George Risk Industries 3030-TWG-W Spdt Window Contact White

Product Description

The George Risk Industries 3030-TWG-W is a single-pole double-throw (SPDT) window contact switch designed for residential security and alarm applications. This surface-mount magnetic contact fits windows and similar openings with a 3/8-inch gap tolerance. The wide-terminal design simplifies field wiring connections, reducing installation time and the chance of terminal errors. Finished in white, the unit blends with standard residential trim and frames. Licensed alarm installers and low-voltage technicians are the typical end users for this type of contact switch.

This contact is suited for residential intrusion detection systems, door and window monitoring circuits, and similar low-voltage alarm loops. The SPDT configuration provides both normally open and normally closed circuit options, giving installers flexibility to wire the contact for supervised or unsupervised loop configurations depending on panel requirements and job specifications.

Key Features

• SPDT switching configuration supports normally open and normally closed wiring options
• Wide terminal design for easier field termination and reduced wiring errors
• 3/8-inch mounting gap for standard residential window applications
• White finish for low-profile appearance on light-colored frames and trim
• Sold individually, one contact per unit

Compatibility

Designed as an OEM-style replacement or new-installation contact for residential window and door alarm circuits requiring an SPDT magnetic contact switch with wide terminals.

Installation Notes

Installation is typically performed by licensed low-voltage alarm technicians in accordance with local codes and NEC Article 725 for Class 2 and Class 3 circuits. De-energize the alarm panel or disconnect the loop before wiring the contact terminals. Verify the magnet-to-contact gap does not exceed the rated tolerance to ensure reliable actuation. Do not substitute the magnet component with an unmatched type, as gap tolerance and actuation reliability depend on the matched pair.
