Abstract
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.
