2. Touch switch - Wikipedia

   en.wikipedia.org/wiki/Touch_switch

   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.

3. Capacitive sensing - Wikipedia

   en.wikipedia.org/wiki/Capacitive_sensing

   Capacitive sensors are constructed from many different media, such as copper, indium tin oxide (ITO) and printed ink. Copper capacitive sensors can be implemented on standard FR4 PCBs as well as on flexible material. ITO allows the capacitive sensor to be up to 90% transparent (for one layer solutions, such as touch phone screens).

4. Touch-sensitive lamp - Wikipedia

   en.wikipedia.org/wiki/Touch-sensitive_lamp

   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 ...

5. Dimmer - Wikipedia

   en.wikipedia.org/wiki/Dimmer

   When the dimmer is at 50% power, the switches are switching their highest voltage (>325 V in Europe) and the sudden surge of power causes the coils on the inductor to move, creating a buzzing sound associated with some types of dimmer; this same effect can be heard in the filaments of the incandescent lamps as "singing". The suppression ...

6. Touchscreen - Wikipedia

   en.wikipedia.org/wiki/Touchscreen

   Back side of a Multitouch Globe, based on projected capacitive touch (PCT) technology Schema of projected-capacitive touchscreen. Projected capacitive touch (PCT; also PCAP) technology is a variant of capacitive touch technology but where sensitivity to touch, accuracy, resolution and speed of touch have been greatly improved by the use of a ...

7. Multi-touch - Wikipedia

   en.wikipedia.org/wiki/Multi-touch

   Multi-touch is commonly implemented using capacitive sensing technology in mobile devices and smart devices. A capacitive touchscreen typically consists of a capacitive touch sensor, application-specific integrated circuit (ASIC) controller and digital signal processor (DSP) fabricated from CMOS (complementary metal–oxide–semiconductor ...

8. Applications of capacitors - Wikipedia

   en.wikipedia.org/wiki/Applications_of_capacitors

   The force of the rotational field is not constant, but is sufficient to start the rotor spinning. When the rotor comes close to operating speed, a centrifugal switch (or current-sensitive relay in series with the main winding) disconnects the capacitor. The start capacitor is typically mounted to the side of the motor housing.

9. One Glass Solution - Wikipedia

   en.wikipedia.org/wiki/One_Glass_Solution

   One Glass Solution [1] (OGS) is a touchscreen technology which reduces the thickness of a display by removing one of the layers of glass from the traditional capacitive touchscreen stack. The basic idea is to replace the touch module glass with a thin layer of insulating material. In general, there are two ways to achieve this.
