FIELD: electrical engineering; relays, magnetic starters, and switches.
SUBSTANCE: proposed contact is provided with additional working layer, auxiliary layer being disposed between working layers. Working layers are proposed to be made of copper and auxiliary one, of aluminum which will reduce high-cost copper consumption. Working-layer thickness should be minimum 1 mm and thickness of both may be equal. All layers are joined together by explosion welding.
EFFECT: enhanced strength of joint, reduced layer-to-layer resistance, enhanced in-service resistance of layers to separation.
