Rotary switch for multiple circuits

摘要

A multi-position rotary switch for switching among three power sources or batteries to maintain at least one of the power sources or batteries in service while switching among positions providing separate service from each of the three power sources or batteries and service of two power sources in series while the other power sources is in service which includes a stator of suitable insulating material having a series of discrete electrical conductor segments in two concentric circular paths with the positive terminal of each of the three power sources connected to a discrete segment and with the negative terminals of two of the three power sources connected to a discrete segment and the negative terminal of the other of the three power sources connected to a discrete segment; the discrete segments are arranged in a pattern such that the switch rotor having three radial shorting conductor bars for intermittently coupling discrete segments between the two circular paths upon sequential rotation from off through four positions to off again will provide separate outputs from each of the three power sources and separate output from one power source along with series output across the other two power sources.
