What is the function of the contact screw in the working of electric door bell?

Answer 1

The contact screw in an electric doorbell serves as a point of contact for the circuit to be completed when the button is pressed. When the button is pushed, the contact screw connects the circuit, allowing electricity to flow through the doorbell mechanism, which in turn activates the chime or buzzer. The contact screw plays a crucial role in the functioning of the electric doorbell by facilitating the transmission of electrical current to produce the desired audible alert.
