George Risk Industries 4532D-36 Mini Overhead Door Switch

Product Description

The George Risk Industries 4532D-36 is a miniature overhead door switch with a double-pole double-throw (DPDT) configuration. It is designed to monitor the open and closed position of overhead doors, providing a reliable electrical signal to alarm panels, access control systems, or automation controllers. The DPDT contact arrangement gives installers flexibility to wire both normally open and normally closed circuits simultaneously from a single device. Security and low-voltage systems technicians typically install this switch as part of a door monitoring or intrusion detection circuit.

This switch is suited for commercial and industrial overhead door applications where a compact, discreet form factor is required. It mounts directly to the door frame or header and actuates as the door travels. Common installation scenarios include loading dock doors, warehouse roll-up doors, and commercial garage doors where position feedback is needed for security or automation systems. The DPDT output makes it adaptable to a wide range of control panel input requirements.

Key Features

• Double-pole double-throw (DPDT) contact configuration for simultaneous NO and NC circuit wiring
• Miniature form factor suited for low-profile overhead door frame mounting
• Designed for overhead door position monitoring in security and access control applications
• Single-unit packaging for straightforward one-for-one replacement or new installation

Compatibility

Designed as an OEM-style replacement or new-installation switch for overhead door monitoring circuits used in commercial and industrial security and access control systems.

Installation Notes

Installation is typically performed by a licensed low-voltage or security systems technician. Disconnect and de-energize the alarm panel or control circuit before wiring the switch. Mount the switch to a fixed surface on the door frame and position the actuating magnet or trigger on the door leaf so contact changes state fully at both the open and closed positions. Follow all applicable local electrical codes and manufacturer wiring diagrams when terminating DPDT contacts to the control panel.
