Variable Resistor (271-1732B) Hints and Tips Faxback Doc. # 14519 This product is identical to the Variable Resistor (271-1732) with the exception of the Detents. The Detents on the 271-1732B are different from the original (271-1732). There are only three legs on the pinout and since it is a variable pot, the three legs are standard. (IR/all-04/05/95)
