Single Pole Single Throw Switch Diagram

Wire the new single pole switch.

Single pole single throw switch diagram.

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 double throw switch can also have a center position such as on off on. A single pole double throw spdt switch is a switch that only has a single input and can connect to and switch between 2 outputs. Single pole single throw spst switch circuit.

Double throw closes a circuit in the up or down position on on. Below is an example of a circuit which utilizes a single pole single throw switch. A single pole single throw switch serves in circuits as on off switches. In other words it s like two simple switches controlled by a single actuator.

If the wire end is in poor condition trim off the bare end then strip about 3 4 inch of insulation using wire strippers. Spst switches are thus very simple in nature. The dpst switch for example has four terminals however is a double pole dp and not a four pole 4p switch. It should have about 1 2 inch of bare wire at the end and should be formed into a hook like loop.

This means it has one input terminal and two output terminals. Dpdt double pole double throw toggle. Bend the end into a loop using the wire strippers or. Inspect the end of each wire.

It can serve as an on off switch depending on how the circuit is wired. The dpst switch often appears in circuit breakers where it is used for 240 volt circuits with each pole carrying 120 volts. When the switch is open the circuit is off. Look at the figure 1 2 the centre dotted line indicates that the dpdt switch is actually two spdt switches in one package.

When the switch is closed the circuit is on. A double pole single throw dpst switch controls the connections to two wires at once where each wire only has one possible connection.
