Abstract: A position responsive switch having a ball received within a hollow cylindrical conductor. Depended upon the position of the switch, the ball may contact only the hollow cylindrical conductor or it may also contact a second conductor to complete a circuit between the two conductors. The cylindrical conductor and ball are enclosed in a two-part insulating housing, including a hollow member having one closed end, and a cap for closing the open end of the hollow member. Electrical leads are connected to the two conductors through the closed end of the hollow housing member.

Abstract: A method is disclosed for manufacturing insulated grounding straps of the type used for grounding a television chassis. The straps are produced from a continuous length of insulated flat strip conductor. Holes are punched on either side of a severing point selected according to the desired length of the strap. The continuous length is then severed between the holes and the insulation removed near the ends of the severed lengths.
