There is provided on the top surface of relay body and integrally formed therewith, electronic unit connection terminal 3 is from the bottom surface of relay body
Prominent, connector 901 includes a terminal, and terminal and electronic unit connection terminal 3 are connected to and be arranged in relay body
Fixing terminal 9.Electronic unit connection terminal 3 and fixing terminal can be constructed by same component or separate member.Electronic unit connects
It is connected to electronic unit connection terminal 3.
The sectional view of electromagnetic relay shown in Fig. 1, including substrate 1, be set up in parallel on the substrate 1 electromagnet unit 2,
Plate 8, removable terminal 5 and fixing terminal 9；Electromagnet unit 2 includes yoke 201 and is fixed to the coil 202 of yoke 201；
One armature 4, inside sets a rotary shaft, is rotatably affixed to by rotary shaft 6 in yoke 201, and the two ends of the rotary shaft 6 are fixed to
(not shown) on the side wall of relay body, positions armature using fixed rotary shaft；The armature 4 is bent to substantially
The shape of broken line, the upper end-face edge of the yoke 201 of electromagnet unit 2, which closes on, fixes a hinge spring at armature supporting point position
(not shown), hinge spring can provide a power-assisted when electromagnet unit is not powered on so that armature upper end is reset to correctly
Position.Plate 8 is swingable to be fixed on substrate 1 so that plate 8 can be put to the direction of armature 4 or removable terminal 5
Dynamic, the plate 8 includes the first termination 801 and the second termination 802, and the first termination is contacted with armature 4, and the second termination is with may move
