That function was traditionally implemented in the form of a mechanical device
known as a "switch".
The practice became so firmly embedded in the art and science of electricity
that the word became the generic term for any device that could perform
any similar function, so that now we have "switching transistors", integrated
"CMOS switches", and even central office telephone-circuit "switches".

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 is the part of a circuit the closes or opens the 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
What is A small piece of plastic-encased metal that closes a circuit?
fuse
Which switch opens the circuit on a tv?
The power on switch
Will overcharging cellphone cause electrical short circuit?
No, overcharging cellphone will not cause an electrical short circuit.
It closes the electrical circuit.?
The definition of a switch is a device that closes and opens an electrical circuit.
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.
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 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 an switch do in a circuit?
opens and closes the circuit
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 part of the circuit that closes or opens the circuit?
The switch.
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 is a part of s circuit that opens and closes the circuit?
A switch.
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 part in an electric circuit opens and closes the circuit?
A switch, switching transistor, or circuit breaker usually does.
