Wire the new single pole switch.
Single pole single throw switch diagram.
This means it has one input terminal and two output terminals.
It can serve as an on off switch depending on how the circuit is wired.
When the switch is closed the circuit is on.
Single pole single throw spst switch circuit.
Double throw closes a circuit in the up or down position on 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.
Single throw closes a circuit at only one position.
Dpdt double pole double throw toggle.
Spst switches are thus very simple in nature.
A single pole single throw switch serves in circuits as on off switches.
The dpst switch for example has four terminals however is a double pole dp and not a four pole 4p 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.
A single pole double throw switch can serve a variety of functions in a circuit.
When the switch is open the circuit is off.
Inspect the end of each wire.
Look at the figure 1 2 the centre dotted line indicates that the dpdt switch is actually two spdt switches in one package.
Bend the end into a loop using the wire strippers or.
In other words it s like two simple switches controlled by a single actuator.
A double pole single throw dpst switch controls the connections to two wires at once where each wire only has one possible connection.
Below is an example of a circuit which utilizes a single pole single throw switch.
The center position is off.
