The technical scheme adopted by the utility model for solving the technical problem is as follows: the utility model provides a car blet mortise lock slide switch, includes base, slider, reed, switching copper sheet, electric wire, install two switching copper sheets in the base, two switching copper sheets are together fixed with the end of two electric wires respectively, and two electric wires pass the base, and the sliding fit is connected with the slider on the base, and slider and reed fixed connection are in the same place, and the reed is located between slider and the switching copper sheet, is equipped with the several on the reed and is used for contacting the contact of two switching copper sheets.

According to another embodiment of the utility model, the base is further provided with a sliding groove, and the two sides of the sliding block are provided with sliding pieces which are matched with the sliding groove.

According to another embodiment of the present invention, the bottom of the slider is provided with a plurality of slots, the spring plate is fixed with a plurality of protrusions, and the protrusions are inserted into the slots.

According to another embodiment of the utility model, the switching copper sheets are further provided with convex contact surfaces, wherein the length of the convex contact surface of one switching copper sheet is smaller than the stroke length of the contact of the reed.

According to another embodiment of the utility model, the slider is further provided with a second clamping groove.

The utility model has the advantages that the reed is driven by the slider to move linearly, the contact of the reed and the switching copper sheet is realized by the reed moving linearly, so that the conversion of different circuit signals is realized, and whether the safety belt is inserted is judged by a traveling crane computer. The utility model discloses a life and stability have been improved.
