Abstract: An electromagnetic relay including a holder capable of not only holding a light-emitting device but also causing a movable core to be moved by manual operation. In the electromagnetic relay, a coil is energized via coil terminals to magnetic and demagnetize a coil block and turn a movable core, thereby moving a movable contact part to open and close a contact. The electromagnetic relay includes a light-emitting device which emits light when the coil terminals are energized, and a holder including a holder body which holds the light-emitting device, an operating portion which moves the movable core by directly pressing the movable core through a depressing operation of the operating portion, and elastic arm portions which connect the holder body and the operating portion and are elastically deformed by the depressing operation of the operating portion.

A coil block and a contact switching mechanism are provided on a base plate, a case is covered over the base plate, the coil block is excited and demagnetized to rotate a movable iron piece, and a movable contact piece is operated via a card, whereby a contact is opened and closed. Bearing portions are formed in the base plate, and an indicator is operated by rotation of the movable iron piece is also provide. The indicator has an elastically deformable structure including pivots which are rotatably supported by the bearing portions of the base plate.

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.

Abstract: An electromagnetic relay having superior visibility and a light-emitting device easy to mount. A coil block and a contact opening and closing mechanism are disposed on a base plate and covered with a case, and the electromagnetic relay magnetizes and demagnetizes the coil block via coil terminals to turn a movable core and moves a movable contact part to open and close a contact. Electrical connection portions of the coil terminals are projected upwardly through the top side of the case. A light-emitting device which emits light by the energization of the coil terminals and a holder which holds the light-emitting device are disposed on the top side of the case on the side opposite to a position where the electrical connection portions of the coil terminals of the case are projected. Lead wires connected to the light-emitting device are electrically connected to the electrical connection portions of the coil terminals.

Abstract: A connector for an electric apparatus has a case and a base which are engaged to each other or integrally formed. The base has an elastic hook and a latch formed integrally on its bottom surface for engaging both edge parts of a rail so as to mount the connector removably to the rail. The case has side surfaces extended from the lower edges to provide extended members for covering both side surfaces of the elastic hook for providing protection against damage when the connector is accidentally dropped. Protrusions may be provided on the bottom surface of the base between the extended members and the elastic hook for limiting twisting deformation of the elastic hook. The bottom surface of the elastic hook has a curved portion for relieving any impact force that may be damaging.

Abstract: A lever with a generally L-shaped main body with a horizontal arm and a vertical arm joining at an angle-forming part is used for removing an electric apparatus from a connector by rotating it around rotary shafts which protrude coaxially from this angle-forming part and are rotatably supported by the connector such that the horizontal part pushes the bottom surface of the apparatus upward and lifts the mounted electric apparatus. A holding structure, which may be in the form of a frame surrounding the electric apparatus to be removed, protrudes from the horizontal arm away from the rotary shaft so as to come into contact with the surface of the electric apparatus away from the vertical arm when the lever main body is rotated by more than a certain specified angle. The electric apparatus is thus prevented from tilting excessively as it is being lifted and hence can be removed without having its terminals bent or damaged.
