Multiple operation type electrical part

A multiple operation type electrical part, comprising:

• a rotatable cylindrical outer shaft;
• a rotatable inner shaft inserted in the outer shaft and movable in an axial direction;
• a first rotary electrical part comprising a first rotary member and an insulating base member, said first rotary member being actuated by the rotational motion of the outer shaft and including a slide contact mounted on a surface of the first rotary member, and said insulating base including a sliding member mounted to a first surface of the insulating base member so as to protrude therefrom and slidably engage the slide contact of the first rotary member;
• a clicking member which is mounted to a second surface of the insulating base member;
• a second rotary electrical part comprising a second rotary member and an insulating case, the second rotary member being actuated by the rotational motion of the inner shaft and including a bumpy portion and a contact portion, the bumpy portion engaging the clicking member, the contact portion being disposed on a surface of the second rotary member opposite to the bumpy portion, and the insulating case having a contact member which slidably engages the contact portion of the second rotary member;
• and
• a push switch having a switch contact disposed on the insulating case, an actuating member which moves integrally with the axial movement of the inner shaft, and a movable contact which is moved by the actuating member so as to connect said movable contact with the switch contact and activate said push switch,
• wherein the clicking member comprises a mounting portion and an clicking protrusion, said mounting portion formed of a metallic plate and being mounted to the second surface of the insulating base member, and said clicking protrusion being formed to engage the bumpy portion of the second rotary member so as to provide a tactile feel as a result of the rotation of the inner shaft,
• wherein the insulating base member comprises a pair of sliding members disposed on opposite sides of the insulating base member,
• and wherein the mounting portion of the clicking member is mounted to the second surface of the insulating base member at a plurality of locations, each of said locations being disposed between said pair of sliding members.
