Wiring a rocker switch isn’t complicated once you understand the logic behind it. Every connection serves a purpose, and when ...

ITHACA, N.Y. -- Cornell University researchers have demonstrated for the first time a device that allows one low-powered beam of light to switch another on and off on silicon, a key component for ...

In the 120V circuits of homes and offices, the grounded conductor is the same as the neutral. Typically, when wiring a switch for a 120V load (e.g., a light) only one wire comes to the switch and only ...

Over the years, various power-off circuits have been published. However, the circuit proposed here is very simple and has excellent characteristics. It features a fast power-off transition, with only ...

Applications for using a single pushbutton to advance a circuit to its next logical state are legion. Typically, there are just “on” and “off” states, but there can be more. The heart of the circuit ...
