With the structure, the first conductive pin can be always in contact with the frame-shaped contact part of the arc-shaped elastic sheet, and the second conductive pin is separated from the second conductive sheet at ordinary times; when the pushing handle is pushed transversely, the arc-shaped elastic sheet is deformed, so that the hook-shaped contact part of the arc-shaped elastic sheet is contacted with the second conducting strip, and the circuit conduction function is achieved.

From the above structural form, it can be known that the present creation has the following advantages:

1. the present creation can prevent the arc-shaped elastic sheet from falling off and shifting due to the long-term repeated deformation by the point friction generated by the flange at the outer end of the frame-shaped contact part on the wall surface of the positioning groove, thereby providing better contact quality and stability.

2. The present creation can only be by the structure locate function of this frame type contact site of the flange reinforcement of this frame type contact site outer end, prevent the deformation damage of frame type contact site, and then extension product life.
