The working principle of the single electrode solid warp stop motions

When using a single electrode solid warp stop motions, 

the motions are fixed to the bracket, and a warp stop 

plate must be installed underneath the motions, which 

is covered with a thin metal plate, which is connected 

to the warp stop conductor. When the warp stop sheet

do not touch the warp stop motions, the loom operates 

normally. When the warp breaks, the drop wire falls 

down and contacts the drop wire plate, causing the warp 

stop circuit to conduct and the weaving machine to stop.
