Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
As depicted in figs. 1 and 2, a kind of portable sensitive switch in the utility model embodiment, comprise housing 1,1 liang of opposed inner walls of this housing is plugged with the first fixed contact 2 and the second fixed contact 3 being arranged side by side, the first fixed contact 2 contacts with the second moving contact 6 with the first moving contact 5 being arranged on contact bridge 4 respectively with the second fixed contact 3, now, the circuit of switch is switched on.Contact bridge 4 extends upward the guide post 8 that is provided with tooth bar 7 through housing 1 top and edge, contact bridge 4 forms T font with guide post 8, tooth bar 7 is connected with sectional wheel 9, by sectional wheel 9 with the transmission of the guide post 8 of tooth bar 7, drive contact bridge 4 to move up and down, complete and switch on or off this sensitive switch internal circuit, 1 liang of opposed inner walls of housing has chute 18, and the two ends of contact bridge 4 are positioned at chute 18.Preferably, the angle of this sectional wheel 9 is 120 degree, the circle centre position of sectional wheel 9 is hinged on the vertical rod 10 of extending from housing 1 bottom, and vertical rod 10 is through described contact bridge 4, particularly, on contact bridge 4, have pilot hole 16, pilot hole 16 is embedded with fairlead 17, and vertical rod 10 is through fairlead 17, and cover has back-moving spring 11 in the vertical rod 10 between contact bridge 4 and housing 1 bottom, back-moving spring 11 is for externally after steering force disappearance, the contact bridge moving down 4 being resetted, to reclose sensitive switch.
One end of sectional wheel 9 is connected with the joystick 12 that extends housing 1 inwall, by joystick 12 being applied to external force realization, active force is transferred on contact bridge 4 by sectional wheel 8.Particularly, the inwall of housing 1 has breach 13 in the position of joystick 12.The lower end of breach 13 is provided with spring 14, and one end of spring 14 is connected to the lower end of breach 13, and the other end is connected on joystick 12, when spring 14 plays the effect of support, also plays the effect of reset.The upper end of breach 13 is provided with guide vane end stop 15, for limiting the stroke of joystick 12.
