The LR09 series Float Switch efficient liquid level detectors are simple to install and designed for trouble free operation over a long life. The LR09 is a plastic float switch using a synthetic rubber 3 core cable. Actuation is via a roller ball and micro-switch arrangement within the switch thereby eliminating all heavy metals from this version. Construction The unit comprises three major components. The float chamber houses the micro-switch arrangement, totally sealed within a polypropylene casing, with a single pole double throw action. The three-cored cable, connected to the micro-switch assembly inside the float chamber, is sheathed in CSP (chlorosulphonated polyethylene) synthetic rubber. This cable is supplied in three standard lengths 1, 5 and 10m ±5% of the length quoted. The optional stabilizing weight may be fixed at any point on the cable using the rubber O-ring supplied.
