QBAR switches are solid-state, 3 terminal, normally closed (NC), non-isolated devices. Reliable and cost-effective, they boast:

  • no power supply needed
  • simplified control wiring
  • "fail safe" over a wide range of system failure conditions
  • much lower control/input power requirement than electromechanical or
    optoelectronic (solid state) relays
  • "zeroize" peripherals and PCMCIA modules
  • fewer PCB jumpers
