George Risk PB-2020-W Recessed Plunger Contact 3/8 Inch White

Product Description

The George Risk Industries PB-2020-W is a pressure-fit recessed plunger contact switch designed for door, window, and access-point sensing applications. The plunger mechanism activates the internal contact when compressed by a door or frame surface, making it a reliable choice for alarm and security circuit integration. The white finish allows for low-profile installation in light-colored frames or trim. Sized at 3/8 inch in diameter, the PB-2020-W is designed to press-fit directly into a drilled hole, eliminating the need for additional hardware or threaded mounting during installation.

This recessed plunger contact is suited for residential and light commercial security installations, including door and window intrusion detection circuits. Electricians and alarm technicians install this type of switch in door frames, window sashes, and cabinet panels where a flush, concealed contact point is required. The press-fit design simplifies rough-in work and keeps the finished appearance clean and unobtrusive.

Key Features

Compatibility

Designed as an OEM-style replacement or new-installation recessed plunger contact for residential and light commercial door, window, and access-point security circuits requiring a 3/8 inch press-fit format.

Installation Notes

Installation is typically performed by licensed electricians or alarm system technicians. De-energize the circuit before wiring the contact leads to prevent shock hazard. Drill the mounting hole to the appropriate diameter to achieve a secure press fit. Follow applicable local electrical codes and manufacturer wiring guidelines when integrating into alarm or access control panels.
