Magnetic Contact

Plastic door/window magnetic contact (reed switch + magnet) for security and access-control systems — used to detect whether a door or window is open or closed. The reed switch mounts on the frame and the magnet on the moving door or window. When the door is closed the magnet holds the reed contacts in their normal state; opening the door breaks the magnetic field and changes the contact state, signalling the alarm or control panel over low-voltage wiring. • Two-part surface-mount design (reed switch + magnet) • Durable plastic housing • Available in Normally Closed (NC) or Normally Open (NO) versions • Compatible with burglar alarms, access control and home-automation systems

• Genuine, warranty-backed
• Countrywide delivery
• Real human support
