Conductive Rubber Keypads 50 Shore A Carbon Pill OEM Remote Control Button Pad

Conductive Rubber Keypads 50 Shore A Carbon Pill OEM Remote Control Button Pad

Product Introduction

These conductive rubber keypads combine a 50 Shore A silicone rubber body with moulded carbon pills, giving a tactile response and a stable electrical contact on every keystroke. Each keypad is compression moulded to your 2D drawing or 3D file, so button layout, travel, actuation force and legend printing are built around your enclosure instead of adapted from a catalogue part. Carbon pills are post-cured and contact resistance tested before assembly, which keeps the keypad responsive on low-voltage control boards used in remote controls, industrial panels and medical devices.

Application Scenarios

• Remote controls and handheld terminals - TV, air conditioner, gate and industrial RF remotes where repeated key presses and carbon pill contact stability matter.
• Industrial control panels - machine HMI overlays, meter keypads and instrument front panels that need oil, dust and solvent resistance.
• Medical and laboratory equipment - analysers, patient monitors and pump interfaces where a smooth, wipe-clean silicone surface is required.
• Automotive and motorcycle electronics - dashboard switches, seat and window control pads that operate from -40 °C to +200 °C.
• Household appliances and security devices - washing machine panels, intercom and access control keypads with backlit legends.
• Communication and intercom units - push-to-talk buttons and channel selectors with a short travel and firm click feel.

Technical Parameters

Quality Assurance

• Incoming material control - silicone compound hardness and cure rate verified per batch before moulding.
• In-process inspection - first article approval against the 2D drawing, dimensional check every 2 hours, carbon pill position verified on the moulding line.
• Electrical testing - 100% contact resistance and keystroke response test, with sampling for actuation force and travel.
• Reliability testing - life cycle, high and low temperature, salt spray and solvent resistance on request.
• Compliance - SGS, ROHS and ISO 9001 certified production, with test reports supplied with each shipment.
• Traceability - batch number and inspection record kept for 24 months for every order.

Packaging Standards

• Inner packing - each keypad in a PE bag, laid flat on an anti-static tray so carbon pills never rest on a hard surface.
• Carton - export-grade five-layer corrugated carton with a desiccant bag, weight kept under 15 kg for manual handling.
• Protection - silicone keypads are packed without compression load to avoid permanent deformation in transit.
• Labeling - item number, batch number, quantity and production date on the outer label, carton marking to your own artwork if required.
• Custom packaging - branded color box, blister and pallet packing available for retail or line-side delivery.

After-sales Service

• Fast response - every inquiry and complaint is answered within 48 hours by the engineer who handled your mould.
• Sample support - free samples from existing tooling, and paid prototype samples from new tooling with the cost credited to bulk orders.
• Drawing review - DFM feedback on wall thickness, draft angle and carbon pill layout before the mould is cut, free of charge.
• Quality replacement - confirmed defects caused by our moulding or material are replaced or credited without argument.
• Tooling care - moulds are stored and maintained for 3 years, so repeat orders start from a checked tool instead of a new one.
• Technical follow-up - assistance with assembly, contact resistance issues and legend wear after delivery.

FAQ

Q: What is your MOQ for a custom keypad?
A: 7,000 pieces per design. For a first trial order we accept 3,000 pieces of a single layout.

Q: Which files do you need for quotation?
A: A 2D drawing or 3D file, key layout, hardness, color and the required actuation force. A photo of the current keypad is enough for a first estimate.

Q: How long does sampling and production take?
A: 5-7 working days for a new tooling sample, 7-15 working days for mass production after sample approval.

Q: Can the contact resistance be lower than 100 Ohm?
A: Yes. With conductive carbon ink or gold plated contacts we reach 50 Ohm and below, depending on the circuit design.

Q: Do you support backlit keys and multi-color legends?
A: Yes. Laser etched backlight windows, silk screen legends and multi-color key tops are all available from the same tool.

Q: Are samples free?
A: Samples from existing tooling are free, you only cover the freight. New tooling samples are charged and the cost is deducted from the bulk order.
