Single Pole Single Throw Switch Diagram

A double throw switch can also have a center position such as on off on.

Single pole single throw switch diagram. It can serve as an on off switch depending on how the circuit is wired. 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 spdt switch is a switch that only has a single input and can connect to and switch between 2 outputs. Spst switches are thus very simple in nature.

A single pole single throw switch serves in circuits as on off switches. A double pole single throw dpst switch controls the connections to two wires at once where each wire only has one possible connection. 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.

If the wire end is in poor condition trim off the bare end then strip about 3 4 inch of insulation using wire strippers. The dpst switch often appears in circuit breakers where it is used for 240 volt circuits with each pole carrying 120 volts. This means it has one input terminal and two output terminals. The center position is off.

Wire the new single pole switch. Dpdt double pole double throw toggle. When the switch is closed the circuit is on. In other words it s like two simple switches controlled by a single actuator.

A double pole double throw toggle switch is a combination of two individual spdt single pole double throw switches connected in the single assembly. When the switch is open the circuit is off. Bend the end into a loop using the wire strippers or. The dpst switch for example has four terminals however is a double pole dp and not a four pole 4p switch.

Below is an example of a circuit which utilizes a single pole single throw switch. Double throw closes a circuit in the up or down position on on.
