Description

Keyboard button: backlit with integrated 2-colour gauge LED

Adjustment gauge LEDs coupled with rotary switch position

Exchangeable label sticker – backlit

Mechanical rotary switch with colour sticker

Panel mounting on steering wheel
• Requirements on the mounting system (apart of fixing function)
• maximum protection of panel when handling of the car
• minimum weight
• simple steering column cable
• quick mounting and dismounting from steering wheel (steering
wheel arms cannot be modified – FIA WRC regulation)
• Rear cover shaped to be centered on steering wheel – actually designed
for Sabelt Ø330 mm and larger, can be adjusted on request.
• Fixing on steering wheel by cable ties

Keyboard layouts, shape
• Layouts (button colors and symbols) can be modified to the customer requirements
• Standard layout is supplied with empty fields
• Sticker set is supplied with SWP-WRC3.1. If required, stickers can be already placed on the membrane before delivered
• Larger quantities can be supplied with graphics on membrane applied by seriography
• Relief of buttons can be heighten by applying silicone caps on the top of the buttons (height up to cca 1.5 mm)
