Garage Door Contacts for Closed Circuits

Use this 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 apart and still operate. These Garage Door Contacts for Closed Circuits are used for systems that expect a closed circuit when the magnet and sensor are together. When the magnet and sensor separate, the circuit opens. This set is commonly used with security systems.Use on large, loose-fitting doors and gatesFor Closed CircuitsUL listed for security systemsManufacturer: Seco-Larm
