1K Multiturn Trimpot Trimming Potentiometer Through-hole 12V Relay and simple programming3296 3 8 Square Trimpot Trimming Potentiometers perform a variety of circuit adjustments in all types of electronic equipment. Lead screw, worm gear, and planetary gear are the three forms of actuation used in multi turn trimmers. Trimmers with lead screws have a linear wiper path, whereas those with worm gear and planetary gear have a circular path. Multiturn trimmers are ideal for Applications requiring precise resistance control. The potentiometer
