The "B" model used a flatted bat handle toggle switch which IIRC weren't made by C&K. I think I may have the number somewhere but I think there was a thread with this info a few years ago. A Google search might produce it. The Altair group archive on Yahoo might have it too. 

 The IMSAI uses a plastic paddle switch.
