The inductive sensor controls the ignition switch and thus determines the moment of turning off and on the current in the ignition coil. In this way, the inductive sensor also determines the ignition timing.

Since the distributor armature (4) rotates together with the distributor shaft, distance (3) between the distributor armature and the stator poles is constantly changing. As a result, in the magnet winding (2) an alternating voltage is induced. In response to voltage changes, the commutator fires an ignition spark together with the ignition coil. Ignition always occurs when the distributor armature pole moves away from the stator pole again.
In order to protect the switch and the ignition coil from overheating, the switch turns off the voltage to the ignition coil when the ignition is on and the engine is not running.
For safety reasons, the ignition coil has a gap of 5.5 mm from the casing. This is done in order to prevent leakage of the filling mass of the coil in case of defects in the switch of the transistor ignition system.
The main switch board is used for heat dissipation. Before mounting the switch, carefully clean the main board and the attachment point on the body and lubricate with heat-conducting paste to ensure good heat dissipation.
Attention: The heat generated during the operation of the commutator is removed through the body, so while the commutator is not attached, the engine should not be running.
