Abstract: A method of mounting a potentiometer (pot) on a plate, wherein a hollow cylindrical housing appendage of the pot is positioned through a hole in the plate to the other side thereof. The rotatable shaft of the pot then projects to the said other plate side through the appendage. A washer, a jam nut and a seal nut are positioned around the appendage. A compound is then potted in contact with and around the pot housing sealing it to the plate, and around the shaft. The housing on its side of the plate is larger than the hole. However, the shaft is not primed and is therefore rotatable after potting. The plate is primed on both sides prior to potting.
