After making a ZY-T08 custom driver with dual switch support I’ve kind of gotten hooked on the functionality dual switch lights. And ever since I saw FmC’s S2+ mod with a side switch ([Mod] Convoy S2+, plus...) I’ve wanted to build one to use with my firmware, especially since I made it ATtiny85 compatible (Custom dual switch driver finally seeing some light.).
Doing it on the S2+ was not appealing as it looked like a lot of work, and FmC wasn’t taking orders either, so I set my sights on the S3 as it has the integrated shelf (no pill). I had a whole bunch of different momentary switches to try out with the intent of mounting the switch inside the light and have a pin like FmC did, but it was far too tight inside the S3 to work, so I went with having the switch on the outside like Firelight2 did here: [Mod] Convoy S2+ Mini - triple XPL with sideswitch *opinions needed*
The driver of choice: My new design with a PSMN3R0-30YLD FET and 8 x AMC 8135 (4 channels: 1,2,4 constant current and 1 for PWM between):
Stiff copper wire over the MCU instead of a spring to add space. Also a bit of that copper wire to bridge the solder pads for the channel configuration I wanted. I had to file out the retaining ring a little to get it on.
Drill a hole for the side switch wires and mount the Triple XPL-HI 5000K (to be used with Carclo 10507 optics). I did blow it clean with compressed air before mounting
Put the light together with the switch on the outside:
I covered with tape to test, thinking what I was going to do to cover it up, maybe like Firelight2 did:
Not happy… FmC’s mod is far more appealing, mine just feels sub standard, I gotta do something better than this… So I ravaged through my stash of switches, looking at some I first discarded and found one that gave me an idea. The first hole wouldn’t cut it, I had to drill another a little further to the front, and bigger. Drill through with 5mm for the wires, and almost through with a 7mm drill, leaving a shelf for the switch:
I hit the inside of the shelf just as planned, so aiming was good. It was necessary as I needed some clearance from the back of the driver board.
Now I could solder the wires to the switch on the outside, not having to work in that tight confined space:
Now I just had to put a little glue on it and shove it in so the switch rests on the ledge I left. Now I’m happy! This is much more looking like what I wanted to achieve:
I’ll be on the lookout for a perfectly round switch, that would be the icing on the cake, but this is much cleaner than having the switch on the outside. So now I have my Convoy S series triple with dual switch setup :party:
