|
There's
many thing you need to know when finding the correct potentiometer, trimmer,
rheostat,
and dials such as:
|
-
What type of potentiometer do you have? Linear -
also
called linear taper, used for more industrial applications, more common of
styles. Audio -
also called audio taper, used for stereo & television controls
-
Shaft Length (Common
lengths are 2 inch round, 5/8 inch screwdriver slotted, and 7/8 inch
screwdriver slotted)
-
Standard or military bushing
-
Wattage (the most common being 2 watt)
-
Number of turns
(the
most common being 1 turn or 10 turn)
-
Ohms (wide variety)
