Abstract
A switching circuit for connection to a load and to a voltage source is provided. The switching circuit includes at least one switching device for switching on and off power to the load. A pulldown device is provided for shorting out the load thereby isolating the load from the voltage source; and a controller operable while the load is shorted to activate at least one of the switching devices at a time. The current passes through the activated switching device and is measurable to test whether the activated switching device is operating correctly.
