ABSTRACT:
A rotatively-operated electronic component with a push switch includes a rotatable operation knob. A rotary contact plate is connected to the operation knob for motion together with the operation knob. Resilient contact arms provided on an attachment base plate touch the rotary contact plate. The resilient contact arms and the contact plate cooperate to generate an electric signal in response to rotation of the operation knob. A drive member connected to the attachment base plate rotatably supports the rotary contact plate. The drive member is swingable relative to the attachment base plate. The drive member is allowed to swing relative to the attachment base plate by application of a force to the operation knob. A push switch portion is supported on the attachment base plate. The push switch portion is actuated in response to swing of the drive member relative to the attachment base plate by the application of the force to the operation knob.
