Terminals

Precision potentiometers have three types of standard soldering terminals as shown in Figure 11.2:
  • Lug type terminals
  • Turret type terminals
  • Printed circuit board terminals
Figure 11.2
Typically, there are three terminals on each precision potentiometer. Two are attached to the ends of the resistive element and one is attached to the collector ring, which translates the position of the wiper along the resistive element. The collector ring is at the back of the housing as shown in Figure 11.3.
