Abstract
Official abstract text for this publication.
An electromagnetic relay including an electromagnet, a movable contact actuated by the electromagnet, and a fixed contact disposed opposite to the movable contact and capable of contacting and separating from the movable contact. The electromagnetic relay further includes a backstop for stopping movement of the movable contact in a direction separating from the fixed contact, and a backstop positioner for setting the backstop at a position for defining a predetermined contact gap between the fixed contact and the movable contact. In a state where movement of the movable contact is stopped by the backstop, different-sized contact gaps are defined between the fixed contact and the movable contact, depending on the position of the backstop set by the backstop positioner.
First claim
