ON/OFF switches can be used to manoeuvre electrical, hydraulic or pneumatic ON/OFF
functions. Examples of functions :
• Stopping and starting of the vehicle’s motor, throttle lever, beep / signal, change-over
valves, function changing for ex. 9th and 10th function.
• Enable parallel running of two or more valves at the same time from one manoeuvre lever.
• Connection of so called hold function, i.e. "lock" a function at a specific speed, after
which the speed is kept constant without the lever having to be held ( for example
hydraulically driven drills ) etc. This can be compared to the speed control in a private car.
Make sure that you always know which functions are connected for ON/OFF manoeuvring.
