Iambic Paddle Key

The CWMouse Paddle Key has a very positive feel and no false symbols. You’ve never used a paddle like this before. Imagine crisp mouse button action or mechanical keyboard in a paddle! I built it for me, but I’m selling to everyone looking for a lightweight and precise paddle on a budget price!

CWMouse Paddle Key reviews on eBay and eHam.

It is designed in FreeCAD and pre-assembled from seven 3d printed parts:

• main case
• top cover
• 2x paddles
• 2x paddle bottom posts
• micro-switches tray

Additionally, following components are used in the assembly:

• three machine bolts
  • threaded into paddle rotation axes and to hold top cover
• four sealed ball bearing races
  • snapped into their holders in main case and top cover
• two sealed micro-switches
  • glued into micro-switches tray
• an audio jack
  • glued into the main case
• rubberized compound for paddle movement dampening

Dimensions:

• enclosing volume: L:74mm/2.9in x W:36mm/1.4in x H:28mm/1.1in
• weight: 45g/1.5oz

Notes:

• due to micro-switches closing the circuit, the throw is not adjustable
• due to micro-switches providing spring action, the tension is also not adjustable
• having said that, the geometry and tension forces are optimized for a good feel
• if you like more throw in your paddle, you’ll love this one - it has 1.3mm or 3/64in of movement from rest to fully bottomed, but switches activate at approximately 0.5mm or 1/64in
• there are no magnets in the base as this is a medium sized portable paddle meant to be hand-held
• due to use of 3d printed material, it should not be stored above 100F (sorry Arizona folks)
• due to use of 3d printed material, it is normal for there to be very minor variations in surface finish
• all paddles are tested for proper operation before shipping
• Made in USA by KN6FQM :)
