THE 555 INTEGRATED CIRCUIT (IC) TIMER
... The circuit operates as follows. When the On/Off switch is closed, the initially uncharged capacitor C will charge towards the 12 volts provided by the Primary Power battery via the potentiometer RV1. The OUTPUT of the 555 will be HIGH (12 volts) and the relay coil will not be energized until the vo ...

... As the switch closes, the reluctance varies, concentrating the magnetic field inside the switch and enabling the switch to stay closed Brainstorm Question: If you were to slowly ramp up the power supply, what would happen if the turn-on voltage and the turn-off voltage were exactly the same? ...

The filament-voltage is typically 5.3V measured between pins 1 and 5 on the 3-500Z sockets when the amplifier is operated from 120V/240V, 60Hz. 5.3V exceeds Eimac®'s maximum filament-voltage rating. According to Eimac®, each 3% increase in filament- ...

Switch
In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another.The mechanism of a switch may be operated directly by a human operator to control a circuit (for example, a light switch or a keyboard button), may be operated by a moving object such as a door-operated switch, or may be operated by some sensing element for pressure, temperature or flow. A relay is a switch that is operated by electricity. Switches are made to handle a wide range of voltages and currents; very large switches may be used to isolate high-voltage circuits in electrical substations.
