ABSTRACT:
An electromagnetic relay is simple in construction, can prevent entry of dust, etc. into an interior thereof, enables confirmation of operation, and is provided an operating lever that can be maintained in an operating state. A coil block and a contact switching mechanism are provided on a base plate, a casing covers the base plate, and a movable iron piece is turned by magnetizing and demagnetizing the coil block, and a movable contact piece is operated to make and break contacts. An operating part that is turned by directing pushing the movable iron piece is arranged on an upper surface of the casing, and covered by a cover. An operating lever is mounted on the cover in a manner to enable sliding operation. The operating lever can be positioned in a closed position, in which an operating part is covered, a first opened position, in which the operating part is exposed, and a second opened position, in which the operating part is operated, respectively.
