The circuit in the figure shows a low-cost solution based on a transistor switch (Q1). The transistor is off under normal conditions, when the differential amplifier built around U1 amplifies the ...

Basic Load Switch A load switch is comprised of two main elements – the pass transistor and the on/off control segment. The pass transistor is most commonly a P-channel or N-channel MOSFET that passes ...

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 ...

A very simple but highly efficient combination lock circuit is shown in the figure. Any type of on/off switches can be used, varying from commercially available inexpensive types ...

Q1 is a simple PNP transistor acting as a pull-down switch until C1 charges and switches off Q1. That should spin up the SATA drive and then surrender pin 11 for drive activity usage. Is this ...

A transistor acts like a switch in an electrical circuit: a voltage at the transistor’s ‘gate’ terminal allows current to flow through a semiconductor inside the device.

Transistors are simple on/off switches. Computers are made of many millions of these switches. And to program a cell, you need a biological version.

In theory, the hundreds of photons, controlled by the triggering photon, could fan out and switch off hundreds of other transistors in an optical circuit.

You know them, you love them, you take them for granted – they are single push button on/off switches. As [Dino] explains in the most recent episode of his Hack a Week series, they are typica… ...
