A start-stop deactivation of automatic switches is offered for a Smart Fortwo 451 MHD.

- Easy installation
- No need to press on the Eco switch
- Protection of the start-stop alternator & front cover

After the engine starts, a switching pulse is automatically generated that switches off the MHD mode.
Switching (activation) to MHD/Eco mode is done by pressing the switch.
A reversing circuit is thus implemented.
(The eco switch shown in the picture is not included as it is already installed in the vehicle.)
