Abstract
The utility model discloses a knob switch which comprises a knob subassembly and a knob switch box, wherein the knob subassembly can be rotationally arranged in the knob switch box and contacted with a micro-switch arranged in the knob switch box in a selecting way, the knob subassembly comprises a knob and a cam shaft, the upper part of the cam shaft is fixedly connected with the knob, and the lower part of the cam shaft is provided with an element rest which is contacted with a movable elastic sheet of the micro-switch in a selecting way; a corresponding position of the middle of the cam shaft inside the knob switch box is provided with a positioning elastic sheet, the bottom of the knob switch box is provided with a box cover, a sealing ring is arranged between the box cover and the knob switch box, and the bottom of the inner side of the box cover and a corresponding position of the tail end of the cam shaft are provided with positioning grooves. The knob switch is suitable for high-current switches, has good hand feeling and high safety, and is convenient to use for users.
Description
Technical field
The utility model relates to a kind of electric switch, particularly a kind of rotary switch.
Background technology
Existing high-current switch adopts push-button switch more, and feel is relatively poor during use, and inconvenient user uses, and this type of push-button switch water resistance can't fully guarantee, user's personal safety is affected.
Summary of the invention
For overcoming the defective that push-button switch exists in the above prior art, the utility model provides a kind of rotary switch, and feel is better when both having guaranteed use, the fail safe when having guaranteed again to use.
The utility model rotary switch comprises knob assembly and rotary switch box, and knob assembly is rotatably mounted in the rotary switch box, and touches with the sensitive switch selectivity that is installed in the rotary switch box.
In technique scheme, knob assembly can comprise knob and camshaft, fixedlys connected with described knob in the top of camshaft, and convex tendon is established in the bottom, the removable shell fragment selectivity touching of convex tendon and sensitive switch.
In technique scheme, a shell fragment can be set in corresponding position, rotary switch box inner camshaft middle part; Lid can be established in rotary switch box bottom, between lid and the rotary switch box sealing ring can be installed; Location notch is established in lid inside bottom, the terminal corresponding position of camshaft.
Rotary switch of the present utility model is applicable to high-current switch, and good hand touch is user-friendly to, and fail safe is higher.

Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection range of the present utility model is not subjected to the restriction of embodiment.
Rotary switch of the present utility model comprises knob assembly and rotary switch box 4, and knob assembly is rotatably mounted in the rotary switch box 4, and knob assembly is established two grades of open and close, controls with Location resilient piece 3.Knob assembly comprises knob 2 and camshaft 1, and fixedlying connected with knob 2 in the top of camshaft 1, makes both in aggregates, thereby reaches the effect of transmission.Convex tendon 9 is established in the camshaft bottom, establish sensitive switch 5 in the rotary switch box 4, (promptly when the position of knob in the pass, convex tendon does not contact with the shell fragment of sensitive switch in the removable shell fragment 10 selectivity touching of convex tendon 9 and sensitive switch 5, does not move the sensitive switch contact, does not trigger sensitive switch this moment; When knob during in the position of opening, because the rotation of camshaft, the shell fragment of the convex tendon contact sensitive switch on the camshaft moves the contact of sensitive switch, thereby triggers sensitive switch).
Rotary switch of the present utility model is applicable to high-current switch, and good hand touch is user-friendly to, and fail safe is higher.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection range of the present utility model.
