Description

  The present invention relates to a push switch unit that turns on a push switch by pushing down a push button, and a rotary encoder unit that is configured to operate a rotary electronic component such as a pulse switch or a variable resistor by rotating the rotary knob. Relates to a rotary electronic component with a push switch.

  Push switch rotary encoder with push switch configured as a composite type switch by integrating the push switch part that turns on the push switch by pushing down the push button and the rotary encoder part that operates the pulse switch by rotating the rotary knob. The switch is known conventionally (for example, refer patent document 1).

  The push switch of the rotary encoder switch with push switch has a push switch mechanism that turns on push switch parts such as a tact switch by depressing the push button, and the rotary encoder section has a rotary knob. Thus, a rotary encoder switch mechanism that outputs a rotation angle and a rotation direction is provided.

  When operating the conventional rotary encoder switch with push switch as a push switch, when the push button is pushed down, the push switch contact plate is pushed in and reversed at the tip of the shaft part formed integrally with the push button, and this reversal operation is performed. Thus, two spaced apart electrodes were brought into contact with each other to be in the on state. On the other hand, when the push button is released, the push button is pushed up by the restoring force of the inverted push switch contact plate, and the two electrodes are separated and turned off.

In addition, in a conventionally known rotary encoder switch with a push switch, a compression coil spring is interposed on the back side of the push button, and when the push button is released, the return of the compression coil spring is restored. Some are configured to be done by force.
