Question On/ Off Switch recommendations

Hi guys,

I want to add a power switch near my steering wheel that acts as an emergency switch if necessary as well as an convinient way to power on or off the motion rig.

I run a 24v system so I struggle to find "correct" switches for 24v.

I thought about something like this :


I figured I put it between the psu and the sabertooth which should work as desired.
My question is what I might missing and what do I need to take into account?

Oh it looks like the link was broken for the reference.
I was looking for more of a racing look:

But all I found were for 12v only.
I can't use a 12v one for my 24v system, can I?

To control the high current out of a Sabertooth you would want the switch in your cockpit to just energise/de-energise a suitable high current relay. https://www.ebay.com.au/itm/12V-24V...610d770bd:m:mDrq_UPX7OEo9fLUfx0KLpg:rk:2:pf:0

Also if it is going to be used to shut down your drive motors in a emergency, then I would recommend a standard emergency switch so that it is easy to hit if you are maybe being thrown around by a runaway system.

Thank you for pointing that out.
That's the reason I was confused I couldn't find any switches that are rated for more than 2A.

I should have listened more carefully back in physics class...

Thank you all for your answers, my question is hereby solved.

I thought about the last point as well and might be better of with a common emergency switch.

Como su nombre indica es una parada de emergencia, es mucho más fácil de activar que un interruptor de palanca

I'm sorry but I don't speak Spanish.
Might you be able to repost your reply in english? So others could follow along too?

As the name suggests is an emergency stop, it is much easier to activate than a toggle switch

The load capacity of a contact camera of which I use is 10A

Also if you are using a Sabertooth 2x32 you can use the built in emergency stop by enabling dip switch 6. More info here and in the manual.

effectively

I've read the sabertooth's manual like a hundred times by now and I dare to assure you this paragraph did not existed before you pointed it out to me!

Thank you, anyway!

I don't know how much current your rig uses, but I would directly cut the main power with a contactor (read high power relay here). The contactor is controlled with a low power signal, so you could use any switch you want and still be safe (I would suggest a E-stop switch anyway).

I personally feel more comfortable with an emergency switch that physically cuts the main power coming into the system instead of relying on relays, and software controlled e stops. I have an emergency switch meant for large stationary power tools (table saws) wired in line with the AC supply coming into the system. The switch is identical to this one:

I have a Rockler version of the same which has built-in cords and just plugs in like an extension cord.



The "STOP" paddle swings loose and could make annoying noise during motion. There's a regular button underneath so you could just remove the paddle, but it would be harder to push in an emergency so I put a little 3M COMMAND hook on the back side and then strapped it down just tight enough to keep the paddle from swinging away from the button.

The "socket" cord is also pretty short, but that can be solved with another heavy-gauge extension cord.

I wish I had seen a pre-wired one before I installed mine. Would have made it a lot easier and with the extra cable/plugs I had to buy it was likely cheaper too...
