Engine switches and buttons

Engine switches and buttons – power unit control in buses

Reliable engine control is the foundation of every operator’s work. In the engine switches and buttons category on the Peterbus.pl marketplace, you will find a wide selection of buttons responsible for starting, stopping and diagnosing the power unit. We offer components designed for 24V systems, adapted to operation in demanding conditions and characterised by the highest reliability.

The Peterbus range includes:

• START/STOP buttons: Main buttons for starting and switching off the engine from the driver’s cockpit.

• DPF regeneration switches: Switches that allow manual initiation of diesel particulate filter regeneration in modern Euro 5 and Euro 6 engines.

• Engine compartment start buttons: Specialist switches installed at the rear of the vehicle, essential during servicing and diagnostic work.

• Engine speed control switches: Buttons that allow the engine speed to be increased when stationary, for example to build up air pressure in the pneumatic system more quickly.

• Components for premium brands: Original switches compatible with VDL Bova, Mercedes-Benz, Setra, MAN, Scania and Solaris models.

Our engine buttons mainly come from the dismantling of original vehicles, ensuring full compatibility with the CAN bus and ECU controllers. We check every used switch for operating precision and contact sealing – particularly important for buttons installed in the engine compartment and exposed to high temperatures and contaminants.

A faulty START/STOP button or DPF switch may prevent further driving or lead to a costly exhaust system failure. If your switch responds with a delay or has suffered mechanical damage, Peterbus specialists will help you select the correct model based on the part number or the vehicle VIN. Choose professional electrical equipment from Peterbus and maintain full control over your bus’s powertrain.
