Electrically insulated from each other are a pair of contact rings (52,58) held respectively against the clamping nut (48) on the body and a second final nut contacting the stem, the rings having take-off leads. A molded rubber shroud (64) protects the rings and holds them and an insulating spacer (56) in proper relation.</p> |
