Door Bell : A doorbell is a signaling device typically placed near a door to a building's entrance. When a visitor presses a button, the bell rings inside the building, alerting the occupant to the presence of the visitor. Although the first doorbells were mechanical, activated by pulling a cord connected to a bell, modern doorbells are electric, operated by a pushbutton switch. Modern doorbells often incorporate intercoms and miniature video cameras to increase security.
Bell Push Switches: These are essentially single pole switches with a spring mechanism. Bell switches allow a short burst of electric current when pushed and then revert to the off position, hence breaking the circuit. These switches are usually used for operating doorbells in homes and office, but also find use in certain industrial installations for quickly checking power status.
