It has been a best-selling interlocking button for vending machines for a long time.
Developed and created 3 colors (Red Blue Green) LED lump-3in1.
It utilizes a “ renewalable from ” in which the outside case can be replaced. (Patent acquisition) By using a KOHA LED, it can display either “HOT” or “COLD” with a single button.
Indicating “HOT” and “COLD” with red and blue housings and LEDs.
Used in vending machines for cup-served beverages.
Achieving a low profile by separating the display units from the button.
The button also allows for a display of “please wait/in preparation” so that changes for sale are increased,. This uses a “Pure Green” KOHA LED.
A button is expanded by universal design correspondence.
