Features of 4x4 Translucent Silicone Button Keypad
A round ring conductive ink is printed on the back side of each button, contacting the exposed PCB traces to complete the circuit.
A single small hole in the bottom of the button accepts a 3mm or 5mm diameter tri-color LED to create the button interface of your choice.
Proper key travel design provides positive tactile feedback.
Screen printing on key tops for multiple appearance and aesthetic options and spray polyurethane for added durability.
Our 4x4 transparent silicone button keypads have very high design flexibility and can be split into different specifications of button keypads, namely 2x2, and 2x4.

Production Process of 4x4 Translucent Silicone Button Keypad
Step One: Use the right materials
To use suitable specifications of silicone rubber materials, conductive ink, and vulcanizing agents. The right hardness is key to soft silicone keys.
Step 2: Molding
After preparing the correct specifications of the silicone rubber material, use a specific mold and compression molding process to start production. Temperature, pressure, and vulcanization time are crucial to the quality of the silicone buttons keypad.
Step 3: Secondary vulcanization (Optional)
After high-temperature vulcanization, the product undergoes secondary vulcanization to remove residues and improve performance. The product is usually placed in a vertical oven and baked at 180-200°C for 2-4 hours.
Step 4: Surface treatment (Optional)
To meet the performance or appearance requirements of some customers for the surface of silicone buttons, different processes or methods are usually used to process the product's surface, such as silk screen printing, spray laser engraving, PU coating, matte smooth coating, etc.
Step 5: Trimming
To make the silicone buttons perfect, the excess burrs of the silicone buttons are usually trimmed manually. This is sometimes done using a punch press.
Step 6: Final inspection, packaging
All products will eventually undergo random inspection by our quality department. Unqualified products will be scrapped directly. Qualified products will enter our finished product warehouse before packaging.
