Furthermore, since the upper end portion and the upper end portion of the armature are connected by a connecting piece made of an insulator, and a fulcrum is provided at the upper end portion of the central piece on the opposite side of the contact,
The pressing force of F is applied to the upper end portion of the movable contact piece by the operation of the armature. In that case, the lower end portion of the central piece of the movable contact piece rotates to the fixed contact piece side with the fulcrum as the center of rotation, and the contact point of the movable contact piece comes into pressure contact with the contact point of the fixed contact piece to establish electrical connection. And when the core loses its magnetism, the Amatyuure desorbs the core. Therefore, the movable contact piece itself is reliably and quickly restored by the elastic action with the fulcrum as the center of rotation. Since such a movable contact piece is operated by the elastic addition action of both side pieces and the center piece, the movable contact piece is formed to be much shorter than the conventional product. It becomes possible to do. Therefore, the height of the electromagnetic relay itself is made lower, which contributes to downsizing.

A magnet (10) having a core (9) is disposed in the center of the. Further, the lower end of the armature (12) is locked to the tip portion of the yoke (11) to which the magnet (10) is fixed, and is opposed to the core (9), and the core (9) is always present. And is urged in the opposite direction. Furthermore, the armature (12) is extended upward (12a) and its extension (12a)

短かく形成することができるのである。Since one embodiment of the present invention has the above-described structure, when the magnet (10) is energized, the core (9) becomes a magnet, and the armature (12) is attracted to the core (9). In that case, as shown by the chain double-dashed line in FIG. 1, the upper end portion of the movable contact piece (2) is pressed by the pressing force of F in the right direction in the figure by the adsorption action of the armature (12). To be done. Therefore, since the lower end portions of both side pieces (2a) (2a) of the movable contact piece (2) are fixed to the bottom plate (1), the movable contact piece (2) follows the pressing force direction of F against its own elasticity. . At this time, since the central piece (2b) is supported by the fulcrum (4) at the upper part of its back surface, the lower end portion thereof rotates to the fixed contact piece (6) side, and both contact points (3) and (5) is attached elastically to make electrical connection. After that, when the energization of the magnet (10) is stopped, the magnetic force of the core (9) disappears, whereby the armature (12) desorbs the core (9) and is separated from the core (9). At this time, also the movable contact piece (2) can surely be restored by the elasticity of both side pieces (2a) (2a) and the center piece (2b) interacting with each other. Therefore, an arc is hardly generated between the contacts, thereby causing neither wear nor welding of the contacts, and with respect to the length l 2 of the conventional movable contact piece (2), the movable contact piece of the present invention ( The length l 1 of 2) can be made extremely short.

ことができる。[Effects of the Invention] As described in detail in the above-mentioned one embodiment, the present invention forms the movable contact piece in a ∃ shape with an elastic body, and fixes the lower end portions of both side pieces, and the upper rear portion of the central piece. Since a fulcrum is provided on the movable contact piece and the upper end portion of the movable contact piece and the upper end portion of the armature are connected by a connecting piece, the action of the armature is transmitted to the movable contact piece to electrically connect and disconnect the fixed contact. The action can be performed reliably and quickly. At this time, since the above-mentioned action is performed by the elastic addition action of both side pieces of the movable contact piece and the central piece, the distance between the fixed contact piece and the movable contact piece can be greatly separated. Since the length of the movable contact piece can be made extremely shorter than that of the conventional product, the height of the electromagnetic relay can be reduced to contribute to downsizing.
