ABSTRACT:
A rotary housing is provided including relatively electrically insulated and electrically conductive inner and outer peripheral portions with which electrical contacts are electrically engaged. The housing is hollow and encloses a quantity of electrically conductive liquid which, when the housing is rotating below a predetermined low speed of rotation or is stationarily positioned with at least a first predetermined peripheral portion lowermost, establishes electrical contact between the inner and outer peripheral portions and which, when the housing is rotating above the aforementioned predetermined low speed of rotation or is stationary with a second predetermined peripheral portion lowermost, is ineffective to establish electrical contact between the inner and outer peripheral portions.
