Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in further detail.
Embodiment as Figure 1-3, the microswitch includes shell body 1, inner housing 6, and first end subgroup 2, presses
Button drive mechanism, shell fragment drive mechanism, Second terminal group 5.
Shell fragment drive mechanism 4, Second terminal group and inner housing 6 constitute a sub- microswitch, be equipped with housing 6 son by
Button 7.Second terminal group is made up of the terminal 21 and terminal 22 being set up in parallel, and two-terminal is installed in pedestal 9, and the top of terminal 21 sets
Bifurcated is put, the upper end of terminal 22 to the direction of shell fragment 41 bending is located at the top of shell fragment 41.Shell fragment 41 is horizontally installed on terminal 21, one end
And middle part is socketed in respectively on two bifurcateds on the top of terminal 21, the other end is provided with contact.First end subgroup is by terminal 51
Constitute with terminal 52, terminal 51 and the one end of terminal 52 rivet respectively or be welded on the termination of terminal 21 and terminal 22, the other end is stretched
Go out outside housing 1.
Wherein, button drive mechanism includes the first button 31, first be limited between the first button bottom and shell body
Spring 32, the first button is made up of top, bottom, and second spring 33 is provided between two parts, and the first button bottom has one
The press section 310 of horizontally set, the press section is located at sub- button top.The bottom of sub- button 7 props up shell fragment 41.
During work, the first button 31 is pressed, and then press section 310 pushes sub- button 7, sub- button oppresses the one end of shell fragment 41,
The other end of shell fragment 41 is upspring, and contact contacts with terminal 22, connects terminal 21 and terminal 22, then terminal 51 is also connected with terminal 52,
Realize the UNICOM of external circuit.
In the present embodiment, button drive mechanism is provided with two section back-moving springs, then button as the first pressing transmission again
It is longer that stroke is set, pressing feel is strong, two section springs can preferably buffer damage of the improper operation to switching, and reset reliable；And
First Long travel for pressing again arranges the requirement on machining accuracy that can suitably reduce the second weight pressing component, and then reduces cost.
In practical application, inner housing 6 can be made into waterproof case, and seal member 8 is socketed with outside sub- button 7, by sub- button
Gap sealing between inner housing.Or, seal member makes integral with inner housing 6, is made using water-proof silica-gel.
In practical application, sub- button 7 can be omitted, and the first button is set directly at into the top of shell fragment 41, be reserved on housing 6
For the hole that the first button 31 is penetrated, in hole, periphery set sealing shroud does water-proofing treatment etc..In view of pressing buffering and pressing stroke, the
One button is divided into two parts, and centre is also provided with spring, and the spring can also be omitted.In addition pedestal 9 also can be omitted, by each part
It is directly installed in waterproof case 6, corresponding position limiting structure only need to be set in waterproof case 6.
In this embodiment, the connected mode that terminal group is arranged is normally opened, i.e., when not working, the electric state of two-terminal is disconnected
Open, when pressing shift knob work, the electric state of two-terminal is connection.During concrete setting, normally closed switch is may be alternatively provided as, pressed
When lower shift knob works, terminal disconnects, and only need to do minor adjustment in switch internal structure.For example, during original state
Make the press section of button 31 oppress sub- button 7 by the setting of spring, when pressing shift knob 31, make press section depart from sub- button
7, realize disconnecting；Or during original state, by the adjustment of terminal 22, make shell fragment 41 first contact bending in lower section terminal 22, press
During lower shift knob 31, make press section press sub- button 7, realize disconnecting.These adjustment all should be within the scope of the present invention.
