Embodiment
Referring to figs. 1 through Fig. 3, the straight key mains switch of the utility model embodiment is described further.
A kind of straight key mains switch, comprise push shaft 1, spring 2, pedestal 9 and upper cover 10, in described pedestal 9, include slide block 3, touch device and static palping foot, on described pedestal, be provided with square groove, chute and screens projection 13, described touch device and static palping foot are arranged on square groove, described screens projection 13 is arranged on chute bottom, described slide block 3 is arranged on chute, described touch device includes movable contact plate 5, moving contact shell fragment 8, moving contact rack 4 and moving contact, described movable contact plate two ends are provided with 5.3 first through holes and 5.4 first through holes, described through hole is for fixing moving contact, described moving contact is divided into the first moving contact 6 and the second moving contact 6.1, described static palping foot is divided into the first static palping foot 7 and the second static palping foot 7.1, described moving contact shell fragment 8 and 5 clampings of movable contact plate, described moving contact rack 4 and static palping foot are set on pedestal, described moving contact rack 4 is provided with the gauge mechanism for blocking movable contact plate, described movable contact plate 5 is provided with the position-limit mechanism that restriction movable contact plate moves left and right, described gauge mechanism and position-limit mechanism clamping.
Moving described gauge mechanism includes and puts groove 4.1 and latch 4.2, described latch 4.2 is arranged on and puts groove 4.1 notches, described latch 4.2 directions are in putting geosynclinal concave groove 4.1, described latch 4.2 is rendered as antiparallelogram by the cross section of one end, the cross section of the other end is rendered as right-angled trapezium, while making to assemble, can easily moving contact be packed into and put in groove 4.1, can effectively fasten movable contact plate 5, prevent that movable contact plate 5 from skew occurring and cause moving contact to contact with static palping foot 7.
Described position-limit mechanism includes the first spacing block set 5.1 and the second spacing block set 5.2 forms, described the first spacing block set 5.1 and the second spacing block set 5.2 are arranged on the both sides of touching plate 5 middle parts, the distance of described the first spacing block set 5.1 and the second spacing block set 5.2 is than the large 4mm of latch thickness, and such setting is in order to provide movable contact plate the space that can swing.
Specific implementation process: in the time that actuating mechanism is installed, latch is aimed between the first spacing block set 5.1 and the second spacing block set 5.2, firmly movable contact plate 5 is pushed into and is put in groove, now latch 4.2 is between the first spacing block set 5.1 and the second spacing block set 5.2, and shake-up plate 4 is engaged in and is put in groove, movable contact plate 5 can not dropped out in gauge mechanism, again because latch 4.2 between the first spacing block set 5.1 and the second spacing block set 5.2, movable contact plate 5 is stung the effect of tooth 4.2 and position-limit mechanism and cannot be moved left and right.
