Abstract
A rope tensioner sets the tension of a rope operated switch assembly actuable to switch between first and second conditions on a change in tension of the rope. The tensioner comprises a body, a rotatable member which engages the rope, a shaft for rotating the member relative to the body to adjust tension in the rope by winding the rope around the member, and a lock to lock the member in position relative to the body. The rope opperated switch assembly is much simpler to install than previous assemblies, as the tensioner may be simply threaded or otherwise installed onto the rope without the rope having to be cut.
