The gap is needed with the swing bridge to become opened and shut. To attach the conductor rails with each other if the bridge is shut, there is another conductor rail part called "rotary overlap" that is supplied that has a motor. When the bridge is completely shut, the motor of your rotary overlap is operated to turn it from a tilted situation into the horizontal place, connecting the conductor rails for the transition finish area as well as bridge together to supply electricity.[ten]
