A mechanically actuated sensor indicates the position of a piston within the cylinder of a piston and cylinder assembly. The sensor includes a cam that partially extends into the cylinder chamber for abutting contact with the piston, and a lever arm extending through the cylinder wall for transmitting movement of the cam to a signalling device mounted externally of the cylinder chamber.
