For home and building technology, Cherry presents an energy-autonomous wireless switching module that is not dependent on the ambient temperature or the frequency of actuation. The modules can be installed encapsulated and have no mechanical connection to the outside world. According to the manufacturer, they are therefore also suitable for adverse operating conditions in the field. An inductive pulse generator converts the mechanical actuating force of the operator into an electrical energy pulse. This pulse contains the basic electrical energy, which is converted into a constant supply voltage in the energy management system and stretched over time to supply the radio electronics. The product range extends from the generator module to various housed radio switch variants. In addition to snap-action and rocker switches, a ready-to-install radio light switch module is available for the KNX-RF standard. The range of the transmitter is up to 30 m in buildings (868 MHz band).
