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 – ...

If you are an RC modeller, then this circuit is for you! The compact RC Switch let you turn something on and off from a regular R/C channel. The device is powered entirely by the receiver, drawing ...

The requirements of Art. 404 apply to all types of switches including snap (toggle) switches, dimmer switches, fan switches, knife switches, circuit breakers, occupancy sensors, and automatic switches ...

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 ...

As electronics engineer I have a mental collection of circuits that I’ve gathered over the years, much like a mechanic collects specialized tools as they work. All engineers do this and the tools in ...

Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important for ...

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 ...

Every month we receive a substantial number of technical questions, many of which deal with electrical problems. Recently we were in Texas visiting the folks at Painless Performance and had the ...

Switch-mode power supplies (SMPS) continue to replace linear-regulator types in a host of applications. As the need for more efficient electronics accelerates and as a result of their size, weight, ...
