Abstract
An electrical circuit for use in a contact lens care unit for disinfecting lenses includes two thermostats one of which is manually set to electrically energize a heating device for disinfecting lenses and an indicator element for providing visible representation of the operational state of the unit. The second of which thermostats automatically energizes to provide a parallel electrical energizing path to the indicator for a period of time after the first thermostat automatically deenergizes the heating device. The indicator is thereby continually energized throughout a complete contact lens care cycle to provide prominent representation of the operational state of the unit.
