Abstract
A sealed pushbutton switch (1) includes an insulative housing (2) defining a cavity (25), an actuator (3) movably retained in the insulative housing, a base (8) conglutinated to the insulative housing by glue, a number of fixed contacts (7) assembled to the base, a spring (5) mounted below the actuator, and a movable contact (6) mounted on the actuator and provided with a number of contact portions (621) in contact with corresponding fixed contacts. The movable contact is movable with the actuator from a first position to a second position relative to the insulative housing along a top-to-bottom direction to disengage the fixed contacts. The base has four slots (811) defined near four sides thereof.
