Type 23 Series
A popular range of 20mm control
potentiometers, the type 23 series
can be tailored to suit more specific
requirements. The potentiometers
are available with printed carbon
resistance element, choice of bush
lengths in metal or plastic and
insulated shafts up to 50mm in
length. In addition, approved mains
and low current switches are
available as standard options.
