Additionally, existing elastic sheet switch internal structure complexity is chaotic, shell fragment easily gets loose and flicks, significantly impact the performance of switch, its susceptiveness is poor simultaneously, it is impossible to reach sensitivity level accurately, it is therefore desirable to design one energising safety, simple in construction and sensitive elastic sheet switch.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of safety that is energized, simple in construction and sensitive elastic sheet switch.
For solving the problems referred to above, the present invention adopts the following technical scheme that
A kind of elastic sheet switch, including switch case and button, one end of described button is connected horizontally on the top in switch case thus the other end of button is in hanging shape, jacking block it is vertically arranged with below button, the fixed block of horizontal expansion is arranged at described jacking block top, and one end of described fixed block and a thin shell fragment is connected；The right side of described switch case is provided with fixing seat, described fixing seat is provided with fixing threaded hole, described fixing seat upper end is provided with normally opened terminals, the lower end of described fixing seat is provided with normally closed terminals, the left side of described normally opened terminals and normally closed terminals is all provided with contact flat spring, the middle part of described fixing seat is provided with energising shell fragment, the left end of described energising shell fragment is provided with copper pearl, the other end tractive of described thin shell fragment is in the end of described energising shell fragment so that the copper pearl on described energising shell fragment contacts with described normally closed terminals；The lower left quarter of described switch case is provided with clamping seat, the rotating shaft being arranged below being fastened in described clamping seat of described jacking block, and on this rotating shaft, cuff has the lower end of spring, the upper end of described spring and described jacking block to offset.
Described elastic sheet switch, it designs further and is in that: described normally opened terminals are upwards bending 30 ° setting.
Described elastic sheet switch, it designs further and is in that: described normally closed terminals are downward bending 30 ° setting.
Described elastic sheet switch, it designs further and is in that: be provided with contact point on described contact flat spring.
Described elastic sheet switch, it designs further and is in that: described keys upwards is provided with felt pad.
Described elastic sheet switch, it designs further and is in that: the bottom of described clamping seat is provided with the clamping mouth relative with described rotating shaft, and described rotating shaft is provided with the projection being held in described clamping mouth.
The invention have the benefit that owing to being provided with switch case, the element of enclosure interior can be wrapped up, prevent electric leakage, owing to being provided with fixing threaded hole, enable to switch case fixed by stud, owing to being provided with normally opened terminals and normally closed terminals, can be energized or power-off, owing to being provided with thin shell fragment, energising shell fragment can be controlled move up and down, owing to being provided with copper pearl, it is possible to be energized with normally opened terminals and normally closed terminal contact, owing to being provided with spring, it is possible to control rotating shaft rotation and fix with clamping seat or unclamp.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of a kind of elastic sheet switch of the present invention.
Fig. 2 is the top view structural representation of a kind of elastic sheet switch of the present invention.
Detailed description of the invention
