Newer designs of time-delay relays use electronic circuits with resistor-capacitor (RC) networks to generate a time delay, then energize a normal (instantaneous) electromechanical relay coil with the electronic circuit’s output. The electronic-timer relays are more versatile than the older, mechanical models, and less prone to failure.

How to Draw Electrical Diagrams and Wiring Diagrams

 · A circuit board is a piece of insulation that is threaded with conductive wires and similar components. When a power supply introduces an electrical charge to the board, it is distributed along these wires to different components in a variety of ways. This lets the board control how these components are activated and charged during the use of an electrical device.
