Abstract:
1. A rotary switch comprising: an electrode matrix comprising multiple switches arranged in spaced radial positions along an arc, each switch having paired first and second electrodes, with one of the first and second electrodes having a non-conductive portion; a contact operably coupled to the electrode matrix for movement along the arc to close and open the switches by electrically coupling and uncoupling the first and second electrodes for each switch as the contact is moved through the arc; and a detent mechanism operably coupled to the contact and having a detent position for the contact of each of the switches such that the contact is in the detent position when the contact overlies the non-conductive portion; wherein when the contact is moved through the arc it momentarily couples the first and second electrodes of each switch when not in the corresponding detent position and uncouples the first and second electrodes when in the detent position.
