Potentiometer with detent switch

PWS is a detent switch potentiometer. There is a centere detent switch potentiometer.

  • Potentiometer with detent (PWS-25) is a conductive plastic potentiometer with center on off switch.
  • PWS-25 is available in two standard ohmic values 5k ohms and 10k ohms with a center tac-tile switch makes it a compact solution for several applications.
  • PWS-25 is a conductive plastic potentiometer and hence has a extremely long life.
  • PWS-25 is available with a single turn or endless without stop version.
  • Technical
  • Mechanical
  • Electrical


  • Medical Equipment.
  • Stereo System.
  • Variable microcontroller based power supplies.
  • Casino panel


For best performance of PWS-25 below points needs to be taken into consideration.
1) The hole in the panel should not be more than 9.5mm.
2) PWS-25 should be mounted with Star washer given along with the product and perpendicularity between the panel and axis of Sensor should be maintained.
