Here is a great collection of touch switch circuits. A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor. Simple touch switch circuit with 4011 – ...

This halogen light switch circuit works only for dc halogen lamps. Halogen lamps give a good light and have an excellent eficiency. In this halogen switch circuit we use a FET transistor because the ...

Limit switches detect and are controlled by the motion or presence of an object. Switches are electrical devices used to break electrical circuits. Limit switches are essentially switches that can be ...

Circuit breakers are automatic electrical switches designed to interrupt current flow in the event of an overload or short circuit. Electrical circuits can experience several conditions which pose ...

Integrated circuit technologies are enabling intelligent, chip-based, optical packet switch matrices. Rapid real-time re-configurability at the photonic layer using integrated circuit technologies is ...

Don’t put up with old three-way light switches like this. Swap them out for something new and improved. Archaic light switches might as well be from the stone age. All they do is turn a light on and ...

Water is usually something you’d want to keep away from electronic circuits, but engineers in Germany have now developed a new concept for water-based switches that are much faster than current ...
