Abstract
The objective of the invention is to provide a compact and complex electronic component incorporating a rotary encoder capable of exact adjustment and a push switch with a long life-cycle. In order to achieve the objective, the push switch is fixed on a rear wall or a lower surface of the electronic component such that an essential of the push switch, i.e., a dome-shaped member, can be made larger and has longer fatigue life. Moreover, the rotary encoder includes a rotatable member and a resilient member. The rotatable member has a gear-shaped flange and is rotatable circumferentially relative to a central shaft of the rotary encoder. When the rotary encoder rotates, the resilient member, relative to the central shaft, is stationary. The resilient member has a V-shaped portion retained by a surface of the gear-shaped flange of the rotatable member such that the rotary encoder can be exact adjusted.
