Abstract: The invention includes a switch and sealing arrangement that provides positive sealing and is easy to assemble. The invention includes a switch housing having an upper compartment that is in communication with an exterior of the switch housing and has drainage slots therein. The upper compartment is separated from a lower compartment by an inner base in which a cylindrical barrel extends upwardly from the inner base. The lower compartment of the switch housing receives an electrical contact switch therein that is controlled by an actuator lever that is in contact with a post extending through the cylindrical barrel from a rocker button. A seal is provided that has an outer lip and an inner opening and is mounted on the upwardly extending cylindrical barrel such that the outer lip engages an outer surface of the cylindrical barrel. The post of the rocker button fits into the inner opening of the seal and seals the lower compartment from upper compartment when the rocker button is engaged to the switch housing. The rocker button is constructed to be removeably snap fit to the switch housing. The seal is constructed to allow the post of the rocker button to pivot without causing stress on the periphery of the seal.

Abstract translation: 本发明包括提供正密封并易于组装的开关和密封装置。 本发明包括开关壳体，其具有与开关壳体的外部连通并且在其中具有排水槽的上隔室。 上隔室通过内底座与下隔室分离，其中圆柱形筒从内基座向上延伸。 开关壳体的下隔室在其中容纳电接触开关，该电接触开关由致动器杆控制，该致动器杠杆与从摇臂按钮延伸穿过圆柱形筒的柱接触。 提供具有外唇缘和内开口并且安装在向上延伸的圆柱形筒上的密封件，使得外唇缘接合圆柱形筒的外表面。 当摇臂按钮接合到开关壳体时，摇杆的按钮适合于密封件的内部开口，并将下隔室与上隔室密封。 摇杆按钮被构造成可拆卸地卡扣配合到开关壳体。 密封件被构造成允许摇杆按钮的柱枢转而不会在密封件的周边上产生应力。
