G130 Silicone Rubber Keypad for Electronic Products
G130 is a silicone rubber keypad built for electronic products that need a soft tactile key rather than a metal button.
Product Overview
G130 is a silicone rubber keypad built for electronic products that need a soft tactile key rather than a metal button. Load pressure can be set from 50g to 500g and key trip from 0.5 to 4.0MM, so the feel is tuned to the device instead of the part dictating it. Silicone gives heat resistance, cold resistance, electrical insulation and fatigue resistance across a wide temperature band.
- Touch feel is tuned by elastic wall design, with load pressure selectable from 50g to 500g
- Operating temperature from -20℃ to 180℃ covers appliances and equipment that run hot
- Contact resistance under 150 ohms keeps key detection reliable over the part life
- Different colours and colour areas can be designed for each customer requirement
- Electrical insulation of silicone avoids the isolation work a metal key needs
Application Scenarios
- Remote control handsets
- Telephone and wireless telephone keypads
- Computer keyboard key mats
- Learning machine and digital product keys
- Password entry keypads on electronic devices
Who It Is For
- Consumer electronics product engineers specifying key feel
- Device manufacturers needing colour matched keypads
- Buyers replacing worn silicone mats in existing products
Problems It Solves
- Fixed force keypads cannot match the touch a product design calls for
- Rigid keys transmit shock and noise into small handheld housings
- Conductive contacts drift out of range without a controlled resistance spec
- Multi colour key zones are hard to achieve with moulded plastic caps
Technical Features
- Load pressure adjustable from 50g to 500g
- Key trip from 0.5~4.0MM
- Contact resistance less than 150 ohms
- Durability of 5-5 million operations
- Operating temperature -20℃ to 180℃ and storage -30℃ to 250℃
- Operation force in the 120g to 180g band
- Different elastic wall designs to change the touch feel

How It Compares
| Stainless steel keypad | Silicone gives electrical insulation and a soft stroke instead of a rigid metal key |
|---|---|
| Fixed force rubber mats | Load pressure is specified per order anywhere from 50g to 500g |
| Standard temperature rubber parts | Operating range reaches 180℃ with storage to 250℃ |
Use Guide
- State the target load pressure and key trip when requesting a quote
- Provide colour references for each colour area on the mat
- Confirm the PCB contact pattern so resistance stays under 150 ohms
- Keep the part inside -20℃ to 180℃ in service
- Store below 250℃ and avoid oil contamination before assembly
