Description
Technical field
The utility model is related to it is a kind of realize electromagnetic shielding and hermetically sealed function button switch.
Background technology
Button switch is by driving the switch that inner contact is changed with the collinear motive force of button stroke.It is each
Quasi-instrument, instrument, electromechanical equipment console and panel control system in critical elements；It is characterized in that being arranged on work is carried out
In machine, in instrument, the most of the time is on the position of initial free state, and is only transformed into the presence of external force
Two kinds of states (position), when external force once removing, due to the effect of spring, switch is returned to initial position.
If conventional seals button switch is under panel in moist or serious dust environment in use, easily make out
Portion's ponding or dust stratification cause loose contact inside the Pass, so as to cause switch failure.
Utility model content
In order to solve the above technical problems, the utility model provide it is a kind of realize electromagnetic shielding and hermetically sealed function button
The button switch of switch, realization electromagnetic shielding and hermetically sealed function can be realized effectively by improving switch-mode metal shell mechanism
It is hermetically sealed, it is ensured that to ensure the reliability of normal work under dust and moist adverse circumstances.
The utility model is achieved by the following technical programs.
It is provided by the utility model it is a kind of realize electromagnetic shielding and hermetically sealed function button switch, including shell, handle,
Stage clip, pedestal, microswitch unit, button riveting；Described handle can move up and down, and handle is internally provided with stage clip and two steel
Ball, handle outside are provided with stage clip, the extension knot that handle bottom extended structure is fixed in stage clip upper end, lower end is fixed in shell
Structure, handle low side, which is fixed with, cuts somebody's hair；Shell bottom is sealed by button riveting, and shell inner bottom part is fixed with pedestal, is fixed with pedestal micro-
Dynamic switch element；The handle is cut somebody's hair in extreme lower position and presses microswitch unit, and handle is at extreme higher position, at stage clip
In free state, and handle top flushes with housing top end.
The handle is internally provided with steel ball, and steel ball number is two, and is fixed with spring between two steel balls.
The microswitch element number is more than one.
Inner waterproofing circle is provided between the side wall and handle of the shell.
Outer water proof ring is fixed with the outside of the shell side wall tip position.
The microswitch unit is fixed by the alignment pin of bottom.
The beneficial effects of the utility model are：By improving switch-mode metal shell mechanism, can effectively realize it is hermetically sealed, really
Protect under dust and moist adverse circumstances and ensure the reliability of normal work.
