Custom Silicone Rubber Keypads 60 Shore A Waterproof Membrane Switch Buttons for Industrial Control Panels

Custom Silicone Rubber Keypads 60 Shore A Waterproof Membrane Switch Buttons

Our silicone rubber keypads are compression molded from 100% virgin silicone rubber in 60 Shore A, matched to your 2D/3D drawings or a physical sample. Each key is built around a carbon pill, conductive ink or metal dome contact, sealed with a molded perimeter lip so the assembly keeps its switching function in humid, dusty and wash-down environments. Surface treatments include PU coating, matte finish, epoxy resin dripping, spray feel oil and laser etched or screen printed legends.

Application Scenarios

Because the keypad combines tactile feedback, sealing and a printed graphic overlay in one part, it fits equipment that is operated by hand in demanding environments:

• Industrial control panels and machine HMI: sealed keypads resist coolant mist, metal dust and repeated cleaning on CNC, packaging and textile machinery.
• Medical and laboratory instruments: non-toxic, odorless silicone with wipe-down surfaces suited to patient monitors, analyzers and sterilizable housings.
• Automotive, marine and off-highway dashboards: stable from -40°C to 220°C with UV and oil resistant options for control heads and instrument clusters.
• POS terminals, vending and ticketing machines: high cycle life for public-use keypads that are pressed thousands of times per day.
• Smart home, intercom and remote controls: backlit legends with light guide pads keep keys readable in dark rooms.
• Test, measurement and security equipment: metal dome versions deliver a crisp click feel with low contact resistance for precision instruments.

Key Parameter Table

Quality Assurance

• Incoming material control: silicone compound is batch tested for hardness, tensile strength, tear strength and viscosity before molding.
• First article approval: a golden sample and dimensional report are signed off against your drawing before mass production starts.
• In-process inspection: press parameters, key height, webbing thickness and legend position are checked every production shift.
• 100% functional test: every keypad is pressed and resistance checked, with a 10 million cycle life test on the sampled lot.
• Environmental reliability: high and low temperature cycling, humidity aging, salt spray and oil resistance tests are available on request.
• Certification: ISO 9001 quality system, RoHS and SGS reports supplied with each shipment.

Packaging Standards

• Each keypad is separated by a PE bag or anti-static bag to prevent surface scuffing and dust adhesion.
• Parts are stacked in molded trays or dividers so keys keep their shape during transit; no direct weight on key caps.
• Inner box with product label showing drawing number, hardness, batch number and quantity.
• Export grade five-layer corrugated carton with moisture barrier liner and strapping.
• Custom retail packaging, barcode labels and pallet configuration available on request.
• Carton dimension and gross weight are confirmed with the customer before shipment.

After-sales Service

• Response time: technical questions answered within 12 working hours; formal 8D report issued within 3 working days for any quality claim.
• Warranty: 12 months from shipment against defects in material and workmanship under correct use.
• Free replacement: parts confirmed as our manufacturing defect are remade and shipped at our cost.
• Tooling care: molds are stored free of charge for 3 years, with free maintenance and drawing revision support.
• Engineering support: free 3D drawing and structure suggestion before order, plus sample rework support after delivery.

FAQ

Q: What is your minimum order quantity for a custom keypad?
A: 3,000 pieces per drawing for a new mold, and 1,000 pieces for repeat orders of an existing mold.

Q: How long does tooling and sampling take?
A: Mold making and first sample take about 10 working days after drawing confirmation; mass production takes 15 to 20 working days after sample approval.

Q: Can you produce from our 2D/3D file or a physical sample?
A: Yes. We work from IGES, STEP, DWG, PDF drawings or a physical sample, and return a 3D model for your confirmation before cutting steel.

Q: How do you keep the keypad waterproof?
A: A molded perimeter sealing lip, controlled webbing thickness and optional double-sided adhesive frame give IP54 to IP67 protection depending on the housing design.

Q: Can the legends and backlight be customized?
A: Yes. Laser etching, screen printing, embossed key tops and light guide pads with LED windows are all available.

Q: What are your payment terms?
A: 50% deposit by T/T with the balance against the copy of the bill of lading, and L/C or Western Union for other cases.
