A basic relay switch has a control circuit with an electromagnetic coil and a load circuit with contacts and a lever. When current flows into the relay switch  it moves through the coil and a magnetic field is created  which causes the lever in the load circuit to move between contacts  either turning the device on or off. In a normally open (NO) relay switch  when power is supplied to the relay  the load circuit is closed and the power source connected to the relay is turned on. In a normally closed (NC) relay switch  when power is supplied to the relay  the load circuit is open and the power source connected to the relay is turned off. In other types of relay switches  non-moving parts such as transistors or semiconductors can be used as the control circuit to operate the switching mechanism. Relay switches can be controlled with an external switch  such as a light switch  or they can be connected to an automatically switched power source  such as a car ignition. One relay can operate multiple switches  and multiple relays can be operated with a single switch  with each relay operating independently from the other relays in the system.Supco manufactures test instruments and replacement parts for heating  ventilation  air conditioning  and refrigeration systems. The company  founded in 1945  is headquartered in Allenwood  NJ.\u003c\/p\u003e","brand":"Supco","offers":[{"title":"Default Title","offer_id":44379821178989,"sku":"CANA-B004XS1ZT0","price":41.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0688\/1732\/2093\/files\/61cW7yWnDbL.jpg?v=1772877347","url":"https:\/\/www.dowise.store\/products\/supco-90340-general-purpose-switching-relay-24-v-coil-voltage-double-pole-double-throw-contacts-new","provider":"Dowise","version":"1.0","type":"link"}
