Switch question
Does anyone know of a 3 position on-off-on Pico/battle type switch that I could pair with the 3 position switches on my transmitter? I'm almost done building what I need using servos and roller switches, but I'd still like to find an easy electronic solution if possible. I assume something could be done with Arduino, but I'm not going to be learning that anytime soon. Thanks!

Re: Switch question
Has Dimension Engineering stopped offering the Pico or Battle switch?
What are you attempting to do with it? Any small 10A esc would work the same as a DPDT switch, just takes up a little more space than the DE switches. |
Re: Switch question
The Pico and battle switches are still available, but to the best of my knowledge, they're just 2 position switches (on/off). Using a 3-position switch on my transmitter, I want to activate a solenoid valve when I throw the transmitter switch in one direction, then activate a different load when I throw the switch in the other direction. In the center/off position, both loads are off. For now, I'm mounting two roller switches next to a servo and will use the servo horn to activate the switches, but I'd like to find a simple electronic solution so that I don't have to worry about aligning/adjusting the roller switches.

Re: Switch question
would these work.

Re: Switch question
Thanks for the links Jerry! My transmitter already has a few 3 position switches. The issue is on the receiver side - finding a 3 position switch that can be used in conjunction with the 3 position switches on my transmitter. It all boils down to conserving channels. I could accomplish what I want using 4 Pico switches and 4 channels, but I really need to do it using two. For now, I can certainly continue down the path of mechanical switching using servos and roller switches since I almost have them built anyway. I just wanted to see if there was any easy electronic solution. Thanks for looking!

Re: Switch question
The Battle switch is a single pole double throw, so it will do the job what your mechanical switches are doing with less wiring.

Re: Switch question
Thanks for trying to help out with this! I actually reached out to them last week and they confirmed that their Battle Switch (SPDT) and their Double Switch (DPDT) wouldn’t work because they are both 2 position switches and they don’t carry anything that’s 3 position.
Here’s a picture of one of my mechanical servo switches ready to go. Switch one controls a pump. Switch 2 controls a solenoid valve. In the neutral position, both switches are off. When the servo rotates counter clockwise, both the pump and the solenoid are activated. When it rotates clockwise, just the pump is activated. [IMG]https://i.postimg.cc/PJSKWfPw/Tg049.jpg[/IMG] |
Re: Switch question
pretty slick...
Of course it's only temporary ... unless it works... |
Re: Switch question
Very nice servo switch!
I don't know if this helps, but if you wanted to replace it with an arduino nano or something, the following code should in theory emulate it, reading one radio channel and switching two outputs. I just wrote it, but I haven't tested it. You could add a couple more channels. Note that the arduino can only output signal levels of current, less than 20mA per pin, so you'd need some transistors or relays to actually switch the solenoid and pump. Or hook up small esc's or servo boards (or battleswitches?) to the arduino and control those with the servo library instead of switching the outputs high and low. Code:

Re: Switch question
Thanks so much for doing that! Learning arduino is something I’d definitely like to do some day, but it probably won’t be for quite awhile. In the mean time, I just found a couple of these dual relays for $10 each on eBay. They’re exactly what I needed. With the transmitter switch in the center position, both relays are open. Throw the switch in one direction and one relay closes. Throw the switch in the opposite direction and the other relay closes. Thanks again!!
