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...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. Place the relay's rated coil voltage on these terminals. The polarity of the voltage does not matter.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 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.

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 ...SPST, SPDT, and DPDT Switches Demystified SPST
SPST, SPDT, and DPDT Switches Demystified A Single Pole Single Throw toggle switch connects or disconnects one terminal either to or from another. It is the simplest switch. I assure you that 99.99% of all toggle switches work as I explain below. The mechnical parts inside are designed to connect the terminals just as I explain here.Switch
