Mechanical switches play an important role in many microcontroller and microprocessor applications. These types of switches are simple, inexpensive, and easy to install. But, the perceived simplicity ...

When a mechanical contact, such as pushbutton, switch, user-interface button, limit switch, relay, or contactor contact, is opened or closed, the contact seldom demonstrates a clean transition from ...

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 ...
