Simple slack chain switch
The invention discloses a simple slack chain switch. The simple slack chain switch comprises a box; one end of a wear bar penetrates through a sidewall of the box; a spring is arranged between the end, penetrating through the box, of the wear bar and the other sidewall of the box; a lug is formed on the sidewall of the part, located in the box, of the wear bar; a microswitch is fixedly mounted in the box body; the contact of the microswitch props against the lug. In short, due to the adopted technical scheme, the simple slack chain switch is capable of solving the problems of complex structure and low safety of a broken chain detector in the prior art; the microswitch is arranged in the box and triggered by the lug on the wear bar to realize simple slack chain switching operations.
