ICR stands for Inner Contact Rubber is a product which has switch function (ON-OFF) forms electrical continuity part on the silicone rubber.
Feature
We design stroke and skirt form of the button based on particular repelling force of silicone rubber, and provide parts at customer's target force and click ratio .
| Type | Type | Features | |
|---|---|---|---|
| a | Contact Printing | 100Ω ≧ | Low Cost / Can design contact shape circular, oval and quadrangle |
| b | Carbon Pill | 100Ω ≧ | Lower Cost comparing with metal pill / Contact shape is only circle (φ2, 2.5, 3, 3.5, 4, 5,6,7,8) |
| c | Metal Pill | 2Ω ≧ | Low Resistance / High Reliability |
*Resistance value ≧ 2.5φ of contact printing area is set ≧ 300Ω.
Application
| Steering Switch (in-car Use) | Audio Switch (in-car Use) |

Development Flow
Upon receipt of your design information, we suggest the most optimized inner rubber contact switch design by following the development flow. Contact Polymatech today for your complete application solutions.
 |
 We suggest the best design considering operation force and stroke by use of FEM. |
 We make tooling based on simulation results, and manufacture ICR by way of trial. During trials, we verify F-S features e.g. adjusting rubber hardness, and make samples considered target operation force and click ratio. |
