Mains switch for domestic appliance, e.g. washing machine, includes relay to provide complete disconnection from mains at end of program

摘要

The appliance controller (4) automatically activates the mains switch (1) at the end of a program so that the appliance is completely disconnected from the mains supply, e.g. by a electro-mechanical or mechanical link. Some electrical loads (5) can be supplied in parallel through another switch operated by a relay (2) that opens the switch when no current is being consumed.
