Fig. 2 is a structural representation of the present utility model.

Fig. 3 is the structural representation after each parts partition of the utility model.

Embodiment

Below in conjunction with specification drawings and specific embodiments the utility model is described further, but the scope that the utility model is protected is not limited thereto.

As Fig. 1, Fig. 2 and shown in Figure 3:

The ball sensitive switch comprises button 1, loam cake 2, base 3, terminal 4, and button 1 is located in the loam cake 2, and loam cake 2 turns over and is buckled on the

base

3, and 4 of terminals are inserted on the base 3; Also comprise ball 5, ball 5 is located at button 1 bottom, presses button 1 and ball 5 is electrically contacted with terminal 4 or opens circuit.

Terminal 4 comprises conducting portion 41 and pin 42, and conducting portion 41 is located at the top of base 3, the bottom of 42 protuberate basic units 3 of pin.Terminal 4 is two that be arranged in parallel, not conducting mutually, the sphere diameter coupling of the spacing of its conducting portion 41 and ball 5.

Button 1 is provided with the cavity that holds ball 5, and its bottom also is provided with shift fork 11; When pressing button 1, shift fork 11 is stirred ball 5 makes it in the displacement that produces on the slope of boss 31 on vertical and the horizontal direction, the conducting of two terminals 4 of realization or open circuit.Be provided with flexible member 6, flexible member 6 one ends and button 1 butt, the other end and ball 5 butts; Preferable flexible member 6 be the surface through the spring of intensive treatment, be the tower shape, with an end of button 1 butt be carefully to hold, with an end of ball 5 butts be butt end.

Base 3 is provided with a sloping shape boss 31, the shift fork 11 on domatic and the button 1 in opposite directions, 5 on ball is fastened between the two; When button 1 was pressed, shift fork 11 is stirred ball 5 made it in the displacement that produces on the slope of boss 31 on vertical and the horizontal direction, the conducting of two terminals 4 of realization or open circuit.The both sides of base 3 are provided with trip 32, and the both sides of loam cake 2 then are provided with the Access Division 21 that cooperates with trip 32, and loam cake 2 turns over trip 32 flexible being connected on the Access Division 21 when being buckled on the base 3.
