What does a push switch do in a circuit?
it starts a circuit by connecting the circuit and the initials are ptm and its a spdt switch
What does the on and off switch do on an electrical circuit?
When you turn It off it breaks the circuit. When it is turned on it closes the circuit. To have a light bulb turn on it need to have continuity. Hope that helps
When you turn on a television what is the electrical circuit?
The electrical circuit when turned on it is considered closed. By the same token when an electrical circuit is turned off the electrical circuit is considered open.
What things need a electrical circuit?
Electrical devices need an electrical circuit.
What job does a switch do in a circuit?
It opens and closes a circuit and it makes the bulb turn off and on and it completes a circuit when it is closed.
What a switch does in an electrical circuit?
opens and closes the circuit
Electrical device activated by a current that opens or closes another 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.

Is the key have anything to do with the car starting?
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.
What device opens and closes an electric circuit?
A switch is a device that is used to open and close an electrical circuit that is is connected into.

What is a electromechanically relay?
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.
What is the simple device that opens and closes an electrical unit called?
A device that opens and closes a circuit is called a switch.
What does an switch do in a circuit?
opens and closes the circuit
What is an electrical switch that opens and closes under the control of another electrical circuit?
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.
What is the part of the circuit that closes or opens the circuit?
The switch.
How is the compressor clutch engaged on the air con system?
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.
