To protect operating functions against unauthorized actuation, Rafi offers a key-operated switch from the 'Rafix 22 FS+' range of control devices with a height of just 45.1 mm in front of the front panel. The switch is available in versions with momentary and latching contact functions and with four different rotation angles. With IP65 protection, the key switch is protected against water jets. It is designed for installation openings with a diameter of 22.3 mm and a grid dimension of 35 mm × 35 mm. It is mounted using a threaded ring. Front rings in different colors and metallized versions are available to identify the function. The key switch can be combined with PCB switching elements for PCB mounting or with QC switching elements for wired direct connection.
