STAHL 244633 Key Operated Switch Actuator Instruction Manual
- Pushbutton, mushroom pushbutton, mushroom stay-put button with key lock, mushroom stay-put button, twin pushbutton and illuminated pushbutton, rotary actuator, key-operated switch, potentiometer bezel and indicator lamp bezel
- One axial actuator can actuate up to four 8082 series contact elements
- Key-operated switches and rotary switches codable at any time as “latching/spring return” or “key not removable”

Thanks to their special technical features, the actuators from the 8602/3 series can withstand the most extreme conditions. In addition to the application option for use in ambient temperatures from -60 °C to +70 °C, the IP degree of protection, IP66, is maintained in accordance with EN 60529.
It is also possible to actuate up to four contact elements from the 8082 series with a single axial actuator from the 8602/3 series.
The coding option of the key switches and rotary switches is innovative and one-of-a-kind. Integrated coding allows you to adjust the “latching/spring return” and/or “key not removable” functions at any time without additional accessories. A versatile set of accessories consisting of label holders and locking devices is available.
