Combining Piher’s PT-15V or PS-15 control potentiometers with a separate detent control mechanism (DCM) enables a cost effective solution for appliance controls. The potentiometer can be soldered to the control board and in a separate step the DCM can be assembled over it. The detent torque can be modified according to customer requirements (e.g. depending on the input dial’s diameter) as can the number and position of the detents. This removes the need to build detents into the user front panel of the appliance, simplifying, and significantly reducing the total cost of the solution. For additional time and operation cost savings the assembly of potentiometer, detent mechanism and shaft can be delivered pre-assembled.
