Dpdt Relay Wiring Diagram. Spdt relay dpdt relay relay is a electro mechanical switch used to control high power application through low power signal electronic circuits for an example a simple timer circuit working under 5v dc bias can not control high voltage light bulb by introducing relay component we can easily control light bulb. Fig 1 2 dpdt terminal diagram look at picture 1 1 and 1 2 it consists of two common input terminals c e and both mechanically tied together to operate in the same way.
See website configurator for additional wiring schematics. It has 2 terminals and 4 connectors and you can look at the dpdt relay as the equivalent of 2 single pole double throw spdt relays. This is how you wire a double pole double throw dpdt switch.
This is how you wire a double pole double throw dpdt switch.
See website configurator for additional wiring schematics. The dpdt relay double pole double throw is quite interesting and can be used in various scenarious including for changing the direction of a motor as you can see in the picture below. The 2 coil terminals is where the voltage is placed in order to energize the coil. The input supply always is given to the common terminal c and e only.
