The switch does not require complex wire assembly and RF transmission is powered by the mechanical actuation of the switch (8N and a total travel of 3.4mm generating two times 0.2 up to 0.5mW), which means that no batteries need to be changed or disposed. With a Lifetime up to 1.000.000 operations and rated for operation in the -40 to +85°C temperature range, each switch comes with a unique ID that excludes mutual interference between different RF-switches. Flexible pairing allows the operation of several receivers with one switch (and vice versa). The wireless range is 10m at 2.4GHz and over 300m at 868MHz (line of sight).
