) The armature (6) is separated from the iron core (8) by a return spring C21) suspended between the central protrusion (9) of the armature (6) and the central protrusion (8) of the armature (6), and is normally closed and movable. The contact (16a) is in pressure contact with the normally closed fixed contact (18a), and the pressure contact is located in the center of the armature (6), so even if the contact position is shifted due to manufacturing errors of each part, In C, the return force of the return spring Ql) suspended in the center is applied to the left and right movable contacts (16→, (
Since it does not act so unevenly between 161 and 161, it is possible to avoid the phenomenon where only one of the movable contacts (16) is worn out, so it is possible to strongly engage the return spring Ql within the normal parts manufacturing error range. Since contact pressure above a predetermined value can be quickly detected in a normally closed contact without having to do so, there is no need to increase the size of the coil or electromagnetic device (4).

Normally open contact pressure can be easily obtained higher than normally closed contact pressure due to Normally open movable contact (16t
) and (t6t), a nearly uniform contact pressure can be obtained, and the normally open type can also be made small and have a high capacity. Of course, in order to make it easier for the armature 16) to tilt, the armature pivot part +7) is placed in the center of the hinge part +7) and +73.
It is also effective to have one small sphere (hexagonal) protruding from the center of 4) and 14) as shown in Figure 2.

Q7) to the metal spring body (15a), (Ll'+b)
The movable contact 06) attached to at least the central metal spring body 05 is used as a sealed contact to contact the normally closed fixed projections Q6a) and Q6a) attached to the base (A). The normally closed side contact, which generally has a lower contact pressure than the normally open side contact, is attached to the metal spring body fIF11) in the center of the armature (6). Therefore, if contact pressure is applied as uniformly as possible to the left and right contacts, then °C1 is a small, high-capacity, multi-pole +1 V-
is obtained. Moreover, since it is attached to a metal spring body 051), it is a Zollinger type contact bounce, which is smaller and has a higher capacity. In addition, in a general hinge type IJ v-, the amount of electricity is limited because the movable contact is led out to the outside of the relay by a flexible lead wire and a conductive metal spring body, but in the present invention, it is led out to the outside by a shorting plate. Therefore, it is possible to achieve high capacity in this respect as well, without the limitations of the conventional method.
