Single Pole Single Throw Switch Schematic

The circuit symbol and a simple diagram representing the switch are shown and labelled.

Single pole single throw switch schematic. An spst switch has two terminals. Sp and dp refer to single pole and double pole st and dt refer to single throw and double throw. A basic on off switch that turns a single circuit on or off. A double pole switch is what you need to control a 240 volt device because 240 volt circuits have two hot wires.

Spst single pole single throw. Sp switches control only one electrical circuit. Single pole single throw spst switch circuit. Two for incoming hots and two for outgoing hots.

Spst switches are thus very simple in nature. Below is an example of a circuit which utilizes a single pole single throw switch. A single pole double throw switch can serve a variety of functions in a circuit. One for the input and one for the output.

A graphic illustrating an spst switch. Spdt single pole double throw. An spdt switch routes one input circuit to one of two output. One for the input and one for the output.

An spdt switch routes one input circuit to one of two output circuits. A single pole single throw switch serves in circuits as on off switches. It has four terminals. A basic on off switch that turns a single circuit on or off.

Pole refers to the number of circuits controlled by the switch. When the switch is open the circuit is off. This means it has one input terminal and two output terminals. Dp switches control two independent circuits and act like two identical switches that are mechanically linked.

When the switch is closed the circuit is on. This type of switch is sometimes called an a b switch because it lets. Spdt single pole double throw. The difference between a single and double pole switch is that the latter controls two circuits at the same time.
