Nascom N1178CTB/SWFB Recessed Contact Terminal

Product Description

The NASCOM N1178CTB/SWFB is a recessed contact with a 3/4 inch stub plunger configuration and terminal-style wiring connections. Recessed contacts are magnetic security sensor components installed into door and window frames to detect open or closed states. The plunger-style body sits flush within a drilled cavity in the frame, keeping the contact concealed and protected from physical interference. Electricians and low-voltage security technicians install these as part of wired intrusion detection and access control systems. The terminal connection type simplifies field wiring during rough-in and finish work.

This recessed contact is suited for residential and light commercial security installations where a clean, concealed appearance is required. The 3/4 inch stub plunger format fits standard drilled frame openings common in door and window framing applications. It is sold as a single unit, making it practical for individual replacement or new-point installations on existing alarm system loops.

Installation Notes

Installation is typically performed by a licensed low-voltage or alarm systems technician. Power down or disarm the alarm system panel before connecting or disconnecting wiring at any zone terminal. Drill the frame cavity to the correct diameter and depth to ensure flush seating of the plunger body. Follow local low-voltage wiring codes and the panel manufacturer guidelines for zone loop wiring practices.
