Flexibility with cost and energy efficiency offered in pushbutton module

Huge topics of discussion within the lighting sector include sustainability, low-cost systems, energy efficiency, connectivity and convenience via flexibility. One solution to meet these issues is the wireless and battery-free RF pushbutton module produced by ZF.


The company offers a sustainable alternative to cabling based on RF and is free of batteries and wires. This concept removes the disadvantages of wired and battery-powered systems. A tiny and compact generator (20.1mm x 7.3mm x 14.3mm) creates enough energy by pressing the button utilising induction so that it can reliably transmit RF commands to a paired receiver. As a wireless solution, it ensures flexibility and the opportunity to retrofit easily according to individual demands. As a battery-free solution and with a lifetime of 1,000,000 switching cycles, maintenance and disposal needs of battery replacements can be circumvented.


The RF light switch module is claimed to be the only one which is directly compatible with the RF standard KNX-RF, and it supports the RF standard EnOcean3.0, too. Together with onsemi, the company has published a reference design for an Energy Harvesting Bluetooth5.0 Low Energy switch and a first demo light switch module. It is compatible with standard frames and may also be combined with customer-specific control and design panels.
