The following are parts that I have extra of as a result of repairs or projects. In most cases I was required to buy a larger quantity than I needed (sometimes by quite a lot) in order to find an identical replacement part. The parts can be ordered by PayPal. Email me.
I did not take all the photos, but they are always representative of the part. |

JD S-Series Keylock Switch, 3, 5, 7, 9 Position - New with keys I have boxes of these from way back when.
I'm not sure if they are actual APEM or knock-offs or what. There are no momentary positions. They all click into place. Key B001 - 3 positions, Key B002 - 5 positions, Key B003 - 7 positions, Key B004 - 9 positions (goes all the way around). |
$3.50 each | 100? |

C&K, C & K - L Series Miniature Slide Switches. Part Number L204-09-1-MS-02-Q same as L204091MS02Q This is a DP4T CK slide switch, PC mount with a 0.25" actuator height. Very similar to L204011MS02Q and L204121MS02Q. See this page for comparison. It's possible these might work for a Pro One or Octave Cat, but you have an extra position or two that you'd just cut the legs off of I imagine. I've never tried that, but I have so many of theses, it's a waste to see them sit around. | $1 ea | 1000 |
