Will coating be generated on the contact surface even in the NC state?
ID： FAQE20024E
update:
Answer
If the contact surface is made of gold or gold alloy, the formation of oxide film is assumed to be less likely.
Explanation
The contact surface used in the NC state will not be corroded when it is not opened and closed, while it may be corroded around the silver contact. If the contact material is gold alloy, film formation is less likely. However, the operating environment may affect the contact surface differently. Please evaluate it based on the environment, actual equipment and actual load before deciding whether to use the switch.
Quick tips
We recommend the sealed basic switch (IP67) with a microload (0.1 A rating: gold contact) as a type with less coating formation.
