1. A push-button switch with display screen, comprising:

  • a seat having an open-topped recess of a predetermined depth defined therein, and a sleeve downward extended from a center of the recess by a predetermined length;

    an actuating member being located in the recess of the seat and having a hollow post downward extended from at a center thereof;

    an top cover being located in the recess of the seat above the actuating member;

    a display screen being located in below the top cover and above the actuating member to connect with a first circuit board, and the first circuit board being connected to an external circuit via a cable;

    a light-guiding member being located in the recess of the seat around a periphery of the top cover;

    a second circuit board being provided on a top with a plurality of light-emitting diodes spaced along a periphery of the second circuit board corresponding to the light-guiding member and the seat for emitting light to irradiate on the light-guiding member and the seat; and

    a microswitch being fixedly mounted on a mounting base below the seat, an upper end of the microswitch being connected to the post of the actuating member, such that the microswitch is on when the top cover is downward pushed;

    whereby when the display screen is driven by the externally connected circuit, different dynamic or non-dynamic indicating images are displayed on the display screen; and

    when the light-emitting diodes on the second circuit board are turned on to emit light, the emitted light is irradiated on and guided by the light-guiding member to generate a bright rim along the periphery of the top cover to thereby enable an enhanced display effect of the display screen and a beautiful eye-catching appearance of the whole push-button switch.
