Abstract
A system controller such as a microprocessor receives voltage signals produced from a resistor identifying the functional or nonfunctional operating state of a power switch which controls the amount of power provided to a load in an electrical system. The resistor is also used to provide voltage signals representing the temperature of a heating element of the type used in heating pads and heating blankets. The functional or nonfunctional operating state of a safety switch in a safety circuit capable of blowing a fuse and cutting power to the load is periodically tested to ensure the safety of the electrical system.
