Abstract
An adjustable magnet carrier 100 for a rotary valve indicator apparatus 10 is disclosed. The adjustable magnet carrier 100 includes an extension member 117 having an extension member body 118, an extension member body top 119, and an extension body base 121. Upper and lower magnet carriers 144, 146 selectively rotate about extension member 117 to adjust the stand-off between the magnets 102, 104 and the magnetically responsive switches 30, 32. The magnetically responsive switches are hermetically sealed within a separate electronics switch housing 15. Light-emitting diodes 42, 44 radiate from electronics switch housing 15 in response to switches 30, 32. Drive shafts 124, 128 rotate the magnet carriers 144, 146. The outer surfaces of the upper and lower magnet carriers 144, 146, the ends of drive shafts 124, 128, and the light-emitting diodes 42, 44 are color-coded to correspond to each other and to the open and closed positions of rotary valve element 19.
