Unit - Relays 7


      Relays are used in refrigerators, washing machines and dishwashers in the home as well as heating and air-conditioning controls. Elaborate relay designs are used to protect against problems with the electrical power distribution grid. These problems can include brownout, blackout and total interruption of your electrical service.
