Editing my review as I previously thought these were true bi-stable relays (i.e. they remain in position until flipped and do not use any power unless the position is being changed). This is not correct. These modules actually use regular relays, meaning if power is lost when the relay is in the closed position, it will reset back to open. This also means that continuous current is required to hold the relay in the closed position. Probably not very much, but generates some current draw and heat nonetheless. They do work as expected however.These units are smaller than they appear in the picture, so you can fit them into a small project box without difficulty. They are attached together but can be easily separated if required.One point to note is that the trigger is activated when it's shorted to ground. So your trigger switch needs to be connected to the negative power terminal, not the positive. This is not immediately obvious when looking at the diagrams.
