Abstract
A spring loaded contact device having a housing with an internal bore, a spring disposed in the bore, a pin disposed in and extending from the bore, and a dimple formed in the housing that secures the pin in the bore. A first portion of the pin contacts the spring, a center portion of the pin is smaller than the first portion and protrudes from the bore, and a head of the pin is disposed external to the bore and has a rounded cylindrical end. A rotary connector using the spring loaded contact devices has first and second printed wiring boards that rotate relative to each other that are electrically interconnected using a plurality of spring loaded contact devices disposed on the first printed wiring board. The spring-loaded contact devices are used to transfer electrical signals or power to conductive contacts formed on the second printed wiring board.
