ABSTRACT:
An electrical switch functioning as a tilt, proximity or relay switch includes an elongate cylindrical housing with a first open end and a second closed end. A flexible spring extends longitudinally in the housing and is supported away from the housing by a seal at the open end. The housing and spring are electrically conductive and an electrically-conductive spherical ball is located within the housing for selective rolling engagement with the spring and housing. The switch functions as a single pole single throw type switch. A second spring can be located at the closed second end of the housing and supported similar to the first spring. By locating the spherical ball between the two springs, a single pole double throw switch is formed.
