The front panel switches have been the most difficult component to source.
C&K, the original manufacturer, as well as many others have discontinued the J4-style paddle switches.
Many years ago, NKK introduced a beefed-up version of the C&K with the J4 paddles.
These switches are still available but have two drawbacks.
They’re very expensive, and the blue color is not a good match to the C&K blue.
Another clone of the C&K were introduced by Alcoswitch and E-switch.
You can sometimes find these on the surplus market and eBay.
While the paddles are an excellent match for the C&K, they are subtly different and are not interchangeable with the C&K paddles.
We found a reputable switch manufacturer who cloned the Alcoswitch. These are the switches we use in IMSAI front panel kits.
We think they're actually better than the C&K:
Because these new switches are not an exact match to the C&K, we do not recommend mixing these in with other switches − even the original C&K.
If you must replace a switch or two in an existing system, the best option is to replace all of them with new ones.
