■ Forced contact opening mechanism
This mechanism does not operate under normal conditions. However, when the switch plunger overtravels under abnormal conditions the mehcanism comes into operation and forcibily opens the NC contacts thus preventing contact welding.
This action improves the dependability of electrical systems.• The forced contact opening mechanism is provided so as to overcome contact problems.
- Gold-plated contacts and the self cleaning function ensure contact reliability.
- Operational mode indicator can replace existing cover with lamp indicator cover when required.
An LED or neon lamp is used depending on supply voltage. - Contact mechanical design
Contact operating mechanisms can be selected according to the applicationsnap, overlap and normal actions - Conform to IEC Standard
