Spst switches are thus very simple in nature.
Closed switch spst single pole single throw.
A 2 way changeover switch directs the flow of current to one of two routes according to its position.
A single pole double throw switch can serve a variety of functions in a circuit.
Switch with delayed opening.
A switch s throw count defines how many positions each of the switch s poles can be connected to.
For example if a switch has two throws each circuit pole in the switch can be connected to one of two.
One for the input and one for the output.
A basic on off switch that turns a single circuit on or off.
Spst single pole single throw.
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.
Below is an example of a circuit which utilizes a single pole single throw switch.

A four pole switch can separately control four different circuits.
When used with mains electricity this type of switch must be in the live wire but it is better to use a dpst switch to isolate both live and neutral.
A single pole single throw switch serves in circuits as on off switches.
The photograph shows a spst toggle switch.
When the switch is open the circuit is off.
So a switch with one pole can only influence one single circuit.
Switch with delayed opening and closing.
An on off switch allows current to flow only when it is in the closed on position.
When the switch is closed the circuit is on.
