This is a very simple touch light switch circuit that uses the 4011 IC, one transistor and a relay. The C1 capacitor stores the switching state at a certain time and is charged or discharged according ...

This relay-powered flashlight is definitely one of them. It has been named RattleGen by its creator [Berto], who apparently often makes simple hacks used in his everyday life (have a look at his ...

This circuit ... wire a relay switch to pass power to your system with no power loss. D 2 clamps inductive kicks from the relay coil. Figure 4 With reversed input voltage, the relay switch engages, ...

An RC circuit ... an energized relay coil will maintain contact closure even after the driving voltage is reduced somewhat. For many years, we have been employing a very simple approach to reduce ...

These are installed so that the relay contacts are closed when the lights are off. The 1N4005 diodes have higher reverse-voltage and forward-current ratings than this circuit requires, but because ...

light-duty switch to control our 30-amp fan through this relay and we've eliminated a long length of large wire that would likely produce a measurable voltage drop across the circuit. Instead ...

How to create a zero-crossing relay driver with a simple external circuit ... It often involves an ac load, such as a fan, light, amplifier circuit, or a smart meter. 1. This schematic highlights ...

A simple circuit includes a safety interlock ... 1 and 2 are typically a relay with force guided contacts. When a safety interlock, light curtain, or e-stop switch opens a circuit, the MPCE ...
