Switching system
Is equipped with double-break jump contacts. Owing to the large
cleaning path, outstanding self-cleaning is possible. The multilayer
contacts are designed for universal use. They are gilded with a 2 μm
gold coating. Each snap-action switching element comprises a NC
(normally closed contact) and a NO (normally open contact).

Switching system
Is equipped with rigid contact link. The slow-make element opens
positively and simply consists of a double-break NC. The multilayer
contacts are designed for universal use and are gilded with a 2 μm
gold coating. The Stop slow-make element is designed according
to EN IEC 60947-5-1.
