The production process and key steps of waterproof tactile switch

Material selection:
The switch body is usually made of high temperature resistant and corrosion-resistant materials, such as stainless steel, aluminum alloy, or engineering plastics.
The internal circuit board needs to be made of waterproof materials such as epoxy resin or silicone to prevent moisture from entering and causing damage.
Design and processing:
Firstly, design the circuit board and casing according to the functional and dimensional requirements of the switch.
Manufacturing circuit boards requires the use of precision printed circuit board (PCB) processing technology to ensure reliable circuit connections.
The processing of the shell usually adopts CNC machining or injection molding to ensure dimensional accuracy and appearance quality.

Assembly process:
Assemble components such as circuit boards and switch buttons into the interior of the casing according to design requirements.
During the assembly process, special attention should be paid to the installation of seals to ensure waterproof performance.
At the same time, inspect and debug each connecting part to ensure that the switch functions properly.
Waterproof treatment:
After assembly, waterproofing the switch is a crucial step.
The circuit board and key components can be wrapped in waterproof materials using methods such as dip coating, spray coating, or potting.
At the same time, seal the connection lines and interfaces of the switch to prevent moisture from seeping in.
Performance testing:
The completed waterproof tactile switch needs to undergo strict performance testing.
Including static water pressure testing, wet heat cycle testing, corrosion resistance testing, etc.
Only switches that have passed testing and meet relevant standard requirements can be put into use.
Quality Control:
Strictly controlling the quality of each link in the production process is the key to ensuring stable switch performance.
Conduct comprehensive testing and quality control of raw materials, processing techniques, and finished products to ensure reliable product quality.
Through the above processes and steps, the waterproof touch switch produced not only has good waterproof performance, but also ensures stability and reliability, making it suitable for various outdoor and humid environments.
