Abstract
An electromagnetic relay has a mobile contact point attached to a contact member, a fixed contact point, a contact point spring that applies a biasing force on the contact member towards the fixed contact point, a guide that carries the contact member and said contact point spring, a coil that generates a pulling force when excited to move the guide and a returning spring that provides a biasing force for causing the guide to return. A mechanism is provided such that a load is generated on the contact member by the motion of the guide towards the fixed function against the returning spring immediately before the mobile contact point contacts the fixed contact point. This mechanism applies a contact point spring load of the contact point spring and the load as a contact pressure to the contact member for contacting the mobile contact point with the fixed contact point.
