Embodiment
Referring to figs. 1 through Fig. 3 the utility model sensitive switch, embodiment is described further.
A kind of sensitive switch, comprise housing 1, actuating mechanism, and part is placed in the button 3 in described housing 1, described actuating mechanism is arranged in housing 1, described actuating mechanism comprises the first terminal 4, the first terminal 5, the 3rd terminal 6 and elastic plate mechanism, described the 3rd terminal 6 comprises the first longitudinal part 61, the first transverse part 62, the second longitudinal part 63 and the second transverse part 64, described the first terminal 4 one sides are provided with the first fixed contact 7, the second fixed contact 8 that described the first terminal 5 one side settings are relative with described the first fixed contact position, on described elastic plate mechanism, be provided with the moving contact 9 that can swing between described the first fixed contact and the second fixed contact, the housing of telling 1 comprises upper cover body body and lower cover, described the first longitudinal part 61 both sides are wider than the first transverse part 62 and the second longitudinal part 63, described the first terminal 4, the first terminal 5, on the 3rd terminal 6 second transverse parts 64, be provided with flower-shaped perforation 4, the first longitudinal part 61 both sides are wider than the first transverse part 62 and the second longitudinal part 63, can guarantee that elastic mechanism is when work, its swinging axle 12 can not be subject to the first transverse part 62 obstruction and cannot be to lower swing.
