SPST stands for Single-Pole, Single-Throw, and is a designation for the switch contact arrangement that has just two terminals. As the switch is thrown, these two terminals will be either open or closed depending on the position of the handle.

What is a SPST?

It is a single contact that can be either on or off. It has just two connections. The typical household light switch is a good example. SPST stands for Single Pole - Single Throw Single Pole = one contact Single Throw = on/off (as opposed to on/off/on, slow/fast/off, etc.)


Is it difficult to differentiate a SPST switch from a SPDT switch?

No it is not hard to tell them apart. A Single Pole Single Throw switch will go directly from the on position to the off position breaking the circuit. This is the type of switch that is used in homes for lighting control. A Single Pole Double Throw switch will usually have a stop indent which is the off position mid way through the throw. This is the switch that is used for a transfer switch when using a stand by generator in the system. The full up (on) position is usually connected to utility power. The full down (on) position is usually connected to the stand by generator.

What are the uses of spst and spdt switches?

SPST (Single Pole, Single Throw) switches are commonly used to control a single circuit, either turning it on or off. SPDT (Single Pole, Double Throw) switches can control two separate circuits or functions, allowing for the selection of one of two options. Both types of switches are used in various electronic and electrical applications to control power distribution and circuit function.
