This is a fully working and proven design. The feel of the push button recall is exact and firm. You will need the following components to complete:
Qty 12 yellow 5mm led's
Qty2, 12mm tactile switches with round buttons
Qty2, m3 18mm screws.
The design is based around www.cockpitsimparts.co.uk, 6 pack decal. But I have included a version in the design.
