Side wall on spring face position offer the through slot being packed into for the spring, the length of the through slot is less than the bullet
The length of spring under normal conditions.
In above-mentioned technical proposal, position corresponding with the spring forms the first locating slot on the moving contact, described
The second locating slot is formed in contact mounting groove, the both ends of the spring are respectively at first locating slot and described second and determine
In the slot of position.
In above-mentioned technical proposal, the contact mounting groove is two be set side by side, is divided in two contact mounting grooves
Moving contact described in not being provided with one, two moving contacts are pivotally mounted by pivotal axis described in same root.
In above-mentioned technical proposal, the top of the supporter is integrally formed with upward protrusion, the top end face of the protrusion
There are two colors to indicate area for upper tool, and the color in two color instruction areas is not identical.
The utility model has the effect of positive: moving contact component is structurally reasonable in the utility model, the moving contact group
Part specifically in assembly operation, first welds moving contact and conducting wire, and then the contact by the moving contact mounted in supporter is installed
In slot and pivotal axis is plugged, finally spring attachment positions will be packed by the through slot of side after spring-compressed, thus complete to assemble, by
After first by conducting wire and moving contact welding again by moving contact on the supporter thus when can be to avoid welding lead burn support
The case where part, occurs, and has good using effect.
