Custom Potentiometers reduce the problem of the crowding of higher current settings toward one end of a potentiometer. Custom potentiometers are much more difficult to manufacture than standard, linear potentiometers. These custom potentiometers are only partially effective in addressing the issue of uneven marking and crowding of settings.

Customized Switches are built in to the unit to operate such accessories as brake & backup lights, radio-speaker controls and manual siren brake. Customized switches are developed for industry specific applications.
