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.

Pole refers to the number of circuits controlled by the switch. An spst switch has two terminals. 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.

Sp switches control only one electrical circuit. Sp and dp refer to single pole and double pole st and dt refer to single throw and double throw. A single pole single throw switch serves in circuits as on off switches. Dp switches control two independent circuits and act like two identical switches that are mechanically linked.

When the switch is open the circuit is off. Spdt single pole double throw. Two for incoming hots and two for outgoing hots. A double pole switch is what you need to control a 240 volt device because 240 volt circuits have two hot wires.

This means it has one input terminal and two output terminals. One for the input and one for the output. Spst switches are thus very simple in nature. Spdt single pole double throw.

A basic on off switch that turns a single circuit on or off. Below is an example of a circuit which utilizes a single pole single throw switch. Spst single pole single throw. One for the input and one for the output.

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. This type of switch is sometimes called an a b switch because it lets. An spst switch has two terminals. Single pole single throw spst switch circuit.

When the switch is closed the circuit is on. An spdt switch routes one input circuit to one of two output circuits. The circuit symbol and a simple diagram representing the switch are shown and labelled. It has four terminals.
