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 – ...

A simple and inexpensive electronic circuit uses a low-cost pushbutton switch to toggle the electrical power on and off. The circuit replaces a more costly and bulky push-push mechanical switch. The ...

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 ...

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 ...

Mechanical switches can be noisy, generating multiple transient pulses that may cause faulty operation of fast digital circuits. In this design, a pair of MOSFETs are ...

Electrical circuits have always been a mystery to me. Those tiny components that look like Chiclets or jewelry beads somehow ...

The circuit of Figure 1 provides a "diode-OR" function for applications that must switch automatically between the main and backup supply voltages. Such applications include battery-backed memory ...

What if the next generation of disposable electronics—the sensors in your food packaging, the diagnostic strips in a medical ...
