<p>PROBLEM TO BE SOLVED: To provide an electromagnetic relay that is enhanced in reliability of contact connection.SOLUTION: In an electromagnetic relay 1, the circular whole periphery 30a of a fixed constant open contact 30 and the circular whole periphery 40a of a fixed constant close contact 40 are provided to extend over a movable contact 25 on a plane which is substantially perpendicular to the movable direction P of the movable contact 25. In other words, when the electromagnetic relay 1 is viewed from a movable leaf spring 20 side, all of a constant open side movable contact 25a and a constant close side movable contact 25b are located within an area surrounded by the whole periphery 30a of the fixed constant open contact 30 and the whole periphery 40a of the fixed constant close contact 40. A plurality of movable contacts 25 are provided as the movable contacts 25, and the fixed constant open contact 30 and the fixed constant close contact 40 are provided one by one. According to the thus-constructed electromagnetic relay 1, no foreign material infiltrates into the fixed constant open contact 30 side or the fixed constant close contact 40, and the reliability of the contact connection can be enhanced.</p> |
