Relay Contact Resistance at Sanford Lilley blog

Relay Contact Resistance. An ideal relay contact would consist of highly conductive metal with chemically clean surfaces (no oxidation) and a large, wear resistant, effective contact area. Open contacts would ideally have infinite dielectric strength for electrical isolation. Elevated resistance not only amplifies the power dissipated within the relay but also increases heat generation. The contact resistance is a combination of the inherent resistance of the conductors that make up the armature, terminals, contacts, and other parts, the boundary resistance where the. When current flows through relay contacts, it encounters resistance, a factor contingent on the size and material composition of the contacts. When the contacts close the equipment measures the voltage drop at 10 ma, but the 1 v open circuit voltage also effects relay switching performance. Initial contact resistance is the resistance of the contact when the relay is new. As the relay ages, switching significant current, the contact resistance can be expected to. The primary reason that almost all relays have a minimum load requirement is that the mechanical action of closing coupled with.
