Limit Switch.

Float Switches.

In the simplest case, a switch has two conductive pieces, often metal, called contacts, connected to an external circuit, that touch to complete (make) the circuit, and separate to open (break) the circuit

Two basic categories of electrical switches are manual and automatic.

A switch that opens and closes an electric circuit is typically electromechanical in nature. This, correspondingly, stops and starts the flow of electric current.

A mechanical handle, lever, or rocking mechanism is used to manually activate (or push up or down) a toggle switch. These are frequently employed as switches for lighting.

An electrically controlled switch is a relay. It is made up of a set of working contact terminals and a set of input terminals for one or more control signals. Any number of connections in different contact configurations, such as making contacts, breaking contacts, or combinations of both, may be included on the switch.

Therefore, electrical switches can be divided into two fundamental categories: manual and automatic.
