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.


When you turn off the switch of a blow dryer does that create a series circuit?

No, it opens the circuit so that no current flows.


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 opens or closes an electrical circuit?

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


What determines whether a pressure switch opens or closes on a rise of pressure?

A pressure switch opens or closes in response to a predefined pressure setpoint, which is determined by the internal mechanism of the switch. When the pressure in the system rises and exceeds this setpoint, the switch activates, either opening or closing an electrical circuit. The specific action—whether it opens or closes—depends on the design of the switch, which can be configured as normally open (NO) or normally closed (NC). Additionally, the pressure hysteresis settings can influence the exact point at which the switch resets after activation.

What does a push-to-make switch do in a circuit?

A push-to-make switch completes the circuit and allows electricity to flow through when the switch is pressed or engaged. When the switch is released, the circuit opens, interrupting the flow of electricity.
