Single Pole Single Throw

Single pole single throw relays provide the most straightforward approach to isolation.

Single pole single throw.

Single pole changeover or single pole centre off or single pole triple throw similar to spdt. Hence spst uses to control a single circuit at a time. Choose from our selection of single pole single throw switches in a wide range of styles and sizes. A single pole single throw spst switch is a switch that only has a single input and can connect only to one output.

Pole refers to the number of circuits controlled by the switch. Sp switches control only one electrical circuit. A single stationary contact and a moveable contact furnish a simple on off configuration. Dp switches control two independent circuits and act like two identical switches that are mechanically linked.

Forms include normally open no and normally closed nc. Sp and dp refer to single pole and double pole st and dt refer to single throw and double throw. Spst circuit diagram construction of spst. Normally open relays provide voltage isolation until coil power is applied.

A simple break before make changeover switch. This means it only has one input terminal and only one output terminal. Construction front the switch has two terminal and contact portion is made up of silver alloy to withstand the high circuit breaking current. In our single pole single throw switch you can get single output.

It will be separated by the minimal. When the switch is closed the circuit is on. In stock and ready to ship.
