Use this heavy-duty magnetic Garage Door Contact Switch on garage doors, roll-up doors and other doors or gates where it may be difficult to mount regular magnetic contacts. Smaller magnetic switches have a small operating gap where the contact and magnet must be within half an inch for reliable operation. While those switches are fine for most doors and windows in a home, they just won’t cut it for larger doors. These contacts can be as far as 2 3/4 inches apart and still operate.
- Use on large, loose-fitting doors and gates
- For Closed or Open Circuits
- Weatherproof die-cast aluminum
- UL listed for security systems
- Priced at $21.99
