Abstract
A control circuit for a heating pad. The control circuit includes a two-pole, four-position slide switch. The four positions of the two-pole, four-position slide switch include off and three different heat settings of the heating pad. The control circuit also includes three heat setting indicators that are alternatively illuminated when the switch is in the three different heat settings. Diodes are used to direct electrical currents through the indicators as appropriate. The diodes and the two-pole, four-position slide switch are arranged so that current may be appropriately flow through, or may be blocked from flowing through, the indicators when the two-pole, four-position slide switch is in each of the three heating settings.
