George Risk Industries 4532-120 Overhead Door Switch

Product Description

The George Risk Industries 4532-120 is a mini overhead door switch with a 10 inch arm lead, designed for use in door contact and position-sensing applications. This compact switch mounts to overhead door assemblies and signals open or closed status to security, alarm, or access control systems. The arm lead actuates the switch mechanism as the door travels, providing a reliable electrical signal for monitoring or control circuits. Licensed security and electrical technicians are the typical installers for this type of device in commercial and residential overhead door systems.

The 4532-120 is suited for overhead door installations where a compact, arm-actuated contact switch is required. Common applications include commercial roll-up doors, sectional garage doors, and similar overhead door assemblies where position monitoring is needed for alarm panels, building automation systems, or access control integration. The unit is sold individually and is appropriate for both new installation and replacement service work.

Key Features

• Mini form factor suits space-constrained overhead door installations
• 10 inch arm lead provides mechanical actuation travel for door position sensing
• Designed for overhead door contact and position monitoring applications
• Sold as a single unit for straightforward replacement or new install

Compatibility

Designed as an OEM-style replacement or new-installation overhead door contact switch for residential and commercial overhead door systems requiring arm-actuated position sensing.

Installation Notes

Installation is typically performed by a licensed electrician or security systems technician. Disconnect and lock out all power to the door operator and associated control circuits before beginning work. Mount the switch body to a fixed surface and align the arm lead so it actuates cleanly through the full travel range of the door. Wiring should comply with applicable NEC requirements for low-voltage signal wiring.
