The central portion of the elastic piece 4 is separated from the positive electrode 21, and when the shaft cylinder 3 is driven by an external force via the button 70, the elastic piece 4 can be pushed. The central portion of the crucible contacts the positive electrode 21' to cause the elastic piece 40 to be connected to the positive and negative electrodes 21, 22, and the central portion of the elastic piece 40 is elastically reset after the force is released from the drive shaft barrel 30, and is separated from the positive and negative electrodes 21, 22. ^ The bottom of the button 70 forms a recess 73 corresponding to the receiving groove 11, and the axial end is embedded in the recess 73. _ In addition, since the button 70 made of silicone has a high temperature resistance, the button 70 can enter the tin furnace along with the shaft 3〇 and the base 1 without having to be switched as in the conventional manner. After the susceptor has passed the tin furnace, the button is mounted on the shaft to further save the process. Furthermore, the button 70 is flexible and elastic, and can effectively relieve the collision force to increase the durability of the switch to accept the endurance.
