    I need to make an auxiliary cable for a microswitch. The microswitch is mounted on a Packard pneumatic shutter & is used to trigger flash sync. The posts on the switch are ~1.5mm O.D. & the supplied cable has 2 push on connectors that go over any 2 of the 3 posts. I need to know what this type of connector is called & could use suggestions on where to purchase similar connectors. I've already tried Radio Shack & the local computer repair shops with no joy.

    As a photographer, you should know how to take a well-lit, in focus, macro picture without speed blur. ;)

    Gee, thanks for the help. It's a crappy iPhone photo because its sole purpose was to show the microswitch — not to dazzle someone with my artistic & technical prowess. Now if you'll excuse me, I'm going to go mix some darkroom chemicals.

    I couldn't tell it was a microswitch, which was kind of the point. I believe the switch manufacturers sell a connector and wire harness to fit.

    Incidentally, the posts are about ⅜″ apart, center-to-center. I have made enquiries with various electronics retailers who sell similar switches & they don't know of any connectors like the ones I pictured in my 1st post. Most of their end users are soldering permanent connections. But that's a no go for me; I need to be able to detach the cable when the shutter is not in use.

    Posting the solution, in case anyone else is looking for this connector:

    I wrote to Packard Shutter, who identified the connector as an AMP product. I asked for clarification, but got no response — however, a Google search lead me to TE Connectivity. I made an enquiry with them and they were unable to match the product, but told me that the microswitch connectors were of the type known as "bullet terminals." A search on that led me to Digi-Key, where I found the connector, which, it turns out, is at TE/AMP product.

    Package arrived this morning. The connectors are a little tight over the terminals, but they will definitely work. I'm waiting on the arrival of a cable from Amazon that I can cannibalize/convert tomorrow.

    If you disconnecting a lot, consider the CPC Series 1 connectors: http://www.digikey.com/en/product-highlight/t/te-connectivity/circular-connectors

    Unfortunately, they do require crimpers and a removal tool. The pieces have gone up significantly an dyou have to buy each piece separately; pins, housing; seals; strain reliefs. They are also available in std sex and rev-sex.
    The crimp tool has gotten out of hand too, but you can find cheaper ones.

    I made stuff for our in-house use in a lab and used a lot of these. One reason is they are re-useable with nearly no effort, but during my tenure, I never reused one.

    Then there's the possibility of a switch?
