Abstract
The utility model discloses a spinning contact switch. A static contact is arranged in a cavity of a shell. The spinning contact switch is characterized in that a knob provided with a handle is connected in the cavity of the shell through screw thread, the upper end face of the knob is provided with a limiting bar, a guide seat is in sliding fit with the cavity of the shell, a movable contact is arranged on the guide seat, the lower end face of the guide seat is provided with a support spring, and the other end of the support spring is fixedly connected at the bottom surface of the cavity of the shell. The spinning contact switch can avoid the malfunction and has the advantages of high reliability at the same time.
Description
Technical field
The utility model relates to a kind of control switch, particularly a kind of spinning contact-making switch.
Background technology
The existing sensitive switch of individual layer spring leaf that adopts only has one deck operating spring sheet, and its operating principle is as follows; Pushing pin pushing action spring leaf surpasses critical condition, the operating spring sheet produces snap action (wink is moving), the switch motion state is changed, but then can't eliminate the change that the switch motion state that causes is shaken above the operating spring sheet because of ambient vibration or pushing pin pulse promotion generation of critical condition in the end, cause the generation misoperation easily under high vibration and pulse motive force environment of this type of sensitive switch.
Summary of the invention
The purpose of this utility model provides a kind of spinning contact-making switch that can avoid occurring misoperation, simultaneously, the utlity model has the high advantage of reliability.
The technical scheme that realizes the utility model purpose is as follows:
The spinning contact-making switch, be provided with fixed contact in the cavity of housing, one knob that has handle is threadedly connected in the cavity of housing, the turn-knob upper surface is provided with gag lever post, a guide holder is slidingly matched in the cavity of described housing, this guide holder is provided with moving contact, and the lower surface of guide holder is provided with support spring, and the other end of support spring is fixedly connected on the bottom surface of housing cavity.
Described fixed contact and moving contact are the endless metal piece with ball type of contact surface.
Described guide holder is provided with step, is provided with the stopping means of guide holder in the cavity of housing.
Described stopping means is an annular stop plate, on the internal face of this annular stop plate by welding stationary housing cavity.
Adopted such scheme, one knob that has handle is threadedly connected in the cavity of housing, the turn-knob upper surface is provided with gag lever post, distance by the rising of gag lever post restriction turn-knob, when the rotation turn-knob drives rising, when using switch, can reduce the number of times of rotation turn-knob, being beneficial to increases the convenience of using.A guide holder is slidingly matched in the cavity of described housing, this guide holder is provided with moving contact, by the turn knob, can promote guide holder to lower slider, moving contact be contacted with fixed contact, thereby make circuit turn-on, because knob and housing are for being threaded, can prevent to connect circuit, avoid occurring misoperation, to guarantee the reliability of switch by the mode of pushing.The lower surface of guide holder is provided with support spring, and the other end of support spring is fixedly connected on the bottom surface of housing cavity.When needs rotary knob open circuit, be compressed the return action power of formation by support spring, guide holder is upwards slided automatically, thereby make moving contact separate open circuit with fixed contact.
Described fixed contact and moving contact are the endless metal piece with ball type of contact surface.Can increase the contact area of moving contact and fixed contact, guarantee the reliability of switching on.
Described guide holder is provided with step, is provided with the stopping means of guide holder in the cavity of housing.Limit by the step of stopping means guide holder, can limit transition with knob to backspin, cause and damage moving contact and fixed contact.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the structural representation of embodiment of the present utility model;
In the accompanying drawing, 1 is housing, and 2 is fixed contact, and 3 is knob, and 3a is a handle, and 4 is guide holder, and 5 is moving contact, and 6 is support spring, and 7 is stopping means, and 8 is gag lever post.
Embodiment
With reference to Fig. 1, for spinning contact-making switch of the present utility model, be provided with fixed contact 2 in the cavity of housing 1, fixed contact 2 is by on the cavity wall that is fixedly welded on housing, and fixed contact 2 is for having the endless metal piece of ball type of contact surface.One knob 3 that has handle 3a is threadedly connected in the cavity of housing, knob 3 adopts plastic material to make, the turn-knob upper surface is provided with gag lever post 8, a guide holder 4 is slidingly matched in the cavity of described housing 1, this guide holder is provided with moving contact 5, moving contact is the endless metal piece with ball type of contact surface, and the surface area of sound point is less than the surface area of fixed contact.The lower surface of guide holder 4 is provided with support spring 6, and the other end of support spring is fixedly connected on the bottom surface of housing cavity.Guide holder 4 is provided with step 4a, is provided with the stopping means 7 of guide holder in the cavity of housing 1.Stopping means 7 is an annular stop plate, on the internal face of this annular stop plate by welding stationary housing cavity.
