Gri GI-PBF100TWW1K Push Button Plunger Switch 1K Resistor

Product Description

The GEORGE RISK INDUSTRIES INC. GI-PBF100TWW1K is a 3/4 inch push button plunger switch with an integrated 1,000 ohm (1K) resistor, designed for special application contact circuits. The built-in resistor allows this switch to function in end-of-line resistor (EOLR) supervised circuit configurations commonly required in security and alarm system wiring. This type of switch is typically installed by alarm technicians, electricians, and low-voltage security system integrators where supervised loop integrity is required. The plunger-style actuator provides a reliable, positive make-or-break contact action suited to panel, enclosure, or door-frame mounting.

This switch is suited for special application contact scenarios including security alarm loops, access control panels, and supervised detection circuits in both residential and light commercial installations. The 3/4 inch form factor fits standard knockout or drilled mounting holes common in metal and plastic enclosures. Installers working on supervised alarm circuits benefit from the integrated 1K ohm resistor, which eliminates the need to add a discrete resistor in series at the end of the loop.

Key Features

• Integrated 1,000 ohm resistor supports end-of-line supervised circuit configurations
• 3/4 inch plunger-style push button actuator for positive contact actuation
• Designed for special application contact use in alarm and security systems
• Sold individually (each) for single-point replacement or new installation
• Compact form factor fits standard enclosure knockouts and panel cutouts

Compatibility

Designed as an OEM-style special application contact switch for supervised alarm loop and security panel circuits requiring an integrated end-of-line resistor configuration.

Installation Notes

Installation should be performed by a licensed low-voltage technician or qualified electrician in accordance with applicable local codes and NEC Article 760 for fire alarm or signaling circuits. De-energize the circuit and discharge any capacitive voltage before handling or wiring the switch. Verify that the 1K ohm resistor value matches the supervision requirements of the control panel before installation. Do not exceed the rated electrical limits of the switch as specified in the manufacturer datasheet.
