Description
Technical field
This utility model relates to a kind of switch, especially a kind of press button for cleaning machine。
Background technology
Press button is the switch by pushing a button to realize switch on and off, generally include two static contacts and a moving contact being connected with button, moving contact is connected across between two static contacts, realizes switching on-off by moving up and down of button control moving contact。This press button, with two contact, causes that the resistance of switch is big, and can produce electric arc when switching off between contact and easily burn out contact, and multiconductor improves the fault rate of press button, reduces service life。
Summary of the invention
For above-mentioned reasons, the purpose of this utility model is in that to provide a kind of simple in construction, the press button that contact is few。
For achieving the above object, this utility model adopts a kind of press button, including shell, pedestal, button, slide block, moving contact, static contact, two buttons are arranged on shell, moving contact and static contact are arranged in pedestal, casing cover is on pedestal, slide block is arranged on the moving contact in pedestal, two buttons are connected with slide block two ends respectively, described moving contact is arc, moving contact top correspondence static contact arranges movable contact, in the middle part of moving contact, both sides outwardly convex forms side plate, moving contact rack it is provided with in pedestal, two side plates of moving contact rack one end correspondence moving contact form two side plate grooves, the bottom centre of side plate groove is upwardly, moving contact is connected on moving contact rack by side plate and the spacing of side plate groove, slide block withstands on the swing of sliding control moving contact on the moving contact of arc。
This utility model is further arranged to described its center and is hinged on shell, slide block lower end arranges pellet, pellet withstands on moving contact, slide block both sides form joint face upward, two joint faces are formed the connecting hole of cambered surface depression, two buttons extend to form button connecting rod in shell, and button connecting rod withstands in the connecting hole of slide block。Slide block is hinged on shell and controls vacillating now to the left, now to the right of slide block by two buttons, and compact conformation is easy to assembly。
This utility model is further arranged to the bottom of described side plate groove and forms downward-sloping two inclined-plane from prominence, center to both sides respectively。Can fit when moving contact is rocked to the end and play a supporting role in inclined-plane, it is prevented that moving contact deforms。
This utility model is further arranged to described its center and forms jointed shaft, and the two ends first half of jointed shaft is inclined-plane, and shell is formed hinge hole, and jointed shaft snaps in hinge hole hinged by inclined-plane。Inclined-plane on jointed shaft snaps in the easy to assembly of hinge hole。
This utility model is further arranged to the tail end downward bending of described moving contact and forms barrier sheet。Barrier sheet can withstand on moving contact rack when moving contact disconnects, it is prevented that moving contact transition swings and deforms。
It is the inclined-plane to contract that this utility model is further arranged to the sidewall lower semisection of described side plate groove。Inclined-plane can facilitate the side plate of moving contact to be installed in side plate groove。
The beneficial effects of the utility model are to adopt the moving contact of arc, being moved at moving contact by button control slide block allows moving contact wave, so that the moving contact on moving contact top has certain stroke and realizes the disconnection with static contact or Guan Bi, contact between this moving contact and static contact is few, save the cost of contact, reduce because of the resistance of multiple contact, and breaking speed is fast。
