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, the switch of the automatic open and close of a kind of energy in the utility model embodiment, comprises Switch main body 1.1 liang of opposed inner walls of this Switch main body is plugged with the first fixed contact 2 and the second fixed contact 3 that are arranged side by side, the first fixed contact 2 and the second fixed contact 3 match with the first moving contact 5 and the second moving contact 6 that are arranged on contact bridge 4 respectively, particularly, the first moving contact 5 on contact bridge 4, the second moving contact 6 lay respectively at the below of the first fixed contact 2, the second fixed contact 3 and all not contacts, now switch access failure.Contact bridge 4 is upwards extended with the guide post 7 through Switch main body 1 top, guide post 7 mainly plays guiding and the effect of stepping down, guide post 7 has back-moving spring 8 at the bar portion cover that is positioned at Switch main body 1 inside, back-moving spring 8, in compressive state, makes the first moving contact 5, the second moving contact 6 lay respectively at the below of the first fixed contact 2, the second fixed contact 3 but all not contact.Be provided with in the bottom of contact bridge 4 for jack-up the cam 9 that drives contact bridge 4 to move up and down, cam 9 is connected to the drive end of the micro drives body 11 that is positioned at Switch main body 1 bottom by power transmission shaft 10, and preferably, micro drives body 11 is micro motor.Particularly, power transmission shaft 10 is stretched out by the drive end of micro drives body 11 and passes cam 9, and power transmission shaft 10 is supported by two bearings 13 that are arranged on Switch main body 1 bottom.
