Embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Utilize the effect of earth gravity and circular motion centripetal force, switch designs become the arc guide rail shape, when the electrical equipment that uses this switch when moving to different angles, switch moves on guide rail, ball is in different determining positions electrical equipment and is in different states.And under action of centrifugal force, the perception of switch is stronger.The utility model switch is in on-state at next path of nature, and another path is in off-state.Two via design to the contact chip of guide rail one side, and are disconnected two paths with the mode of open slot, and public terminal is designed on the contact chip of guide rail opposite side.

As Fig. 1, Fig. 2 and shown in Figure 3, ball switch of the present utility model, contact chip of being installed by both ends of the surface in the band arc-shaped guide rail room 5 and the conduction ball 2 in the room are formed, the both ends of the surface contact chip is connected with room 5 terminal outward, both ends of the surface contact chip on upright position conduction ball 2 and arc-shaped guide rail all bumps and connects, room 5 both ends of the surface middle part is outwards recessed, distance is greater than the diameter of described conduction ball 2 between the room recess, and the contact chip of the end face in the room 5 is connected with room 5 public terminal 4 outward; Open slot 6 is arranged on the contact chip of the other end of room 5, open slot 6 is divided into two parts to contact chip, each several part is connected with room terminal outward respectively, wherein the contact chip as Fig. 2 left side links to each other with the first terminal 1, the first terminal 1 is connected with the circuit of on-state, the contact chip on the right links to each other with second terminal 3, and second terminal 3 is connected with the circuit of on-state.

Between open slot 6 and the vertical line certain angle is arranged, like this, when switch is in normal condition, the contact chip on conduction ball 2 and Fig. 2 left side and the contact chip that is connected public terminal 4 of the other end in the room 5 bump simultaneously and connect, as shown in Figure 4, switch is in erectility, switch energising this moment, electrical equipment operate as normal.As shown in Figure 5, electrical equipment turns over certain angle, the drive switch rotates, but since open slot 6 offer and vertical line between certain angle is arranged, as 10 °, so when having turned to the position as Fig. 5, conduction ball 2 still bumps simultaneously with the contact chip that is connected public terminal 4 of the contact chip on the left side and the other end in the room 5 and connects, switch is in channel status.Turn over certain angle again, as 20 °, as shown in Figure 6, the contact chip on conduction ball 2 and left and right limit and the contact chip that is connected public terminal 4 of the other end in the room 5 bump simultaneously and connect, and are critical switching state.At this moment, also be in "on" position, if Fig. 5 or the "on" position of Fig. 4 are just got back to or got back to switch toward rotating words,, if but when continuing to clockwise rotate, just become the off-state of Fig. 7, conduction ball 2 is not collided with the contact chip on the left side and is connect, and the contact chip that is connected public terminal 4 of the other end in the contact chip on the right and the room 5 bumps simultaneously and connects, at this moment, the switch no power, electrical equipment is in off-position.The contact point 7 that can obviously find out ball switch and guide rail among Fig. 4-7 figure all is the minimum point at guide rail all the time, meets the earth gravity rule.

Room 5 both ends of the surface middle part is outwards recessed, and distance is greater than the diameter of conduction ball 2, like this between the room recess, when electrical equipment was toppled over, when toppling over before and after the switch, 2 contact chips with an end face of conduction ball contacted, as shown in Figure 8, when leaning forward for switch, conduction ball 2 is not collided with public terminal and is connect, switch is in off-state, as shown in Figure 9, switch is toppled over backward, and only colliding with public terminal connects, equally, ball switch also is in closed condition.

Consider from designing, can become sphere shape recess to the room recess arrangement and also can be designed to cylindrical recess that like this, as long as switch one is when being in tilt state, switch cuts off the power supply at once, is active in one's movements, and replys also fast.In order to reduce ball switch in course of action, ball and contact chip are because contact area is little, moment is passed through heavy current, be easy to generate scorification and the situation appearance of blow, can be in design being designed to arc transition between room recess and the guide rail, relative contact is long-pending just big like this, and simultaneously, ball is also relatively milder in rolling process.

Because ball wants power on/off alternately at rolling process, because than the power on/off of heavy current and the situation that produces scorification point exist, so can on the technology contact chip the surface and the conduction ball the surface on be processed into the autogenous grinding surface, just the surface of the surface of contact chip and conduction ball can autogenous grinding, can grind off those fusing points automatically in rolling process.

Simultaneously, can carry out gold-plated processing to contact-making surface for the contact perception on the surface that increases contact chip.

Open slot on the utility model contact chip can be more than one, like this as long as the each several part contact chip that open slot is separated is connected to switch external, multiple connecting line mode just can be arranged, such as the angle that turns over when electrical equipment not for a long time, can increase the circuit connecting mode of power down mode.

The product of present embodiment can be applied to the ball switch that household electrical appliance such as electric iron etc. use, outage automatically under the situation that electric iron is toppled over, and outage is energy-conservation when electric iron inoperative angle, also can be applied to fan etc., topples over easily or rotates in household electrical appliance, toy or the equipment.

The utility model because adopted both ends of the surface contact chip in the room and the conduction ball as switch ways, one end face contact chip connects public terminal, the open slot of contact chip is divided into two parts to contact chip on the other end, connects the room outer open circuit and the terminal that opens circuit respectively.Drive switch when electrical equipment rotates like this and rotate, reach the certain angle outage, can adjust security standpoint by the position angle between open slot and the vertical line is changed.The both ends of the surface middle part is outwards recessed in the room, and distance is greater than the diameter of conduction ball between the room recess, and when electrical equipment was toppled over, the conduction ball only contacted the contact chip of one side, plays power-off protection.Like this simple in structure is active in one's movements simultaneously, and applicability is strong, and excellent product performance, safe is more suitable for the development of modern industry, and low price.
