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.
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 button is pressed and makes contact when it is released. An example of a push-to-break switch is a button used to release a door held closed by an electromagnet.

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.
Power On (IEC 60417-5007) and Power Off (IEC 60417-5008) symbols are used to indicate positions of the rocker switch Power button marked with Standby symbol (IEC 60417-5009) turns the device on or off without fully disconnecting power supply. A power symbol is a symbol indicating that a control activates or deactivates a particular device.
A DIAC stands for DIode AC Switch. A gate turn-off thyristor (GTO) is a bipolar switching device. Electronic switches may also consist of complex configurations that are assisted by physical contact, for instance resistive or capacitive sensing touchscreens. Network switches reconfigure connections between different ports of computers in a ...
