Switching device

A switching device, comprising:

• an electricity leading member, wherein a first end of the electricity leading member is configured to be electrically connected with a power supply terminal, and a second end of the electricity leading member is provided with a first contact portion;
• a power transmission member, provided with a second contact portion, wherein the second contact portion is configured to be electrically connected with the first contact portion in a contact manner;
• and
• a conductive connecting member, wherein the conductive connecting member has one end connected with the electricity leading member, and another end connected with the power transmission member, and the electricity leading member is electrically connected with the power transmission member through the conductive connecting member,
• wherein the conductive connecting member is made of an elastic metal, and comprises a connecting body and a plurality of clamping bodies, wherein the connecting body is connected to the electricity leading member, and one end of each of the clamping bodies is connected with the connecting body, and the plurality of clamping bodies form a clamping space for clamping the power transmission member,
• each of the clamping bodies is an elastic member;
• each of the clamping bodies has an inner side surface for abutting the power transmission member, and the inner side surface of each of the clamping bodies is bent inward, so that the inner side surface forms a convex curved surface;
• an opening formed by ends of the clamping bodies adjacent to the connecting body is larger than an opening formed by middle points of the clamping bodies, and an opening formed by ends of the clamping bodies away from the connecting body is larger than an opening formed by middle points of two clamping bodies.
