Abstract

The invention relates to a switch contact set mechanism. The switch contact set mechanism comprises a base, a push rod spring base, a push rod spring, a push rod, a movable contact piece support, a static contact set, a binding post set, a first movable contact set, a first movable contact set spring, a second movable contact set and a second movable contact set spring; a first protrusion part anda second protrusion part are arranged on the push rod, the push rod compresses the push rod spring to make the ends of the first protrusion part and the first movable contact set out of contact firstly, and under the effect of the first movable contact set spring, first movable contact points and touch points are in contact breakover firstly; the push rod continues to compress the push rod spring, so that the ends of the second protrusion part and the second movable contact set are then out of touch, and under the effect of the second movable contact set spring, second movable contact pointsand static contact points are then in contact breakover. The contact set mechanism is modularized in integral design, can be assembled with controllable silicon, cooling sheets and circuit boards, andthe efficiency of modularizing and assembling assemblies is higher; the switch contact set mechanism has a strong switching-off function and great shockproof performance, and is compact in structureand wide in using range.

Description

technical field [0001] The invention relates to the field of switches, in particular to a switch contact group mechanism. Background technique [0002] At present, the contact group and the push rod of the speed control switch on the market are installed independently of each other, and the parts are scattered, the structure is complicated, the assembly efficiency is low during the actual assembly process of the switch, and there is a risk that the contact welding post will not be broken. This patent provides a switch contact group mechanism, which can solve the above problems. Contents of the invention [0003] To solve the problems in the prior art, the present invention provides a switch contact group mechanism. [0004] In order to solve the above problems, the solution of the present invention is a switch contact group mechanism, including a base, a push rod spring seat, a push rod spring and a push rod, and an accommodating cavity is opened on the right side of the ...
