Abstract

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.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 143 words
A multiple operation type electrical part comprising: a rotatable cylindrical outer shaft; a rotatable inner shaft inserted in the outer shaft, the inner shaft being movable in an axial direction thereof; a first rotary electrical part comprising a first rotary member actuated by the rotational motion of the outer shaft, the first rotary member having a center portion; a second rotary electrical part comprising a second rotary member actuated by the rotational motion of the inner shaft; a push switch operated by the axial movement of the inner shaft; a dislodgment preventing member mounted to the inner shaft; and wherein the center portion of the first rotary member has a recess for inserting the inner shaft therein; and wherein contact between an inner wall of the recess and the dislodgment preventing member prevents dislodgment of the inner shaft in a front axial direction.
Claim 2
Dependent Claim 143 words
A multiple operation type electrical part comprising: a rotatable cylindrical outer shaft; a rotatable inner shaft inserted in the outer shaft, the inner shaft being movable in an axial direction thereof; a first rotary electrical part comprising a first rotary member actuated by the rotational motion of the outer shaft, the first rotary member having a center portion; a second rotary electrical part comprising a second rotary member actuated by the rotational motion of the inner shaft; a push switch operated by the axial movement of the inner shaft; a dislodgment preventing member mounted to the inner shaft; and wherein the center portion of the first rotary member has a recess for inserting the inner shaft therein; and wherein contact between an inner wall of the recess and the dislodgment preventing member prevents dislodgment of the inner shaft in a front axial direction.
Claim 3
Dependent Claim 36 words
A multiple operation type electrical part according to claim 1, wherein the first rotary member is coupled to the outer shaft laterally away from an inner wall portion that makes contact with the dislodgment preventing member.
Claim 4
Dependent Claim 44 words
A multiple operation type electrical part according to claim 2, wherein the first rotary member has a stepped bottom wall formed at an insertion hole connected to the recess and extending in an axial direction thereof, bottom wall being coupled to the outer shaft.
Claim 5
Dependent Claim 36 words
A multiple operation type electrical part according to claim 3, wherein the first rotary member comprises a movable contact and a linking member positioned within the recess, the linking member being coupled to the outer shaft.
Claim 6
Dependent Claim 56 words
A multiple operation type electrical part according to claim 4, further comprising a self-returning coil spring provided at an outer periphery of the linking member, the coil spring having an arm which is moved by the first rotary member in order to cause the outer shaft to return to an original position by the coil spring.
