Nascom N400G/ST018 Recessed Contact Bar Switch

Product Description

The NASCOM N400G/ST018 is a recessed contact switch designed for industrial bar closed loop applications. This type of switch is used to monitor the open or closed status of a door, hatch, or panel in a secured or monitored loop circuit. When the actuating bar is engaged, the contact closes the loop; when the bar is removed or displaced, the circuit opens and triggers the connected monitoring system. Security integrators, industrial electricians, and access-control technicians are the primary trades that specify and install this device.

This recessed contact switch is suited for industrial environments where surface-mount switches are not practical or where a flush-mount profile is required. Typical installations include industrial enclosures, equipment access panels, and facility perimeter doors where loop-style alarm or monitoring circuits are used. The unit is sold individually and is intended for professional installation in commercial and industrial settings.

Key Features

• Recessed mounting design keeps the switch protected and low-profile
• Bar-style actuator operates a closed loop circuit configuration
• Sold as an individual unit for single-point installation
• Industrial-grade construction suited for demanding environments

Compatibility

Designed as an OEM-style replacement or new-installation recessed contact switch for industrial bar closed loop monitoring circuits.

Installation Notes

Installation is typically performed by a licensed electrician or qualified security systems technician. De-energize the loop circuit and verify the line is not live before wiring the switch. Follow applicable NEC guidelines for low-voltage control wiring. Confirm proper alignment of the bar actuator with the recessed body to ensure reliable contact operation after installation.
