Description
Technical field
The utility model relates to the improvement of push-button switch structure.
Background technology
Refer to and utilize button to promote transmission mechanism, moving contact and fixed contact are opened by on-off and the switch of realizing circuit changing-over.Push-button switch is that a kind of structure is simple, application master control electrical apparatus very widely.In electric automatic control circuit, for manually sending control signal with control contactor, relay, electromagnetic starter etc.Current button is based on spring button, and spring button long rear spring service time can be aging, button cannot be upspring, affect the effect of push-button switch.In addition, existing push-button switch easily occurs careless by mistake by the problem of switch.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of long service life and not easily occurs missing a kind of magnet button pressing switch problem.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises housing, it is characterized in that: housing upper center is provided with spacing hole, the connecting rod of described spacing hole is provided through in spacing hole, outside, connecting rod upper end are provided with pressing plate, housing inside connecting rod lower end is provided with conductor contact plate, conductor contact plate upper end is provided with magnetic block; Be provided with two hard contacts in enclosure interior bottom, enclosure interior upper end is provided with magnet; Enclosure interior bottom is provided with the spring corresponding to contact plate; Outside is provided with extension plate, extension plate is provided with bull stick, described bull stick is connected with extension plate by bearing, and bull stick upper end is provided with shutter, and described shutter is arranged on above housing.
As a kind of preferred version, described housing is plastic casing; Plastic casing is sturdy and durable and cheap.
As another kind of preferred version, shutter upper end is provided with fluorescence coating; Arranging fluorescence coating can in the position of indication button switch at night.
The utility model beneficial effect:
The utility model not only has spring reset function, and contact plate is also by upwards resetting under the magnetic block of setting on it and the magnet adelphotaxy of housing upper end.Play the effect of dual fail-safe, even if spring is aging under long-time use, also by resetting under magnetic block and magnet effect.Therefore long service life.In addition, the utility model can use shutter to shelter from pressing plate, avoids occurring accidentally dropping by mistake by the problem of switch.Need by rotating bull stick, shutter to be removed during pressing pressing plate.
Accompanying drawing explanation
The technical problem solved to make the utility model, technical scheme and beneficial effect are clearly understood, below in conjunction with the drawings and the specific embodiments, are further elaborated to the utility model.Should be appreciated that embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
