Twin contacts. Divide and rule

Would you able to differentiate a twin contact at first glance?

It´s easy to appreciate how in a twin or bifurcated contact, all their blades are divided into two parts, each one with their own contact.

Each of this twin contacts press simultaneously on the independent fixed connections of the relay. And this coordinated effort is most useful when you want to switch low loads with very high reliability.

When should you use a twin contact?

Four of our families (RM, RQ, RF and RR) offer the possibility of including twin contacts, and they are considered the most suitable at the time of switching very low signals -from 1mA @ 5V to 5A-; because they achieved a mean time between failures (MTBF) that optimizes the switching reliability.

All of these features shape the suitable relay in cases where the intallations have such a small signal (below 50 mA) that make a common relay does not work properly. For example, an interface relay for a frequency inverter or an input signal to a PLC.
