  • Interlock switch circuit with single fault detection
    Patent number: 9188646
    Abstract: A testing system to test safety interlock switches to ensure that they are operating normally comprising a test loop circuit 16 which connects in series a plurality of safety switches 2, the test loop circuit 16 is adapted to open the switches 2 outputs if broken, the testing system further comprising a diagnostic means 18 which checks each switch to ensure it is operating normally when the test loop circuit 16 is broken. The test loop circuit 16 may be broken when a single switch 2 is activated to open its safety output.

  • Safety switch with dual anti-tamper
    Patent number: 9177735
    Abstract: A safety interlock switch with coded interlocking to provide tamper resistance, the coded interlocking having two differently coded technologies 8,10; 16,18. In a preferred embodiment one technology is mechanical in the form of a coded-cam system operated by a coded-tongue 8, the other is electronic comprising a non-contact coded RFID sensor 16,18, and wherein the switch is only enabled when the two different codes have been correctly applied.
