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.

Abstract: An electrical switch includes a housing (1) with a cavity, a plurality of stationary contacts (2) embedded in the housing, a metal dome (3) received in the cavity, a handle (4) disposed onto the metal dome, and a cover (5) mounted onto the housing. The stationary contacts include a central stationary contact (231) and a plurality of peripheral stationary contacts (221), and the dome includes an arcuate central portion (31) covering the central stationary contact and a circular side portion (32) contacting with the peripheral stationary contacts. The handle defines a connecting portion (443), the connecting portion is apart from the dome during operation of the handle.

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.
