Would a relay such as this below be suitable for switching 1.2v LED solar lights (on their own circuit separate to the controller) on and off individually. Probably a bit of an overkill in its capabilities but if it works.
Thanks
it would work.
however. relays are mechanical. they will fail if used too much or too frequently.
great if you want to turn lights on once a day. horrible if you want to have a light chase sequence.
consider a mosfet or transistor .
