いう効果がある。As described above, according to the electromagnetic relay of the present invention, the provisional fixed terminal is provided at the tip of the fixed terminal, and the fixed terminal is bent and implanted in the insulator base, so that the tip and the root of the fixed terminal are fixed. Since the fixed terminal can be fixed by the insulator base, the fixed terminal does not rise when the external lead-out terminal is bent, so that there is an effect that the characteristics of the relay can be stabilized. Further, since the present invention enlarges the fixed terminal itself, the present invention has an excellent effect of dissipating heat generated when switching large currents, preventing welding due to transfer of contact metal and the like, and extending the life. .
