A paste is applied between an inner wall of the receiving groove 31 and a peripheral of the base 1 and between the gap 11 and the convex plate 21 of the pin 2 for fastening.

(12) Besides, another relay device of the present invention may comprise a base 1, a pin 2, and an outer cap 3. The base 1 has a gap 11 arranged at a peripheral thereof. The base 1 is combined with a electromagnet 12 and a control mount 13. The electromagnet 12 has a magnetic end 121 and one end arranged distant from the base 1. The control mount 13 has a covering hole 131 and a control portion 132. The covering hole 131 of the control mount 13 is covered the magnetic end 121. The control portion 132 includes an upper connection sheet 133 and a lower connection pad 134. The lower connection pad 134 is connected to a lower side of the upper connection sheet 133. And the lower connection pad 134 is connected with a second pin 135. The pin 2 has a convex plate 21.
