low profile momentary switches NC - source?

[lcipher3]

Anyone know a place I can get low profile momentary switches? Only need a ON-(OFF) ie normally CLOSED momentary since it for a BOSS pedal CTRL1 and CTRL2 input.
I don't want a "tall" enclosure. The "XWING" types would work switch-wise but Im looking for a little shorter. Something that would mount in a box that's less than 18mm tall (0.70 ")

I do have a solution to use an old ROLAND FC100 and hack it up and use a relay to get the NC action with their tactile low profile 12x12 NO switches, but looking for a simpler solution. Hard to find NC momentary switches. I've not found ANY 12x12 tactile switches that are NC hence a relay or something. Incidentally I was surprised at the speed of these relays. Approx 1msec from trigger to relay contact. Anyway....

Get an actuator as below, add a tiny magnet to the plunger, and put a NC reed switch underneath:

I posted a thread some time ago about making low profile footswitches, you might want to find it and take a look.

EDIT: here's the old thread i was mentioning

Thanks - yeah that might be the way to go. Didn't think of reedswitchs
REED SWITCHES

The actuators are a bit pricey and hard to find in the US. Digikey and Mouser have some but $$

Some time ago acutators were available on aliexpress, but they evaporated. And so far no offers, I check regularly.

I bought mine from the link I posted above (Banzai Music in Germany). They're about 2 Euros a pop and shipping to Canada is around 9 Euros. I didn't find that expensive at all, but I did buy a couple dozen, so shipping became negligible.

I wonder how this last one installs in a pedal. Looks like it needs a huge hole for the plastic piece, but allows LED lighting. Intriguing...

Kinda looks like the same as the others with an added clear shroud
I wonder if one of the cheap chineseium momentary switches could be disassembled and used.

Hmmm. Not the case here.

thanks! shows up in US - too bad there isn't dimension specs. The Daier footswitches are usually 8.8mm dia on the plunger vs "normal" of 10mm but not a big difference

I may have to experiment a bit. I have a bunch of Roland(BOSS) switches that are used with tactile 12x12mm switches that could probably be used with the reed switches.




And the "XWING" style (broken ones I have) come apart and might be able to be turned into an actuator.

thanks missed it

good image from mouser on the alpha part that they sadly dont stock

This switch style ought to be jerry-riggable into a self contained low profile reed switch contraption. A little PCB with a reed on it instead of the original body, some plunger with a magnet inside, reuse the X (or rather Y) clips for fastening, and behold! A new pedal part is born. I've been thinking about this for a very long time but I'm just too lazy. But some manufacturer should pick this up. A forever switch!

yeah the 'self contained' is what makes it attractive with the clips. Only challenge is attaching a magnet to the plunger. The xwing plungers at the tip are only 2mm dia vs the 4mm on the "actuator". But I see they do make 2mm dia magnets, and I could "stick" that to a 4mm , etc lol. Or just get out the old JB Weld and try it.

Lots of possibilities with the XWING with the real estate and clips to hold stuff. There's a decent bit of travel in the plungers. Im wondering for a normally closed switch but the switch "near" the magnet (close) and when the footswitch is activated it moves the magnet AWAY {open). By correctly positioning the reed I could go NC or NO using a "normally open" switch.



There are NC/NO (3 pin) but they seem to be very fragile "glass" vs a NO that is more robust plastic/epoxy.

how would you keep making profit without planned obsolescence though!?! Terrible idea!

All fun and games until there's a huge sub under the stage and none of your pedals will engage.

Where did you get your reed switches (brand, etc)? I was going to order some cheap ones off amazon but the reviews are sketchy in terms of failure rate/quality.

Are those "Coto" reeds? Coto makes great relays.
