ABSTRACT:
A multiple operation type electrical part which is made very small in the axial direction as a result of using the space of a recess at the center portion of a first rotary member to prevent dislodgment of an inner shaft. Conventional multiple operation type electrical parts are large in the axial direction. They are large because dislodgment of the inner shaft is achieved by passing the inner shaft through five cases and an insulating plate, and by using the space in a case at the rearmost part of the electrical part. The multiple operation type electrical part of the invention makes it possible to overcome this problem present in conventional multiple operation type electrical parts.
