push button

A push button

differs from a switch in that the contact is only activated as long as the push button is pressed. Afterwards, it returns to its initial position.

Depending on whether it is a make or break contact, one of these button functions is triggered when pressed. When the button is pressed, a spring resistance is overcome and the contact is triggered. When the button is released, the spring force returns the button to its initial position. In addition to the classic pushbutton principle mentioned above, there are also the interlocking switches. These switches remain in the locked position until the button is pressed again to return them to the rest position. Pushbuttons are also available as tactileswitches

with tactile feedback. Typical examples of pushbuttons are the keys of a keyboard, an electronic keyboard or the mouse buttons.
