  • radio transmitter arrangements have switch contacts, which can be closed by a rocker switch or a switch handle, and with which an input or a command can be applied to an electronic circuit arrangement.
  • the electronic circuit arrangement controls or comprises a radio transmitter with which a radio-controlled control signal can be emitted in order to control a radio-controlled actuator in order to switch or control a consumer connected thereto.
  • radio transmitter assembly For the acceptance of such radio transmitter arrangement on the market, I have found it advantageous to accommodate such radio transmitter assembly in surface-mounted housings, which resemble in their form the known switches or cover frame of a house installation assembly for flush mounting, making such radio transmitter arrangements in a household not externally of conventional switches or Buttons can be distinguished, however, continue to have the advantage that for their installation no caulking and cables are required, and a simple displacement of the switch is possible.
  • this limitation to a very small housing volume and a very low housing base and height leads to problems with regard to the accommodation of all components required for operation.
  • the arrangement of the actual switching contact pairs within this, designed as a switch or button, radio transmitter arrangements is largely predetermined due to the mechanical conditions in such a radio transmitter arrangement. As a result, there is only a small amount of room left for accommodating the other components, such as an antenna.
  • the intended functionality of the radio transmitter arrangement can be ensured in the case of different operating states which arise, for example, through the actuation of different switching contact pairs. It can thereby be achieved that the desired tuning of the antenna is not influenced by the construction and operation of the radio transmitter arrangement.
