Multi-functional control device with display buttons

A multi-functional control device with display buttons, comprising,

• a casing unit;
• a main circuit board disposed within said casing unit;
• and
• a plurality of press button modules disposed on said main circuit board and spaced apart from each other, each of said press button modules including
• a sub-circuit board electrically connected to said main circuit board, said sub-circuit board having a circuitry plate provided with a control circuit, and an electrical connector electrically connected to said circuitry plate,
• a micro-contact switch mounted on said sub-circuit board,
• an auxiliary case removably mounted on top of and in contact with said micro-contact switch,
• a driving circuit board removably disposed in said auxiliary case, and having a mating connector mating with said electrical connector of said sub-circuit board to establish an electrical connection with said main circuit board,
• a display module removably disposed on top of said auxiliary case, said display module including a micro light emitting diode array, and a flexible circuit board electrically bonded to said micro light emitting diode array and said driving circuit board, said flexible circuit board being configured to transmit a signal from said driving circuit board to said micro light emitting diode array for displaying an image, and
• a transparent cap covering said display module and said auxiliary case, and detachably connected to said auxiliary case,
• wherein, when said transparent cap is not pressed, said micro-contact switch opens said control circuit of said sub-circuit board, and
• wherein, when said transparent cap is pressed*, said transparent cap presses said auxiliary case, which in turn presses said micro-contact switch so that said micro-contact switch closes said control circuit of said sub-circuit board.
