  • More Info


    Normally Open 3/4-Inch Magnetic Contacts are ideal for signaling applications where the contacts are open when the magnet and sensor are together. Use this switch for triggering a Powerflash Module to send an ON signal when a door or window is opened.

    Mount the magnet on the door or window so that the two are in contact with each other when the door or window is closed. Slotted mounting holes make it easy to adjust the distance between the magnet and the sensor.

    3/4-Inch Magnetic Contacts, Normally Closed are ideal for security system where the contacts are closed when the magnet and sensor are together.
