Detailed Description
The utility model will be further described with reference to the accompanying drawings in which: as shown in the figure, the temperature control switch comprises a shell 1, wherein a contact piece 4 is arranged outside the shell, a movable contact piece 2 and a static contact piece which are arranged oppositely are arranged in the shell, a connecting piece 5 is arranged on the movable contact piece, a through groove 11 is arranged on the shell, and at least part of the connecting piece penetrates through the through groove and is used for being connected with the contact piece. The utility model provides a temperature control switch, wherein a connecting piece part on a movable contact piece extends out of a shell to be connected with the contact piece, and the cost is low. The movable contact piece and the connecting piece can be arranged integrally or in a split mode.
In the present invention, as shown in the figure, the contact piece is provided with a riveting hole 31, and the connecting piece is provided with a riveting piece 51 opposite to the riveting hole. The riveting sheet penetrates through the riveting hole to realize riveting in a bending mode and the like.
In the present invention, as shown in the drawings, the connecting piece includes a mounting surface 52 on which the rivet piece is provided, and a bottom end surface of the connecting piece is in contact with the mounting surface. In this application, the connection piece bottom is through the riveting of riveting piece directly with the installation face contact, and the bottom of this connection piece of traditional mounting means is the contact of casing outer wall, because the casing is made by plastics etc. mostly, the installation is not firm, and this application is direct metal and metal contact, rivets firmly.
In the present invention, as shown in the figure, the movable contact comprises a bottom sheet 21 and a spring sheet 22, the spring sheet is provided with a contact 221, and the connecting sheet is connected with the bottom sheet.
In the present invention, as shown in the figure, the connecting piece includes a pressing piece 53, the pressing piece is fixedly connected with the inner wall of the housing, and the pressing piece presses the bottom piece against the inner wall of the housing.
