Wire the new single pole switch.
Single pole single throw switch diagram.
The dpst switch often appears in circuit breakers where it is used for 240 volt circuits with each pole carrying 120 volts.
Look at the figure 1 2 the centre dotted line indicates that the dpdt switch is actually two spdt switches in one package.
Spst switches are thus very simple in nature.
A double pole single throw dpst switch controls the connections to two wires at once where each wire only has one possible connection.
The center position is off.
A single pole single throw switch serves in circuits as on off switches.
Inspect the end of each wire.
A single pole double throw switch can serve a variety of functions in a circuit.
A double pole double throw toggle switch is a combination of two individual spdt single pole double throw switches connected in the single assembly.
If the wire end is in poor condition trim off the bare end then strip about 3 4 inch of insulation using wire strippers.
This means it has one input terminal and two output terminals.
In other words it s like two simple switches controlled by a single actuator.
Single pole single throw spst switch circuit.
It can serve as an on off switch depending on how the circuit is wired.
Dpdt double pole double throw toggle.
Single throw closes a circuit at only one position.
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.
When the switch is open the circuit is off.
Below is an example of a circuit which utilizes a single pole single throw switch.
When the switch is closed the circuit is on.
A double throw switch can also have a center position such as on off on.
