Single Pole Single Throw Switch Schematic

It has four terminals.

Single pole single throw switch schematic.

Single pole single throw spst switch circuit. An spdt switch routes one input circuit to one of two output. Spst single pole single throw. A double pole switch is what you need to control a 240 volt device because 240 volt circuits have two hot wires.

This type of switch is sometimes called an a b switch because it lets. One for the input and one for the output. An spst switch has two terminals. A basic on off switch that turns a single circuit on or off.

When the switch is open the circuit is off. Sp switches control only one electrical circuit. Below is an example of a circuit which utilizes a single pole single throw switch. Sp and dp refer to single pole and double pole st and dt refer to single throw and double throw.

Two for incoming hots and two for outgoing hots. Spst switches are thus very simple in nature. An spdt switch routes one input circuit to one of two output circuits. Spdt single pole double throw.

One for the input and one for the output. A basic on off switch that turns a single circuit on or off. Dp switches control two independent circuits and act like two identical switches that are mechanically linked. This means it has one input terminal and two output terminals.

When the switch is closed the circuit is on. The circuit symbol and a simple diagram representing the switch are shown and labelled. A single pole single throw switch serves in circuits as on off switches. The difference between a single and double pole switch is that the latter controls two circuits at the same time.

Spst single pole single throw. Spdt single pole double throw. An spst switch has two terminals. A single pole double throw switch can serve a variety of functions in a circuit.
