What is the difference between single contact, twin contacts and crossbar twin contacts in the contact mechanism for relays?

The following table shows typical contacts of our relays.

• We have a double (or twin) break contacts type relay in our single contact relays. Double break contacts are suitable for opening and closing large-capacity loads that require breaking capability due to the large gap between the same polarity contacts.
• Crossbar single contact has the advantage of providing good contact matching even with slight contact misalignment, and is used for relatively small current capacities.
• The crossbar twin contacts have two contact points and have the advantage of a crossbar shape, making it suitable for opening and closing microloads.
