• Korry Latching Switch

    Tutorial Present By member Per-Erik

    Per-Erik, our member explains his simple DIY technique to build a "Korry-Latching-Switch". Seems to be a simple and effective solution.

    This has certainly been done before, but I would just like to show you one way of making a latching switch. Though I have a CNC, it is not necessary to get this to work, but it helps a lot. I was looking for a latching switch with a travel of 7-9mm, but that was not easy to find so why not use a ballpoint. I have not touch the original Korry 433 or some of the other 1 Korry stuff, but if you look at a ballpoint I believe its action is quite the same as the Korry. With some modification and in my case adding a small PCB, I ended up with this prototype.

    The PCB is carrying a Microswitch, two LEDs (not mounted), three resistors and a transistor (for light intensity control)
    The nice thing is that the Microswitch with the Lexan spring gives me a true state of the switch toggle action.
