SINGLE POLE DOUBLE THROW RELAY WIRING DIAGRAM
Single Pole Double Throw (SPDT) Relay Wiring Diagram
Single Pole Double Throw (SPDT) Relay Wiring Diagram This is the diagram below to learn all the pin terminals of a Single Pole Double Throw (SPDT) Relay: The 2 COIL terminals is where the voltage is placed in order to energize the coil.
How to Connect a Single Pole Double Throw (SPDT) Relay in
When the relay receives 12 volts of power, the relay's snaps from the NC position to the NO position. The red LED now shuts off and the green LED turns on. Related Resources.

SPST, SPDT, DPST, and DPDT Explained - Littelfuse
SP and DP refer to single pole and double pole, ST and DT refer to single throw and double throw. Pole refers to the number of circuits controlled by the switch: SP switches control only one electrical circuit. DP switches control two independent circuits (and act like two identical switches that are mechanically linked).
How to Wire a Single Throw Double Pole Switch | Hunker
A double pole single throw (DPST) switch controls the connections to two wires at once, where each wire only has one possible connection. In other words, it's like two simple switches controlled by a single actuator. The DPST switch often appears in circuit breakers, where it is used for 240-volt..
DPST Relay – Double Pole Single Throw – Circuit Wiring
The Double Pole Single Throw DPST relay is the equivalent of 2 SPST switches (NO Normally Open and NC Normaly Closed) and can be used to switch 2 different loads. We have 2 scenarios depending on the type of relay. without voltage on coil:
SPDT Relay - Single Pole Double Throw
The Single Pole Double Throw SPDT relay is quite useful in certain applications because of its internal configuration. It has one common terminal and 2 contacts in 2 different configurations: one can be Normally Closed and the other one is opened or it can be Normally Open and the other one closed. So basically you can see the SPDT relay as a way of switching between 2 circuits: when there is
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) 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.
DPST Relay - Double Pole Single Throw
The Double Pole Single Throw DPST relay is the equivalent of 2 SPST switches (NO Normally Open and NC Normaly Closed) and can be used to switch 2 different loads. We have 2 scenarios depending on the type of relay. without voltage on coil: with a NO the loads will be OFF because the current cannot flow
switches - Wiring a SPDT Relay - Electrical Engineering
Wiring a SPDT Relay. Ask Question 2 I added #'s to the pins in the diagram to help describe wiring. The bottom right is the center of the "pole" of the SPDT (Single Pole Double Throw) switch. The pole is always electrically connected to one of the two top pins. It's a little unclear, but I'm guessing the top left pin is NO (Normally
