ABSTRACT:
A housing assembly for a magnetically controlled element used to detect the angular position of a rotatable shaft includes at least one cavity for holding a corresponding number of insertable switch capsules, which capsules are preferably removable. The capsules are readily fitted in the cavities to precisely position a magnetic reed switch encapsulated therein into close proximity to a rotating shaft having a magnetic insert on at least one circumferential sector. The capsules also optionally include reed switch activated SCR circuits for generating an AC power output signal dependent upon the angular position of the rotatable shaft.
