Отзыв о Универсальность и надежность: получите в свои руки 3-позиционный переключатель VictorsHome LW28-63 с универсальным поворотным кулачковым переключателем и переключателями с фиксацией для высоковольтных приложений! (690В, 63А) от Wayne Laguna

This switch seems to be very well made - with positive clicks in each position and a beefy overall feel to the construction. If you have a basic understanding of electronics, it is easy (via jumpers) to make this a source-selection switch (as I did) for selection between a generator and solar power source. My only negative with this switch - and it is noted when you buy it in the specs and the pictures - is that it is big. Depending on your mounting desire, the sheer size of this switch may be an issue - so keep that in mind.
