Single Pole Single Throw Switch Diagram

Below is an example of a circuit which utilizes a single pole single throw switch.

Single pole single throw switch diagram.

A double pole single throw dpst switch controls the connections to two wires at once where each wire only has one possible connection. A double throw switch can also have a center position such as on off on. A double pole double throw toggle switch is a combination of two individual spdt single pole double throw switches connected in the single assembly. A single pole double throw switch can serve a variety of functions in a circuit.

Look at the figure 1 2 the centre dotted line indicates that the dpdt switch is actually two spdt switches in one package. Dpdt double pole double throw toggle. Wire the new single pole switch. The dpst switch often appears in circuit breakers where it is used for 240 volt circuits with each pole carrying 120 volts.

It should have about 1 2 inch of bare wire at the end and should be formed into a hook like loop. Double throw closes a circuit in the up or down position on on. Inspect the end of each wire. In other words it s like two simple switches controlled by a single actuator.

The center position is off. The dpst switch for example has four terminals however is a double pole dp and not a four pole 4p switch. When the switch is open the circuit is off. Single pole single throw spst switch circuit.

Spst switches are thus very simple in nature. It can serve as an on off switch depending on how the circuit is wired. A single pole single throw switch serves in circuits as on off switches. When the switch is closed the circuit is on.

If the wire end is in poor condition trim off the bare end then strip about 3 4 inch of insulation using wire strippers. Bend the end into a loop using the wire strippers or.
