(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
A kind of sensitive switch, comprise shell 1, be positioned at the installation panel 2 of shell, the moving contact that cooperatively interacts and fixed contact, moving contact and fixed contact are installed in respectively on moving contact installation sheet 3 and the fixed contact installation sheet 4, moving contact installation sheet 3 and fixed contact installation sheet 4 are the strip of vertical layout, on the installation panel 2 that fixed contact installation sheet 4 is installed in groove that the fixed contact installation sheet matches in.Spring leaf 5 its heads that a slice two ends bend in the same way pass through moving contact installation sheet 3, and afterbody is fixed, and the moving contact that this spring leaf 5 is positioned at the moving contact installation sheet is installed a side.The switch knob 8 that sensitive switch push rod 7, head cooperate with sensitive switch push rod 7 also is installed on the installation panel 2, and the afterbody of switch knob 8 cooperates with moving contact installation sheet 3, sensitive switch push rod 7 and switch knob 8 be installed in they adaptive grooves in.
On the installation panel 2 backstay is installed, backstay is positioned at a side of moving contact installation sheet 3, and sensitive switch push rod 7 and switch knob 8 are positioned at the opposite side of moving contact installation sheet 3.Backstay first backstay 9 and second backstay 10 are formed, first backstay 9 is for having the curved bar of two-stage step shape, it is installed in the groove that is mated on the installation panel, the angle of step is towards moving contact installation sheet 3, the afterbody of spring leaf 5 is connected with the trailer card button of first backstay 9, to realize the fixing of spring leaf 5.Second backstay 10 is positioned at first backstay, 9 belows, the head of second backstay 10 is connected with first backstay, 9 buckle-types, the afterbody of second backstay 10 passes through moving contact installation sheet 3, the afterbody of the moving contact installation sheet 3 and second backstay 10 offsets, like this moving contact installation sheet 3 holding position under the cooperatively interacting of the spring leaf 5 and second backstay 10.
