Unique-Bargains 5 Pcs Recessed Door Window Magnetic Reed Switch Alarm Normally Open Control Sensor

Recessed Magnetic Reed Switches

This pack contains five normally open reed switches designed for recessed installation in doors or windows. When a magnet approaches within the actuation distance the circuit closes, sending a signal to the connected alarm system. The sensors suit home automation projects and light commercial security setups where discreet mounting is required. Each unit ships new in a brown ABS housing.

100 V 10 W Switching With Short Cable

The contacts are rated for 100 volts and 10 watts, suitable for low voltage alarm circuits rather than mains switching. A 33 cm lead provides enough length for typical frame routing without excess slack. Actuation occurs between 0 and 15 mm, so the magnet must sit close to the switch body for reliable operation. Power draw is negligible when the circuit is open.

Five Piece Pack With Compact ABS Bodies

Each sensor measures approximately 2.5 by 2.3 cm and weighs 80 g for the complete set of five. The brown ABS housing blends with wooden frames and resists everyday knocks. Recessed mounting means drilling a hole in the frame, which suits permanent installations but not temporary or rental scenarios. The short cable limits placement to positions near the control panel or junction box.
