Abstract:
1. An electromagnetic relay comprising: an electromagnet; a movable contact actuated by said electromagnet; a fixed contact disposed opposite to said movable contact and capable of contacting and separating from said movable contact; a backstop for stopping movement of said movable contact in a direction separating from said fixed contact; and a backstop positioner for setting said backstop at a position for defining a predetermined contact gap between said fixed contact and said movable contact, wherein, in a state where movement of said movable contact is stopped by said backstop, different-sized contact gaps are defined between said fixed contact and said movable contact, depending on the position of said backstop set by said backstop positioner, wherein the backstop positioner comprises a first sidewall and a second sidewall, the first and second sidewalls being arranged at opposite sides of a space accommodating the movable contact and the fixed contact so that the movable contact and the fixed contact are disposed between the first and second sidewalls.
