push button

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

Depending on whether it is a normally open or normally closed contact, one of these pushbutton functions is triggered when pressed. When the button is pressed, a spring resistance is overcome and the contact is triggered. When released, the spring force returns the pushbutton 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 and the switch returns to its rest position. Pushbuttons are also available as tactile switches with tactile feedback.

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