Commercial vehicle sectional type adjusting pedal with microswitch

The invention provides a commercial vehicle sectional type adjusting pedal with a microswitch. A main arm can rotate around a slave arm; the angle control unit is connected with the main arm and is used for controlling the rotation of the main arm; when the angle control unit and the main arm are connected, the angle control unit at least limits downward rotation of the main arm pedal portion relative to the auxiliary arm, and when the main arm pedal portion rotates downward relative to the auxiliary arm, the main arm and the auxiliary arm move synchronously. When the angle control unit is separated from the main arm and the limitation on the main arm is cancelled, the main arm can rotate upwards or downwards relative to the slave arm; when the main arm rotates by a certain angle relative to the auxiliary arm, the angle control unit can be controlled to conduct connection limitation on the main arm, and the angle control unit at least limits downward rotation of the pedal portion of the main arm relative to t
