Abstract
A switch assembly configured to determine when input received from a switch is caused by proper actuation of the switch and should be accepted, or is caused instead by a fault in the switch or in the intervening circuitry and should be ignored and/or reported. The switch assembly optionally includes a logic circuit that is electrically connected to the switch. The logic circuit may provide power to the switch, for example, as a time varying signal, which may then be presented to the logic circuit as input when the switch is properly actuated. The logic circuit may then compare the input from the switch with the signal sent to the switch to determine if a fault is present, or if the switch is operating properly.
