Product Overview
Custom elastic buttons for automotive controls need to suit the location and direction from which they are operated. Molded dimensions, colors, and identification can adapt the visible layout, while the conductive arrangement must align with the electronics beneath it. The housing and keypad should be developed as an assembled control.
Consider the approach to each button in its installed position. A control reached from the side can experience a different press from one operated straight on. Button spacing and support should allow the intended action without catching adjacent keys or holding a contact partly engaged.
Select the material for the local environment, including temperature and substances encountered during cleaning. Place printed or molded identification where it remains visible in normal use. Evaluate the complete assembly after fastening the housing, since its supports influence key travel and return.
During installation, keep the contact area clean and locate the keypad before closing nearby trim or case parts. Check every function afterward, including keys at the perimeter where support may differ. Preserve the original seating arrangement when the control is opened for maintenance or a matching keypad is installed.
- Material options
- Rubber. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. Evaluate the complete assembly after fastening the housing, since its supports influence key travel and return.
- Custom dimensions
- Molded dimensions, colors, and identification can adapt the visible layout, while the conductive arrangement must align with the electronics beneath it.
- Fit & assembly
- Check every function afterward, including keys at the perimeter where support may differ.
- Use & inspection
- During installation, keep the contact area clean and locate the keypad before closing nearby trim or case parts.
Photos illustrate structure or material only. Button spacing and support should allow the intended action without catching adjacent keys or holding a contact partly engaged. ETOL directly manufactures custom-shaped silicone and rubber parts to your requirements.

Ordering this custom component
Can the shape be adjusted to my mating parts?
Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.
Which details should be agreed before tooling?
Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.
Can a sample help define the replacement?
A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.
How is the quotation for this part determined?
The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
