Hi all...a little off topic but...i'm looking for a cable pull (or sometimes called rope pull) switch, used for the opening and closing of a cooler door by forklift operators. the box mounts to the celing and has a spring and a micro switch. when the rope is pulled the micro switch closes momentarily and the door opens. i have been all over the internet and cant find one. the old one is damaged beond repare and has no nameplate. please help. thanks
