole, 2-circuit switching in one momentary contact device helps consolidate control functions and reduce the number of components needed in a panel build.
