Single Pole Single Throw Switch Schematic

Sp switches control only one electrical circuit.

Single pole single throw switch schematic.

A single pole single throw switch serves in circuits as on off switches. The circuit symbol and a simple diagram representing the switch are shown and labelled. When the switch is closed the circuit is on. 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.

Spdt single pole double throw. This means it has one input terminal and two output terminals. 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.

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

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. This type of switch is sometimes called an a b switch because it lets. An spdt switch routes one input circuit to one of two output.

One for the input and one for the output. Two for incoming hots and two for outgoing hots. One for the input and one for the output. A single pole double throw switch can serve a variety of functions in a circuit.

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. A graphic illustrating an spst switch. It has four terminals.

Single pole single throw spst switch circuit. 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. A basic on off switch that turns a single circuit on or off.
