Wired magnetic contact switch for doors, windows and roller shutters. Strong magnets and a sensitive reed contact are designed for reliable detection and long durability.
Keep Children and Pets Safe – With Wired Magnetic Contact Detection
A magnetic reed contact closes when the magnet aligns with the sensor, creating a clear open/closed signal on the wired line. The wired part mounts on the fixed frame while the mating magnet sits on the moving door or shutter.
Immediate registration of opening events helps carers notice exits quickly, reducing the chance of children or pets leaving the property unnoticed.
Reliable Intruder Alerts – Thanks to Strong Magnetic, Sensitive Reed Switch
A robust magnet creates a distinct magnetic field that actuates the reed switch reliably, while sensitive switching detects small movements that indicate openings. The construction emphasises long-term contact performance under repeated cycles.
Faster, more consistent signalling to an alarm panel supports prompt response to unauthorised entry attempts.
Quick Replacement for Existing Systems – With Simple Wired Mounting
Wired contacts are designed for installation on a fixed frame with the magnet on the corresponding door or shutter, matching conventional alarm wiring layouts. The compact form reduces alignment fuss during fitting.
Swapping older contacts is straightforward, cutting installation time and allowing continued use of legacy wired alarm panels.
