I read in the datasheet of this PCB relay, that the relay has high switching reliability due to crown contacts.
What mean crown contacts ?
1 Answer
It's a characteristic of the forcibly guided relay, see Relay terminology
Crown Contacts: Improved contact form to enforce high contact stress on at least two spots on the contact to penetrate any built-up contamination; to maintain low contact resistance throughout the life of a relay; and to increase the value of switchable output voltage. Supports low current to high power applications.
