Embodiment
In conjunction with the foregoing description accompanying drawing the utility model is described further.
Like Fig. 1-shown in Figure 3:
Described electromagnetic switch of the utility model or A.C. contactor are used latching device; The lock pin 2 and latch hook 5 of mutual correspondence are arranged, and lock pin 2 is arranged on the adhesive armature 1, and latch hook 5 is connected on the snap close base 3 through bearing pin 4 longitudinally; The top connection of latch hook 5 leans out transverse slat 16; Leaning out transverse slat 16 belows has the towed release electromagnet 7 that is fixed on the snap close base 3, and the iron core top of towed release electromagnet 7 is provided with hanging axis 17, leans out transverse slat 16 and is provided with corresponding microscler adjusting lifting hole(eyelet); Hanging axis 17 places microscler adjusting lifting hole(eyelet); The iron core of realizing towed release electromagnet 7 is lifted on and leans out on the transverse slat 16, and towed release electromagnet 7 one sides of latch hook 5 are provided with and lean out arm 6, lean out between arm 6 and the snap close base 3 and are provided with latch hook stage clip 8.Many times snap close base 3 can omit, can be directly with electromagnetic switch base double as.
