I currently have a number of 12v led drivers available as in the picture I also have a 5v regulated power supply which is powering some ws2812 leds nearby, I think this was 5v 10amps, the current project is only using 3amp from that psu, so either of these power sources are available

Hello,

Im really sorry im confused on this topic can someone help me find a relay for the following job please? I have a touch sensor connected to an arduino, when pressed I need the arduino to switch a relay which turns on 12v leds, I need the relay to stay switched on (leds stay on) till the switch is pressed again? Not sure if the arduino is even needed in any of this but I dont know enough about electronics. Could someone help me find a suitable relay for this please?

Thank you

So why not use the device I posted in #11?
