Gri PB-100-W Push Button Plunger Switch 9/16 Inch

Product Description

The GEORGE RISK INDUSTRIES INC. PB-100-W is a reed-type push button plunger switch designed for use in low-voltage contact applications. The unit actuates via a spring-loaded plunger mechanism, triggering an internal reed contact element when compressed. At 9/16 inch, the plunger diameter is sized for standard panel cutouts and enclosure mounting scenarios. This switch is typically installed by alarm technicians, security integrators, electricians, and control panel builders working in access-control, door-monitoring, or industrial detection circuits.

The PB-100-W suits residential and light commercial applications where a normally open or normally closed reed contact output is needed at a recessed or surface-mounted point. Common install locations include door frames, equipment enclosures, control panels, and junction boxes where detecting physical displacement or plunger depression is part of the circuit logic. Its compact form factor supports tight-clearance installations common in control wiring work.

Key Features

• Reed contact element provides reliable, low-resistance switching in low-voltage circuits
• 9/16 inch plunger diameter suits standard panel and enclosure cutout dimensions
• Spring-loaded plunger returns to default position on release for consistent actuation cycling
• Compact single-unit package supports space-constrained panel and door-frame installs
• Sold individually, allowing single-point replacement or new-installation flexibility

Compatibility

Designed as an OEM-style replacement or new-installation reed plunger switch for low-voltage contact circuits in access control, security, and industrial control panel applications.

Installation Notes

Installation should be performed by a qualified electrician or licensed alarm and security technician in accordance with applicable NEC guidelines for low-voltage wiring. De-energize the circuit completely before removing an existing switch or making new wiring connections. Verify the plunger travel and alignment within the mounting cutout before securing the unit to ensure consistent actuation. Do not overtighten mounting hardware, as this can distort the switch body and affect reed contact operation.
