The first contact, the second contact are provided with, the first contact is symmetrical arranged with the second contact, and is provided with one end of movable plate and the
The travelling contact that one contact, the second contact are engaged, there is bending supporting part, the other end of movable plate in described third terminal
On be provided with blocked hole, be provided with the snap fit being installed in blocked hole on described bending supporting part, bending supporting part with it is movable
It is provided with reed between piece, to being provided with V-shaped shell fragment at the lower section of inductive switch on described bending supporting part, shell fragment
Upper end is contradicted on the lower surface of movable plate, and the lower end of shell fragment is contradicted on bending supporting part, and the lower end of described switch is supported
Touch on the upper surface of movable plate, switch sub- pressable movable plate and realize travelling contact and the first contact, the second contact and connect
On-off is opened.
The beneficial effect of said structure is：By being provided with spring between the bending supporting part and movable plate of third terminal
Piece, shell fragment, shell fragment can accelerate movable plate to reset, and the travelling contact of movable plate and the first contact, the second contact electric equipment compartment away from
Reach 2mm, improve the electrical safety performance of the microswitch.
Especially, the lower surface of described shell fragment is provided with spacing block set, is provided with and limits on described bending supporting part
The spacing hole that position projection is engaged, described spacing block set are installed in spacing hole and form the clamping of shell fragment and bending supporting part
Coordinate.Shell fragment and the bending supporting part of third terminal are connected by the way of being engaged by clamping, and are easy to the group of shell fragment and third terminal
Dress, and ensure that the connection of shell fragment and bending supporting part is more compact.
Especially, corresponded in described movable plate and hole clipping is provided with reed, one end of described reed is installed on hole clipping
Interior, the other end of reed is installed in the stopper slot on bending supporting part.Reed is installed between bending supporting part and movable plate,
It is easy to the assembling of reed and bending supporting part, movable plate, improves efficiency of assembling.
