The particular features of this model are that it has no need of protection ring or protection cap or multiple units. The mounting is by clamps only. It has flexible output wires only (waterproof bass end with ceramic insulation not feasible) and the mechanical stop is not feasible.
Parameters for ordering a standard model, the Ohmic value should be between 500 ohms and 10,000 ohms and should have intermediary taps, electrical angle. It has a (close-to-) zero ohmic value may be done to use this model as a tap switch.
It has additional features such as special electrical or mechanical travel, and disconnection on specific angles. It has a special design of intermediary taps in the size and position – with ultra precision within one degree. It has a special shaft design and diameter, type, extended from front and/or from back of housing, flatted, slotted, pinned, etc. It has terminal wires such as special colors, cables, output wires positions, etc. Has special design for flanges for locating peg, special mounting mode, etc.
