Rotatively-operated electronic component with push switch and rotary encoder

A method of manufacturing a rotatively-operated component with a push switch, comprising the steps of:

• previously combining parts of a push switch portion and a fixed base plate of a rotary component portion into a switch block;
• using an inverted U-shaped binding member as a reference while sequentially stacking a bushing, an operation shaft, a rotatable member, and the switch block from below with respect to the inverted U-shaped binding member;
• and
• bending edges of legs of the inverted U-shaped binding member into engagement with a lower surface of the switch block to combine the bushing, the operation shaft, the rotatable member, and the switch block together.

A composite device comprising:

• a common shaft being rotatable circumferentially and being movable axially;
• a rotatively-operated component including a rotary member having a contact thereon and being operated in response to rotation of the rotary member which engages said contact with a fixed contact;
• a key coupling for connecting the rotary member in the rotatively-operated component with the common shaft, and allowing the rotary member to rotate in response to rotation of the common shaft and to be stationary independent of axial movement of the common shaft;
• a push switch including an axially movable member and being operated in response to axial movement of the axially movable member, and
• means for connecting the axially movable member with the common shaft and allowing the axially movable member to move axially in response to axial movement of the common shaft;
• wherein the key coupling includes an axially-extending pin provided on one of the common shaft and the rotary member in the rotatively-operated component, the axially-extending pin fitting into a recess in the other of the common shaft and the rotary member, the axially-extending pin being at a position separate from a center of rotation of the common shaft.
