A magnetic switch detects the relative position of a magnet and contact, making it useful for monitoring doors and shutters through a connected alarm circuit. Garrison offers compact door contacts and shutter contacts so installers can select a mounting arrangement suited to the opening.
The LK-153 is a small magnetic switch with an ABS resin housing and brown or ivory color options. Its listed operating distance is 15 mm, with a 0.1 A, 100 VDC contact rating and 5 W contact capacity. These figures apply to LK-153 rather than the whole category.
Door material, frame geometry and installation clearance affect contact selection. Confirm the required contact state, electrical load and mounting position before ordering. For larger shutters, compare bracket arrangement and mechanical protection instead of choosing solely by appearance.
Provide the door or shutter type, available mounting space, required operating gap and alarm-panel input details. Include the model reference and quantity when requesting Garrison pricing.
