Embodiment

Shown in Fig. 1 to 6, a kind of push-button switch, comprise the pedestal 2 that offers groove 1, be arranged on the upper cover plate 3 above the pedestal 2, be arranged on two static contacts 4 of upper cover plate 3 inside bottom, 5, be arranged on upper cover plate 3 bottoms and with one of them static contact 4 corresponding movable contact spring 6, and be arranged on push rod 7 in pedestal 2 grooves 1, the both sides of push rod 7 are respectively arranged with spring 8,9, end one side of push rod 7 is provided with slide bar 10 and offsets with movable contact spring 6, slide bar 10 is telescopic, described another static contact 5 is corresponding with a movable contact group 11, this movable contact group 11 is by the terminal 12 that is arranged on pedestal 2 bottoms, reaching the movable contact spring 15 that is arranged on the terminal 12 by movable contact spring 13 and driver blade 14 forms, movable contact spring 15 is corresponding with static contact 5, and the opposite side of push rod 7 ends is provided with two slopes 16, and this slope 16 is corresponding with the inclined-plane 17 of movable contact spring 15 both sides.

As shown in Figure 4, in the described movable contact group 11, movable contact spring 13 offsets by the aperture 18 of its end and the lug 19 of movable contact spring 15 1 ends, the other end of movable contact spring 13 then offsets by the notch 21 on groove mouth 20 and the terminal 12, the groove mouth 22 of driver blade 14 1 ends by being arranged on its both sides offsets with two groove mouths 23 of movable contact spring 15 other end inboards, and the other end of driver blade 14 offsets by groove mouth 24 and notch 25 on the terminal 12.

Described terminal 12 is by the elliptical aperture 26 of its bottom and the boss 27 corresponding cooperations of upper cover plate 3 bottoms.

When this push-button switch uses, when switch disconnects, promote push rod 7, the scalable slide bar 10 of push rod 7 one side ends just slips on movable contact spring 6, movable contact spring 6 contacts with static contact 4, one side joint of switch is logical, simultaneously, two slopes 16 of push rod 7 end side act on the inclined-plane 17 of movable contact spring 15 both sides simultaneously, and movable contact spring 15 is moved downward, along with push rod 7 constantly moves forward, movable contact spring 15 also constantly moves down, when movable contact spring 15 is crossed dead point between movable contact spring 13 and the driver blade 14, just overturn rapidly, thereby make switch moment realize closed and connect; Otherwise when push rod 7 retreated, movable contact spring 15 moved on will be constantly, and when movable contact spring 15 was crossed dead point between movable contact spring 13 and the driver blade 14, switch will disconnect rapidly, and simultaneously, the movable contact spring 6 of opposite side also separates with static contact 4, thereby switch is disconnected fast.Like this, this push-button switch just can be realized break-make fast in use.
