While there are alternative input technologies such as silicon topple domes, pushbutton switches, capacitive touch sensors and touch panels, the tact switch stands out as a popular human interface solution due to its great versatility. The tact switch gives a clear indication to the user that it has been successfully actuated. Their small size helps maximize board space and the molded body and metal contact provide long life. Panasonic offers optional reel packaging which allows for high speed mounting and with the tact switches wide availability you can be ensured continued support through long product cycles.
