Disclosed is a potentiometer incorporating two sets of components in a molded case which provides a dual compact unit not easily damaged by flux and/or printed circuit board solvents. This design enables utilization of the less costly "open construction" versus the expensive "sealed construction" to build an instrument able to function under the operating conditions experienced in semiconductor manufacturing. Referring to Fig 1, the structure is a molded case 7 having terminal pins 1 molded into the base. A snap-fit cover 5 is used to securely close the opening into which the component parts are placed. This makes it possible to test the device prior to seal as well as salvage parts without difficulty. Wipers 4 attached to the rotor 3 contact the substrate 6.
