The present disclosure relates to the field of material sorting, in particular to a switch
assembly and a sorting
machine, wherein the switch
assembly comprises: a micro switch arranged on a fixed plate, the micro switch comprising a mechanical probe capable of being extended and retracted, the mechanical probe being capable of triggering a corresponding
signal in the extended state and / or the retracted state; a
handle rotatably arranged on a door plate, wherein the door plate is movable relative to the fixed plate; a trigger fixedly arranged on the
handle and capable of rotating synchronously with the
handle, the trigger forming an abutting arc surface; wherein the handle is rotated to a first position, the abutting arc surface pushes the mechanical probe to the retracted state; the handle is rotated to a second position, the abutting arc surface leaves the mechanical probe to extend the mechanical probe to the extended state. The switch
assembly independently forms a chain of the micro switch, the handle and the trigger, and effectively associates the micro switch, the handle and the trigger. The safety and use experience of the whole device are improved, and the reliability and stability of the device are improved.
