Well, the little bots have spawned a bit of creativity

Here's gen 1



And here's gen 2



It adjusts just like a wyachi, has several mounting options and the deans ultra can handle 100/200 amps



Overkill for a little bot, but under 12 grams and small enough to fit in a quite a few locations, while also protecting the contacts from shorts.

They are perfect for our little bots, space wise, plus I can also install an led if needed, in that none of our esc/receiver lights are visible from anywhere.

I am hoping that maybe Will can produce them in quantities that are affordable.... Will??

I hate production work.

A modified 2 contact version might be good for you guys looking to turn power on from 2 differnt sources

Woah! Very cool!
I hate to sound dense, but I just want to be sure: This drives a dean's connector together/apart by turning a screw?

Ironically, I suggested to the Ransom students that they look into this approach back when we were trying to figure out a way to switch 8 seperate circuits simultaneously. They never 'took the bait," and so we ended up with only two circuits and Whyachi got more of our dough. (Admittedly, it did work just fine, and we didn't have to put much time into it)

Anyway, this is a GREAT solution.

If this were manufactured for sale, I would recommend either pre-soldering leads on the connectors, or making them out of the pre-soldered Deans pigtail.

Question-how did you remove the parts to put in the screw/'nut'? (I'm guessing you used heat, and took advantage of the Dean's tendancy to melt and misalign if overheated) If these do NOT end up in mass production, then I would love to copy this idea for Ransom's 'bots next year--so can we? huh? pretty pleease?

Nope

The switches can be completely assembled or disassembled without heat or anything else. The deans contacts can be oushed out of the housings quite easily.

You can solder to the deans contacts either before or after assembly.

I just put one together with 16 guage wire and soldered after the switch was fully assembled.

I'm hoping that Will might come forward and mass produce these or send to china for them or whatever. Otherwise I'll pobably make a batch of 25 or 50 on a first come basis if there is any interest.

Feel free to steal...oops borrow whatever you like, but there is a little more to them than meets the eye.

They are really cool...if you want to see one, just give me a call and we'll meet up sometime....I'm in south Miami cel: 954-680-2009 name is Richard

oh boy! that looks much better than the first generation!! Sounds like Alex and Tyler wouldn't mind making some of these, so I'll give it a shot! I'll need one to get the dimensions, design it in Solidworks, and have a mounting system for it. Do you think that you could send me one? We could consider it payment for the gears and the switch housing! Laughing

I've got one with your name on it!!! well...I just need to make 1 part for it.

I won't need the switch housing right at the moment, tho....

So when will you be back in town?

I may still need to use gen 1 or some version of it on my little drum bot, if I need 4 or 5 grams of fluff to make weight....lol

Give me a call when you get in and I'll have a switch and a solidworks file for you as well...hope you're having fun!!!

btw: nice to have Bob Dubard on the forum....

oh...and the switch does have several mounting options built in...if that's what you were refering to???

They're just hard to see in that the polycarb is clear
