Dimmer 2 Toggle Switch Query





I'm new to Fibaro, just planning at this stage.  I have a question regarding the wall switches used to control the Dimmer 2 (FGD-212).  I have searched the Forums but can't find an answer.  I would be using a 3 wire connection and in the manual the switch is wired between S1/SX.  My question is, what rating/voltage/current are at the S1 and SX terminals during operation?  Is it a voltfree switch?  Is it 240VAC?  I take it doesn't have anything to do with the load as a normal light switch does, as it can be a toggle switch?


Many thanks,

  • Thanks for the quick reply.

    I read that using LED bulbs may require a bypass 2.  I've also read that if wired in the 3 wire configuration, the bypass is not required despite using LED bulbs.  This doesn't seem to be clear in the manual either.  Does it need a bypass 2 if wired with the neutral with a load of lets say 25W?


    Thanks again.
