GlobalQuestion
When twin contact points and cross-bar twin contact points are compared to a single contact point, what are the characteristics of the former?
Answer
In minimum load applications, contact reliability of twin contact points is higher than that of a single contact point.
Since twin contact points have simply two contact parts, their failure rate related to contact failure is lower than that of a single contact point.
Additionally, cross-bar twin contact points provide further enhanced contact reliability in minimum load applications thanks to their contact form.
However, this theory is not applied for high power load applications, so that a single contact point without AU plating is adopted.

We were using G2R General Purpose Relay to turn a solenoid valve ON and OFF, and sparks at the contact damaged the relay after only about 3 months of use. What caused this, and what kind of countermeasure is there for it?
