Abstract:
An electronic component comprising:a base plate having a rear wall; a rotary encoder attached movably and rotatably on said base plate, said rotary encoder generating a switching signal when rotating; at least one push switch disposed on the rear wall; wherein said rotary encoder comprises: an operational member, the operational member being rotatably attached to said base plate; a rotatable member having a gear-shaped flange, the rotatable member following the operational member to rotate; a resilient member, the resilient member being stationary relative to the center of the operational member, the resilient member having a V-shaped portion retained by a surface of the gear-shaped flange such that said rotary encoder is precisely adjusted when said rotary encoder rotates; a first contact attached to a lower surface of the rotatable member; and a second contact being resilient and in touch with the first contact, the second contact sliding on said first contact to generate the switching signal when said rotary encoder rotates; wherein said rear wall includes an upper rear wall and a lower rear wall, and said at least one push switch includes a first push switch and a second push switch, wherein said first push switch is disposed on said upper rear wall, and wherein said second push switch is disposed on said lower rear wall; a first switching mechanism for selectively switching on said first push switch in response to the movement of said rotary encoder; and a second switching mechanism for selectively switching on said second push switch in response to the movement of said rotary encoder.
