This intelligent electronic lock circuit is built using transistors only. To open this electronic lock, one has to press tactile switches S1 through S4 sequentially. For deception you may annotate ...

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 ...

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 ...

I know, I know—discussing the subject of a relay-based sequence switch in the age of omnipresent microprocessors seems to be a waste of time. After all, relays have been in use for many years. Is it ...

Electromechanical components including pushbutton switches, rocker switches, and illuminated tact switch buttons for power circuits and interfaces by Marquardt are available from TME. The components ...

A power adapter for a car car allows you to run everyday devices like handheld computers, televisions, video cameras, and even other power-hungry electrical appliances like refrigerators, hair dryers, ...

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 ...
