one more question :) i have used only one relay and used the toggle fuction for up & down. does it mean i'm using electricity all the time? or is it just a matter of having 2 diffferent buttons one for and one for down?

I do not know what you mean but your relay needs to be constantly under tension that is connected to AC power. You use only one button on your device because it allows, I mean one share of a button. If you press once it spins to the left and press the second time the engine turns to the right. Probably the machine that goes out only 2 wires? "I'm sure. The opposite of this is for example the engine used in some blinds which come out 4 cables (but you control only 3 cables because 4 is grounded)so you have two relays where one controls the engine to the right and one left so if you give the command to separate buttons.
Edit.
Not because it consumes electricity shut off relay it to you after each command that is to say there is no engine power. So requests because I do not know what device you use.

Then you have not red the posts above enough well because it was explained how things should be wired. Please read again and read other posts about the relays on the forum. All has already been discussed.

NOTE: the wiring on the provided link is missing a protection diode that should be (optional but recommended) used on the driven relay. If someone doesn't know what this means it's probably better that this user should not wire things by himself.

yeap your right, i didnt understand it when you mentioned the 5v but thru searching i found a guy that had the same issue and figured it out what you meant. so thanks for the help!
