A push-button switch with display screen includes a seat having an open-topped recess, a top cover located in the recess, a display screen, such as an LCD, an OLED or a TFT-LCD, located in below the top cover, an actuating member located in the recess below the display screen and connected to a microswitch located below the seat, a frame-like light-guiding member located in the recess around a periphery of the top cover, and a circuit board with light-emitting diodes located in the recess below the light-guiding member. The display screen is connected to an external circuit for displaying different dynamic or non-dynamic indicating images. When the light-emitting diodes are turned on to emit light onto the light-guiding member, a bright rim is generated along the periphery of the top cover to highlight the indicating images on the display screen and give the push-button switch a beautiful eye-catching appearance. |
