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 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 ...

Any X-Y switch matrix can be considered with this circuit, which simplifies decoding of the common 4x4 keypad matrix and eliminates having to scan rows or columns. Using eight digital inputs, this ...

If you want to easily control the power in a circuit, you’ll probably reach for the classic toggle switch. While there’s certainly nothing wrong with that, physical toggles are a bit dated at this ...

There are standard designations and symbols that describe how electrical contacts work in specific scenarios. These designations spell out the number of contacts and how they behave during operation.

This video explains what transistors are and how they function as electronic switches and amplifiers. As a core component of ...

Automotive applications need “smarter” drivers for their switches, which handle loads ranging from a fraction of an ampere to several amperes. Not only are these smart chips costly, but many times, ...
