TE Connectivity FSM4JRT 4-1437565-0, 5mm, 5mm, 160g, 1x NO, tactile switch *new*

A tactile switch is an on/off electronic switch that is only on when the button is pressed or if there is a definitive change in pressure. Another way to consider it, as momentary make or brake switch. As soon as a tactile switches button is released, the circuit is broken.

Tact switches are tactile electromechanical switches for keyboards, keypads, instruments or interface control-panel applications, which require user to get a feedback when the switch is pressed. User receives confirmation of successful switching in a form of a clicking sound and feeling. For these kind of situations tact switches are perfect choice.
