Abstract
A tact switch ( ) includes a top cover ( ), an actuator ( ), a metal dome ( ), a rubber disc ( ), a conductive disc ( ) and a housing ( ). The housing has four contacts ( ) retained therein. The rubber disc is attached to an underside of the metal dome, and the conductive disc is attached to the rubber disc. The metal dome fits into a bottom of the housing with the conductive disc spaced a short distance above the contacts. The actuator is slidably mounted above the metal dome. The top cover is mounted on the housing and includes a plate ( ) with a curved lever ( ) extending therefrom. The curved lever confronts a ramp ( ) of the actuator. In operation, when the actuator is pressed into the housing, the lever of the top cover is forced downwardly by the ramp of the actuator to depress the metal dome, which pushes the conductive disc into electrical connection with the contacts.
