George Risk Industries 413PWG-B Contact Switch C-form

Product Description

The George Risk Industries 413PWG-B is a magnetic contact switch designed for door and window sensing applications in security and alarm systems. It features two C-form reed switch contacts, which provide both normally open and normally closed circuit configurations in a single unit, giving installers flexibility in how the switch is wired into a control panel or monitoring loop. The switch ships with 36-inch leads, allowing adequate wire length for most standard door and window frame installations without splicing. This type of component is typically installed by alarm system technicians, low-voltage electricians, and security integrators.

The 413PWG-B is suited for residential and light commercial security system installations where surface-mount or recessed magnetic contact sensing is required. Its dual C-form contact configuration makes it appropriate for applications that require both a normally open and normally closed output from a single sensing point, such as entry doors, windows, and access panels. The 36-inch lead length supports installations where the control wire must route through a door frame or wall channel before reaching the field wiring connection point.

Key Features

• Dual C-form reed contacts provide both normally open and normally closed circuit outputs
• 36-inch pre-attached leads reduce the need for field splicing at the sensor
• Magnetic actuation with no moving mechanical parts for long service life
• Compact form factor suited for door and window frame mounting
• Single-unit packaging allows per-opening inventory management

Compatibility

Designed as an OEM-style magnetic contact switch for use with standard low-voltage security and alarm control panels that accept C-form reed switch inputs.

Installation Notes

Installation is typically performed by licensed low-voltage technicians or alarm system integrators in accordance with applicable local codes and NFPA 731 guidelines for premises security systems. De-energize the control panel or zone circuit before connecting or disconnecting switch leads. Route leads through door frames or conduit as required to protect wire from mechanical damage. Verify switch gap tolerance against the actuating magnet specification before finalizing mount position.
