Finger gestures instead of mechanical buttons, keys, or dials: For the 12.81 timer, FINDER uses the smartphone to program this type of device. NFC is used as the interface for this patent-pending process. Near Field Communication makes it very easy to communicate between smartphone and electronic device.

Apps for the smartphone have the charm of being clear and intuitive to use. FINDER has brought this convenience to the 12.81 time switch via NFC. The device for the standard rail can be completely configured with the FINDER app on the smartphone. Once the work is done, the data set is transferred to the time switch by simply placing the smartphone on the device housing. The data transfer also works without a power supply at the timers, because the smartphone itself ensures via induction that the NFC chip is on reception. Consequently, a time switch can be conveniently configured in the office after unpacking and is then immediately installed in the distribution or control cabinet ready programmed.
