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 ...

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 ...

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 ...

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 ...

Imagine a device where the interface isn't just functional but also sleek and integrated, handling complex commands with a simple touch. This is the promise of membrane switches, a technology that has ...

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 ...
