Abstract:
1. A micro switch, comprising: a bracket; at least one conductive terminal assembly substantially disposed in the bracket and having a first terminal, a conductive plate, a spring and a second terminal, one end of the spring being hooked on the first terminal, and the other end thereof being hooked on the conductive plate, one side end of the conductive plate being pivotally engaged to the first terminal; a push rod slidably disposed in the bracket substantially and straddled by the at least one conductive terminal assembly, the push rod having a recess and a top flat portion next to the recess on a side surface thereof, wherein a side wall of the recess adjacent to the top flat portion is formed as a inclined surface; and an electro-magnet disposed in the bracket next to the at least one conductive terminal assembly and having a coil and an armature, wherein one end of the armature is connected to one end of the push rod; wherein when being positioned in the recess, the spring is in an unforced state, so as to disconnect the conductive plate from the second terminal; alternatively, the push rod is pushed toward the electro-magnet to make the spring slide along the inclined surface to the top flat portion, and the spring is abutted against the top flat portion to deform, so as to make the conductive plate rotate toward and in contact with the second terminal.
