Single Pole Single Throw Switch Schematic

An spdt switch routes one input circuit to one of two output.

Single pole single throw switch schematic.

Sp switches control only one electrical circuit. A single pole double throw switch can serve a variety of functions in a circuit. Below is an example of a circuit which utilizes a single pole single throw switch. 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. Spst single pole single throw. The difference between a single and double pole switch is that the latter controls two circuits at the same time. A single pole single throw switch serves in circuits as on off switches.

An spst switch has two terminals. When the switch is open the circuit is off. Spst single pole single throw. When the switch is closed the circuit is on.

Single pole single throw spst switch circuit. This means it has one input terminal and two output terminals. Spst switches are thus very simple in nature. A graphic illustrating an spst switch.

It has four terminals. This type of switch is sometimes called an a b switch because it lets. Spdt single pole double throw. Pole refers to the number of circuits controlled by the switch.

An spst switch has two terminals. 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. Sp and dp refer to single pole and double pole st and dt refer to single throw and double throw. One for the input and one for the output.

Two for incoming hots and two for outgoing hots. The circuit symbol and a simple diagram representing the switch are shown and labelled. A basic on off switch that turns a single circuit on or off. An spdt switch routes one input circuit to one of two output circuits.
