10mm 3 Pins carbon frequent adjustment potentiometer for motor
speed or volume control
Description
3pins Trimmer potentiometer can also be called semi-variable
potentiometer, it is mainly used to adjust the circuit that is not
often used.
The PT-10 potentiometers offer control where frequent adjustment is
required. The shaftless design allows for employment of different
engagement mechanisms, such as a customized shaft, a motorcontrol
or a human interface adjustment. This potentiometer can also
control variable outputs including frequency, change in motor speed
or volume
Features
1. Trimmer potentiomter is different from other potentimeters. It
is very small and easy to store. Which could store a few more in
case of having a problem with one of your home circuits.
2. The cost of this potentiometer is very low, but the role is very
important, so now most of the power switch will be used in the fine
tuning potentiometer (semi-variable potentiometer).

Application
Trimmer potentiometer quality is relatively good, life can be as
long as three or four years, but also can adjust the circuit of
various problems, it is also very much shape, can be applied to any
device. For example: robot animals, car switches, motor drivers,
radio control equipment, electric bicycles and so on.
