A touch switch is a type of switch that only has to be touched by an object to operate. It is used in many lamps and wall switches that have a metal exterior as well as on public computer terminals. A touchscreen includes an array of touch switches on a display. A touch switch is the simplest kind of tactile sensor.

Video demonstrating the operation of a touch-sensitive lamp. A touch-sensitive lamp is a combination of a lamp and a touch switch. They act on the principle of body capacitance, activated by human touch rather than a flip, push-button, or other mechanical switch. They are popular as desk and nightstand lamps. Touch-sensitive lamp switches may ...
Darlington Transistor (NPN-type) In electronics, a Darlington configuration (commonly called as a Darlington pair) is a circuit consisting of two bipolar transistors with the emitter of one transistor connected to the base of the other, such that the current amplified by the first transistor is amplified further by the second one.

Together with the use of metallization, and the concepts of p–n junction isolation and surface passivation, it is possible to create circuits on a single silicon crystal slice (a wafer) from a monocrystalline silicon boule. The process involves the basic procedures of silicon dioxide (SiO 2) oxidation, SiO 2 etching and heat diffusion.
By creating a new kind of transistor using an ultrathin ferroelectric material made from boron nitride, the team used its unique electrical properties to create a super-fast, extremely tough, and ...
A programmable unijunction transistor (PUT) is a three-lead electronic semiconductor device which is similar in its characteristics to a unijunction transistor (UJT), except that its behavior can be controlled using external components. In a UJT, the base region is divided into two parts by the emitter.
Transistor–transistor logic (TTL) is a logic family built from bipolar junction transistors.Its name signifies that transistors perform both the logic function (the first "transistor") and the amplifying function (the second "transistor"), as opposed to earlier resistor–transistor logic (RTL) and diode–transistor logic (DTL).
