Interrupter already after the first use. In the previous factory deep burnout so went to replace with this one. I installed, adjusted the gap , took to setting the ignition point on the "beeper" into the multimeter and silence. I shorted the contacts and still silence. I cleaned the contacts with dry paper , silence. With damp, no conductivity. I washed with nitro, does not conduct. I wiped with sandpaper 2500 dry and wet, does not conduct. Then 1500 and finally 800, it began to conduct. That is, there were non-conductive oxides on the contact surface. Unfortunately, the sandpaper made scratches. Delicate but nevertheless and the current will already gush and burn there. Contact adhesion with a slight clearance in the plane perpendicular to the axis of rotation. I corrected by bending with pliers. In the other plane OK. The contacts overlap the entire surface. Hammer with a high projection. The screw for attaching the cable works. It has an additional copper strip under the spring, improving conductivity. Goods comparable to the original although Made in China product. Trouble-free for the ignition drove the first 200km. What kind of service life it will come out after tens of thousands of km, but about that I will not write here anymore.

Reliable opinion
