Abstract: A waterproof electrical socket connector includes a connector housing and a plurality of contact members. The connector housing includes a first housing portion and a second housing portion coupled to and configured to cover the first housing portion. The first and second housing portions define a cavity and an opening configured to permit extension of a plug into the cavity. Each of the contact members includes a terminal portion disposed outwardly of the connector housing, a contact portion for establishing electrical contact with the plug, and an embedding portion that interconnects the terminal portion and the contact portion and that is embedded in the first housing portion by insert molding.

Abstract: A tilt switch comprises an insulating housing, a cover covering the opening of the housing, three terminals fixed at the bottom of the housing and an electrically conductive ball movably received in the housing to on/off the switch by contacting/leaving said terminals. Three terminals are located at each vertex position of a triangle such that one terminal having a polarity opposite to the other two terminals and a protruding length longer than those of the other two terminals, allowing elevation difference to exist between them.
