Hello everyone,

I’ve just purchased this : **broken link removed**

Now what I’m trying to achieve is utilising 2 relays as momentary switches for an rc winch and I’d like to have the other two as on/off switches for lights ect, however there appears to be only one jumper port which I’m assuming will affect the setting across all relays, now my question is would I be able to somehow “create” seperate jumpers externally or even achieve this another way?

Thanks everyone
 
From the description from the e bay page, I can only assume it's as you said, with the jumpers affecting all relays.

If the jumper is on the transmitter board, you could potentially rewire it so that two of the buttons are in toggle mode. It looks possible if the circuit is like https://www.twovolt.com/2019/05/30/4-channel-ir-transmitter-and-receiver-module-using-ht12a-ht12d/

If the jumper is on the receiver, or it's not an HT12A/D being used (which I'm guessing is the case), then you can put the receiver into momentary mode, and put a dual flip-flop in-between the decoder output and the relay/driver to provide the toggle function.

If you can provide some close-up photos of the board, it will be easier to know what's possible.
 
Awesome thanks for your reply, as soon as it turns up I’ll report back with some photos, the jumper issue didn’t really cross my mind until I’d already purchased it lol
