Single Pole Single Throw Switch Schematic

A single pole double throw switch can serve a variety of functions in a circuit.

Single pole single throw switch schematic.

A single pole single throw switch serves in circuits as on off switches. 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 single pole single throw. It has four terminals.

Two for incoming hots and two for outgoing hots. A basic on off switch that turns a single circuit on or off. 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.

Dp switches control two independent circuits and act like two identical switches that are mechanically linked. 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. When the switch is open the circuit is off.

A graphic illustrating an spst switch. An spdt switch routes one input circuit to one of two output. Below is an example of a circuit which utilizes a single pole single throw switch. This type of switch is sometimes called an a b switch because it lets.

Single pole single throw spst switch circuit. An spst switch has two terminals. Sp switches control only one electrical circuit. This means it has one input terminal and two output terminals.

A basic on off switch that turns a single circuit on or off. When the switch is closed the circuit is on. One for the input and one for the output. An spdt switch routes one input circuit to one of two output circuits.

Sp and dp refer to single pole and double pole st and dt refer to single throw and double throw. Spst switches are thus very simple in nature. Pole refers to the number of circuits controlled by the switch. One for the input and one for the output.
