Electrical switch assembly

Abstract

An electrical switch assembly is suitable for use in an electrical appliance requiring a descaling procedure after a predetermined number of operating cycles. The switch assembly has a first switch and a second switch. The first switch has a housing, a switch mechanism, contact terminals for the switch mechanism extending from the housing, a microprocessor disposed within the housing and arranged to monitor the status of the switch, an interface for the microprocessor accessible from outside the housing, and an actuator for manually operating the switch mechanism. The second switch provides a signal to the microprocessor indicative of a selected number of operating cycles between descaling procedures, and the microprocessor indicates that descaling is required when the preselected number of operating cycles is reached.
