An infinite control can be used in lieu of the standard on/off toggle switch. It is different than an on/off toggle switch and is used when the operator would like to manually adjust the heat output from full wattage down to any desired level. It is considered a timing device that turns power on and off, unlike a thermostat which senses temperature and adjusts accordingly. The maximum amperage that an infinite control can handle is 12.2 amps. Since a toggle switch can handle 15 amps, an infinite control cannot always be field retrofitted in place of a toggle.
