The definition of a switch is a device that closes and opens an electrical circuit.
Generally a circuit breaker (like a light switch) But I guess you could use a resistor of the right resistance If you are talking about the circuit breaker there is an electromagnetic coil in it which get magnetized on a specific amount of current and breaks the circuit
A push switch is an electronic component that completes or breaks an electrical circuit when it is pressed. Pressing the switch physically moves its internal contacts to connect or disconnect the circuit, allowing current to flow or stop flowing. This type of switch is commonly used to turn devices on or off.
The on and off switch controls the flow of electricity in the circuit. When the switch is on, it completes the circuit and allows electricity to flow through. When the switch is off, it breaks the circuit and stops the flow of electricity.
The load that is connected to the circuit is what draws the power of the electrical circuit.
By definition an electrical circuit is a route or path that starts and finishes at the same place. So there is no part of an electrical circuit that is not necessary, because if there were it would not be an electrical circuit.An electrical circuit needs a power source. Conductors to transmit the voltage from the power source to the load. The final component of the electrical circuit is the load that you want to energize.If you remove any of the components there will be an open circuit and the load will be impossible to operate.
opens and closes the circuit
An electrical device activated by a current that opens or closes another circuit is called a relay. A contactor also falls into this category.
When the key is turned on, it closes an electrical circuit. That closes another electrical circuit which makes and electromagnet work. The electromagnet closes a circuit between the battery and the starter. That starts the car. So the key does not actually do any work to start the car but it tells the various circuits to get busy and start the car.
A switch is a device that is used to open and close an electrical circuit that is is connected into.
A relay is an electronic switching device that opens or closes a circuit. An electromechanical relay would be one that is opereated remotely using an electrical circuit that mechanically operated the relay, which in turn opens/closes the second ciruit.

If it is a physical switch, this is called a "relay" or a "contactor". If it is a semiconductor device, it is typically a triac, SCR or a thyristor.
The switch.
When not engaged, the wheel spins freely. When the low pressure switch closes, it closes the electrical circuit to the compressor clutch. This actuates an electromagnet, which pulls the clutch in to engage it.
