Nascom N1178WSHK/STDD Recessed Contact Dpdt

Product Description

The NASCOM N1178WSHK/STDD is a recessed door and window contact designed for use in security and access control systems. This unit features a double-pole double-throw (DPDT) reed switch configuration, a 1-inch stub body for flush mounting, and 12-inch shark-style lead connections for quick, secure termination. Recessed contacts of this type are typically installed by alarm technicians, security integrators, and electricians working on low-voltage detection circuits. The DPDT output provides both normally open and normally closed signal paths simultaneously, giving the installer flexibility in circuit configuration.

This recessed contact is suited for residential and light commercial door or window applications where a concealed, tamper-resistant sensor is required. The 1-inch stub form factor fits standard bored holes in wood or metal door frames and matching door or window sash. The 12-inch shark leads simplify wire connection to control panels without the need for additional terminal blocks at the sensor. It is sold as an individual unit.

Key Features

• DPDT reed switch provides both normally open and normally closed circuit paths in a single device
• 1-inch stub body designed for flush recessed mounting in door frames or window sashes
• 12-inch shark-style leads allow direct, tool-free wire termination
• Recessed form factor keeps the sensor concealed and reduces tamper exposure
• Single-unit packaging for straightforward inventory and job-site management

Compatibility

Designed as an OEM-style recessed contact for standard low-voltage security and access control detection circuits requiring a DPDT reed switch in a 1-inch stub configuration.

Installation Notes

Installation is typically performed by licensed low-voltage security technicians or electricians in accordance with local codes and NEC Article 725 for Class 2 and Class 3 remote-control and signaling circuits. Power down the control panel or disable the zone before connecting or disconnecting leads. Ensure the stub body and magnet are aligned within the manufacturer-recommended gap tolerance for reliable actuation. Do not overtighten or force the stub into undersized bores, as this may damage the reed switch inside the housing.
