Abstract
The utility model discloses a displacement stroke switch. The displacement stroke switch comprises a housing, a light beam channel is arranged in the housing, a light beam collector is arranged in the light beam channel, a displacement stroke channel is arranged in the housing, a reflector is arranged at the connecting position of the displacement stroke channel and the light beam channel, a fiber transmission channel is arranged in the housing, a light beam inductor is arranged between the fiber transmission channel and the light beam channel, a photoelectric signal converter is connected with the light beam inductor, a fiber checking device is connected with the photoelectric signal converter, a transmission fiber is connected with the fiber checking device, and a sealing inner film is arranged in the light beam channel. The displacement stroke switch is simple in structure and convenient and rapid in use; displacement can be converted into a light velocity, the light velocity is converted into a fiber transmission signal, and the fiber transmission signal is then transmitted; electrical signals are not directly generated in the displacement stroke channel; and the displacement stroke switch can be widely applied to high-voltage or inflammable places, and the using stability, safety and practicality are high.
