Description

Detection switch

Technical Field

The utility model relates to an electronic components field of control circuit switching, concretely relates to detection switch.

Background

The detection switch mostly adopts a handle for shifting or vertically pressing the switch to drive pins in the handle to be connected into different loops to realize the detection of shifting and pressing directions and/or strokes. For example, a two-contact detection switch often needs to control current to flow through different circuits when the handle is moved left or right to detect the motion.

For example, in the detection switch structure disclosed in the chinese patent application No. 201710679920.4 previously applied by the present applicant, the torsion spring and the torsion spring pin attached thereto are used as the conductive control component, but the processing accuracy of the torsion spring is low, and the torsion spring is difficult to position during assembly due to the processing accuracy of the torsion spring, and can be assembled only in a manner that the movement space of each component is limited by the cooperation of the components, and a large space needs to be reserved, so that zero configuration is difficult to realize, which also results in high switch design difficulty, low assembly yield, and high failure rate.

For example, the lever-operated switch disclosed in chinese patent publication No. CN1256742C drives a plate-shaped sliding member engaged with the lever (i.e., a handle) through a pivoted lever, and then drives a movable contact member (i.e., a spring plate) through the sliding member, thereby forming a structure in which the spring plate is indirectly driven by the handle. In the structure, the manufacturing of the sliding part, the assembly of the sliding part into the switch and the like bring about the increase of cost, an assembly gap is arranged between the lever and the sliding part, and an assembly gap is arranged between the sliding part and the movable contact part, namely, the increase of the overall assembly gap in the switch is brought about due to the arrangement of the sliding part, so that the lever is often required to deflect more than 20 degrees to control the current to flow through different circuits, namely, the detection precision is limited. And because a sliding part driven by meshing is added, in the application of the micro switch, higher requirements are put forward on the manufacturing precision of a lever, the sliding part and a movable contact part related in the switch, and the problem of low product yield is caused because the assembly clearance is easily expanded due to too low precision.
