A sealed pushbutton switch ( 1 ) includes an insulative housing ( 2 ), a number of fixed contacts ( 7 ), an actuator ( 3 ) moveably retained in the insulative housing, a moveable contact ( 6 ) fastened to the actuator and including a pair of elastic beams ( 62 ) each provided with a contact portion ( 621 ) contactable to corresponding fixed contacts to establish a reliable electrical connection between the fixed contacts, and a spring ( 5 ) mounted below the actuator. When the actuator is pushed, the moveable contact has an agile movement to break the electrical connection between the moveable contact and the fixed contacts.
