Answer:
The small circular thing used to activate a machine is named as switch.
Explanation:
A machine can be switched on and off by pressing a button termed as switch. The switch is a junction point which can cut off a circuit when it is switch off and it can create a circuit when the switch is on.
n ON mode, the switch helps in completing the circuit so that the current can flow without any disturbance which in turn helps in switching on the machine and the machine will be working until it is switched off.
Again pressing the same switch will lead to break the circuit leading to switching off of the machine, as there will be not current flow in the circuit.
