- The installation of the ignition switch should take into account the requirements of dust, water and shock resistance.
- The ignition switch is typically fixed to the steering column. The installation must take into account ease of use, operation for the driver and complete verification of the ergonomics. When the key is inserted into the ignition switch, it is convenient for the driver to start the engine.
- At the same time, the ease of dismantling and installation must be satisfied in terms of the fixed structure. The convenience of after-sales maintenance must be taken into account.

Magneto (M)/CDI (Ignition)
Connects the ignition switch to the engine's magneto/CDI unit (powerpack) to create the spark.

Kill Switch/Ground (M)
In the "Off" position, the switch grounds the magneto circuit, stopping the spark and shutting down the engine (unlike automotive switches that provide power).
