  2. Push-button - Wikipedia

    en.wikipedia.org/wiki/Push-button

    A push-button (also spelled pushbutton) or simply button is a simple switch mechanism to control some aspect of a machine or a process. Buttons are typically made out of hard material, usually plastic or metal. [1] The surface is usually flat or shaped to accommodate the human finger or hand, so as to be easily depressed or pushed.

  3. Switch - Wikipedia

    en.wikipedia.org/wiki/Switch

    The most common type is a "push-to-make" (or normally-open or NO) switch, which makes contact when the button is pressed and breaks when the button is released. Each key of a computer keyboard, for example, is a normally-open "push-to-make" switch. A "push-to-break" (or normally-closed or NC) switch, on the other hand, breaks contact when the ...

  4. IEEE 1905 - Wikipedia

    en.wikipedia.org/wiki/IEEE_1905

    The push button method requires the user to press one button on a new (i.e. not in-network) 1905.1 device and one button on any 1905.1 device already in the network. It is not necessary for the user to know which technology is used by the new device to join the network, and which device will process the pairing and admission of this new device ...

  5. Light switch - Wikipedia

    en.wikipedia.org/wiki/Light_switch

    In the U.S., the buttons were commonly black; the "on" button typically had a white mother-of-pearl (real or simulated) inlay to indicate its function. By convention, the switch was customarily installed with the "on" button on top. Push-button switch reproductions are available on the market today for vintage or authentic styling.

  6. Push switch - Wikipedia

    en.wikipedia.org/wiki/Push_switch

    A push switch (button) is a momentary or non-latching switch which causes a temporary change in the state of an electrical circuit only while the switch is physically actuated. An automatic mechanism (i.e. a spring ) returns the switch to its default position immediately afterwards, restoring the initial circuit condition.

  8. Electrical contact - Wikipedia

    en.wikipedia.org/wiki/Electrical_contact

    When the contacts touch, the switch is closed; when the contacts are separated, the switch is open. The gap must be an insulating medium, such as air, vacuum, oil, SF 6. Contacts may be operated by humans in push-buttons and switches, by mechanical pressure in sensors or machine cams, and electromechanically in relays.

  9. Touch switch - Wikipedia

    en.wikipedia.org/wiki/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 be dimmable, allowing the brightness of the lamp to be adjusted by multiple touches. Most stop at level 3, which is for the ...
