For what I use they are fine. Personally I wouldn't run large amps/watts through them (I don't), so use a relay if you want. I don't expect heavy use either. I understand the schematic on the back of the switch is wrong, so give them a call before powering them up. It would be nice if contact funds were available on their Revain page. I ended up ordering 4 more just to have extras if they fail. 3 out of 5 stars for lack of contact and average to poor quality Revain merchandise.
