Velleman HAA26: Flush Mount Magnetic Switch

Magnetic switches like the Velleman HAA26 are perfect for hands free switching or alarm system applications. One portion of this two piece cylindrical switch is powered and the other is not. The relay is normally closed (NC), which means that as long as the two sections of the HAA26 are in alignment, the relay is closed and the electrical circuit is complete. If the Velleman HAA26 were mounted in a door & door frame and the door opened, the two sections would no longer be lined up and the relay would open interrupting the circuit.

  • Cable length: 2" x 10.8"
