1KX Exterior Open / Close Key Switch – Tamper-Proof NEMA 4 Surface Mount

The 1KX is a heavy-duty exterior key switch designed for controlled operation of compatible commercial garage doors, rolling grilles, shutters, gate operators, and other access-control equipment.

The spring-return key switch provides dedicated OPEN and CLOSE commands while requiring an authorized key for operation. After the key is turned in either direction, it automatically returns to the center position.

A rugged die-cast aluminum enclosure and tamper-resistant design make the 1KX well suited for commercial and industrial locations where door operation needs to be restricted to authorized personnel.

Open / Close Key Operation

The 1KX uses a center-return key switch.

Turn the key in one direction to activate the OPEN circuit and in the opposite direction to activate the CLOSE circuit.

When released, the key automatically returns to the neutral center position.

This provides simple authorized control without leaving an OPEN or CLOSE command continuously activated.

Controlled Access

Because operation requires a key, the 1KX is ideal for locations where standard push-button controls could allow unauthorized door or gate operation.

Common applications include:

• Warehouses

• Commercial garages

• Industrial buildings

• Rolling steel doors

• Storefront grilles

• Security shutters

• Parking structures

• Automatic gates

• Restricted-access areas

• Service entrances

Exterior NEMA-Rated Enclosure

The metal enclosure carries NEMA 3R, 4, and 12 ratings, providing protection suitable for many installations exposed to:

• Rain

• Moisture

• Dust

• Dirt

• Windblown debris

• Commercial and industrial environments

Proper conduit, fittings, and installation methods should be used to maintain the required environmental rating.

Compatibility

The 1KX is designed for compatible operators and control systems that accept separate momentary OPEN and CLOSE control inputs.

Before ordering, verify:

• Operator control voltage

• Open / Close input requirements

• Wiring configuration

• Required switch contact arrangement

• Installation environment

• Required enclosure rating

Do not assume compatibility based only on the operator brand.

Package Contents

Control wiring, conduit, fittings, operator, and other installation accessories are sold separately unless specifically supplied with the unit.

Important Installation Note

Disconnect operator power before installation or servicing.

Wire the key switch according to the operator manufacturer's wiring diagram and test both OPEN and CLOSE functions after installation.

This key switch is an activation device and does not replace required monitored photo eyes, sensing edges, light curtains, or other entrapment-protection equipment.
