1). not necessary but is recommended for safety. For GIGAVAC internal armature style relays (GIGAVAC GH1, G8, G61, G50 etc.), the relay base must always be grounded (see Fig. 2) unless the voltage across the contacts is less than the specified dielectric voltage breakdown between the coil and case.

What causes a relay to fail?

In fact, the life of a relay is essentially determined by the life of its contacts. Degradation of contacts is caused from high in-rush currents, high- sustained currents, and from high voltage spikes. … Relays can also fail due to poor contact alignment and open coils.
