Smart ED & EQ fortwo and forfour from 2017 to the end of 2019 have a switchable sound generator installed. If you switch it off, it will be on again the next time you start the vehicle.

This module detects when the vehicle is started and "pushes" the switch by giving an appropriate pulse on the switch's wires. If you need the sound generator, you can still activate it at any time by pressing the button.

The switch itself and the terminals to connect it to the vehicle are supplied. It doesn't need to be soldered. Installation instructions are also included. This is very easy and requires no prior knowledge. Everything is clearly described and explained with photos.
