Detailed Description

The utility model is described in further detail below with reference to the accompanying drawings:

referring to fig. 1 and 2, a multi-conductive key switch of the present utility model includes a PCB 100 and a key switch assembly disposed on the PCB, the key switch assembly includes a base 200, an upper cover 300, a push handle 400, a spring 500, a movable spring 600 and a static spring 700,

the pressing handle 400 extends downwards to form a guide post 401, and corresponds to a guide hole 202 of a positioning post 201 arranged on the base 200, and the guide post 401 is embedded in the guide hole 202 and can move up and down along the guide hole 202; the PCB board 100 is provided with a light generating tube 101 and a light receiving tube 102, and two opposite light passing holes 203 are formed at one end of the positioning column 201 near the base 200 along the axial direction, and the light passing holes 203 are matched with the light generating tube 101 and the light receiving tube 102;

one side of the push handle 400 is provided with a containing cavity 401, the magnet 401 is arranged in the containing cavity 402, and the magnet 401 is matched with a Hall switch 103 arranged on the PCB 100.

When the utility model works, the push handle 400 is pressed to move downwards, the push handle 400 enables the movable reed 600 to be contacted with the static reed 700, and the key switch is conducted once; in a natural state, the light receiving tube 102 can normally receive the light signal emitted by the light generating tube 101, and the light signal can be preset through a circuit on the PCB board 100, and in this case, the key switch is in an off state; when the push handle 400 continues to move downwards, the push handle 400 drives the guide post 401 to move downwards synchronously until the guide post 401 passes through the light holes 203, and the light passage between the light generating tube 101 and the light receiving tube 102 is blocked, so that the light receiving tube 102 cannot receive the light signal emitted by the light generating tube 101, namely, a signal with blocked light passage is generated, and the key switch is conducted for the second time; when the push handle 400 continues to move downwards, in a natural state, the magnet 800 on the push handle 400 is far enough away from the Hall switch 103 on the PCB 100, the Hall switch 100 on the PCB 100 cannot sense the magnetism of the magnet 800, and a circuit is disconnected, namely, the key switch is in a disconnected state; when the push handle 400 continues to move downwards, the push handle 400 drives the magnet to move downwards, and when the push handle 400 is pressed downwards to a certain stroke, the magnet 800 is close to the Hall switch 800 on the PCB 7, the Hall switch 800 senses magnetism, and the circuit is conducted, namely the key switch is conducted for three times.
