The pressure point is a mechanical resistance during the actuating pedal travel. This provides the user with added physical signals about the actuator position (tactile feedback).
The pressure point applies when using two contact elements with differently adjusted forward travel (two-stage switch)
Pedal pressed up to pressure point: Switching position for first contact element
Pedal pressed as far as it will go beyond the pressure point: Switching point for second contact element. The first contact element remains switched on.
