Using arduino relay for pump switch

Hi,

Has anyone had success using arduino relays with RXs? I am looking for an alternative pump switch for my cruiser and came across this guy. The coil triggers off 5v, and it can switch 10a at 12v, which should be plenty for a cruiser. Do you think this would work? It is 2.50€ (About 3 dollars)). Would the signal from a RX running from a 4.8v battery be enough to trigger it?

 

Eh. No. The signal from the RX is PWM, not a solid 5v signal.
for switches, a lot of people use these.

I would get one and try to see if you can get it to work///// Pololu has this variation
Pololu RC Switch with Relay (Assembled)

 

Does Pololu also have a switch suitable for firing guns? I saw these switches before but not sure I could get them as I live overseas…

I use these on all my guns.

 

Thanks!

I found a distributor in Spain, I will order a couple of the firing boards and the switches and give them a whirl.

Cheers!
