George Risk PBF-100-W Recessed Plunger Flange Switch White

Product Description

The George Risk Industries PBF-100-W is a recessed plunger-style flange switch designed for use in door and window contact applications. The unit features a 3/4-inch diameter plunger body with a flange mount configuration and ships in white to blend with light-colored door frames and casings. This type of recessed contact is a core component in security alarm and access control wiring, providing a normally open or normally closed circuit signal when a door or window is opened or closed. Installation is typically performed by low-voltage alarm technicians or electricians working on security system rough-in.

The PBF-100-W is suited for residential and light commercial security installations where a concealed, flush-mounted contact point is required. The flange design allows the switch body to seat flush against the door frame or surface, keeping the contact hidden from view when the door is closed. It is commonly installed in wood or hollow-core door frames as part of a hardwired intrusion detection circuit.

Key Features

• Recessed plunger design keeps contact concealed within the door frame
• Flange mount configuration provides a secure, flush seating surface
• 3/4-inch diameter plunger body fits standard recessed contact bores
• White finish for compatibility with light-colored frames and trim
• Sold individually as a single unit

Compatibility

Designed as an OEM-style recessed plunger flange contact for residential and light commercial door and window alarm circuits requiring a 3/4-inch diameter recessed switch.

Installation Notes

Installation is typically performed by a licensed low-voltage technician or alarm systems installer. Before servicing or replacing any contact in an active security circuit, disable the zone at the control panel to prevent false alarms. A standard hole saw or spade bit sized to 3/4 inch is used to bore the recess in the door frame. Follow all local electrical codes and the system manufacturer wiring guidelines when terminating leads.
