How to Connect a Single Pole Double Throw (SPDT) Relay in ... Now that we know what each terminal pin represents, we now wire it to a circuit for it to do a real world function. We're going to connect a single pole double throw relay to a circuit to light up a LED. When the relay isn't powered, the red LED is lit and stays on. When the relay is powered, the red LED shuts off and the green LED lights up. Single Pole Double Throw (SPDT), Single Pole Single Throw ... SPST Relay (Single Pole Single Throw Relay) an electromagnetic switch, consist of a coil (terminals 85 & 86), 1 common terminal (30), and one normally open terminal (87).It does not have a normally closed terminal like the SPDT relay, but may be used in place of SPDT relays in all diagrams shown on this site where terminal 87a is not used. Wiring Diagrams relaypros This page demonstrates several simple ways to wire a relay for various applications. Diagrams will show how multiple relays, one relay or another or just one relay can control your device. All examples shown are for SPDT (single Pole Double Throw) relays which includes any of the 5, 10 or 20 amp relays on this site. Single Pole Single Throw (SPST) Relay Wiring Diagram Single Pole Single Throw (SPST) Relay Wiring Diagram This is the diagram below to learn all the pin terminals of a Single Pole Single Throw (SPST) Relay: The 2 COIL terminals is where the voltage is placed in order to energize the coil. How to Wire a 12V Relay | It Still Runs Most 12 volt relays operate accessories in a motor vehicle. Applying a small amount, as low as .2 amps of current to the relay coil closes contacts to feed power to an accessory that requires more current to operate, usually over 20 amps.
