This version of the Eldat-Easywave RCJ01 flush-mounted receiver is used for the potential-free switching of small or mains voltage users in the operating modes on/off (1 and 2 button operation) or Totmann. The RCJ01 is characterised by its small dimensions and fits in all standard flush-mounted sockets. Up to 32 transmitters can be programmed so that even complex control tasks can be easily and space-saving. The programming itself is very simple and takes place directly on the device by pressing a button.
