Circuit breaker or switch
Timer relays are used in control circuitry. There are two main types, an (off delay) and an (on delay). If you want one device to turn off before the timer controlled device then you would use an off delay timer. If you want one device to turn on before the timer controlled device then you would use an on delay timer. When the timer is energized this starts the timer circuit in the relay to time out.
A switch is a device that can be used to turn a circuit off and on. When the switch is in the "on" position, current can flow through the circuit, and when it is in the "off" position, the circuit is broken and current cannot pass through.
An electric circuit control device is used to regulate and manage the flow of electricity within a circuit. It can turn the circuit on or off, adjust voltage levels, and protect against overloads or short circuits. These devices help ensure safe and efficient operation of electrical equipment.
To de-energize a circuit, the voltage has to be cut off at the source. This is usually done with a disconnect switch which is located just before the circuit's load. Turning off the breaker on a distribution panel will de-energize the circuit it is feeding. To make sure that the voltage can not be turned back on when work is being done on the circuit, the switch or breaker must have a lock off device to prevent the circuit from being turned on, except by the person that locked the circuit off.
To de-energize an electrical circuit, you should turn off the power source by switching off the circuit breaker or removing the fuse associated with that circuit. Additionally, you can unplug the device or equipment from the power outlet to ensure that the circuit is not energized. Always use proper safety measures and equipment when working with electrical circuits to prevent accidents and injuries.
It is true that a switch is used to open and close a circut.
Electricity only works when it can flow all the way around a loop called a circuit. Turning off a switch breaks the circuit, stopping the flow and turning electrical things off. Turning a switch on joins the circuit and makes them work again.
A series circuit. Turning off the light interrupted the only path for electricity to the hair dryer.
You can start an electric circuit by closing the circuit, typically by turning a switch on. You can stop an electric circuit by opening the circuit, usually by turning a switch off or disconnecting a wire.

False. A device that is used to open the circuit when the current flow is too great is a circuit breaker or fuse.A disconnect switch is a manual device that isolates or turns off the load.

A safety device that uses an electromagnet to shut off the circuit is called a contactor.
Rapidly switching a device or light source on and off is known as "toggling." This can be done manually or controlled automatically through a circuit or software program. Toggling is commonly used in electronics and automation systems to achieve specific functions or behaviors.

If a circuit has no switch then it remains 'on' permanently. If you desire to open or close a circuit, for turning on or turning off a light for example, you need some kind of switch.
