## **- TRITON CONTROLS FLOAT SWITCHES** , **–** ~~a~~ **LR08, LRW8 NON MERCURY LEVEL** ~~e~~ **REGULATORS**
Float Switches are inexpensive and efficient liquid level detectors. They are simple to install, and designed for trouble free operation over a long life. The LR08 is a plastic float switch using either a PVC or 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:
1. The float chamber houses the micro-switch arrangement, totally sealed within a polypropylene casing, with a single pole double throw action.

2. The three-cored cable, connected to the micro-switch assembly inside the float chamber, is sheathed in CPE (chlorinated polyethylene) synthetic rubber or PVC. This cable is supplied in three standard lengths, 5 metres, 10 metres and 20 metres ±5% of the length quoted.
## 3. Two versions are available: **LR08, LRW8**
- a. **LR08** The float is a standard buoyant type and an optional stabilizing weight may be fixed at any point on the cable.
- b. **LRW8** Where the counter weight is inside the polypropylene chamber, hence giving the float a self tilting action.
## **Mounting**
Whilst no hard and fast rules apply to the mounting of these units, the lead should be supported in an enclosed vessel, and in an open vessel it is advantageous to clip the lead to the side, especially if excessive turbulence is experienced.
To obviate the effects of rapid switching conditions that would result if such turbulence is experienced, it is advantageous to use a maintaining circuit which both safeguards the micro-switch and cuts out any chatter in the starters of associated pumps etc
Contact rating: 250V 15A, non-inductive. 250V 10A, inductive. 1.3 HP
## **LR08 - NON MERCURY FLOAT SWITCH Method of Operation**
The micro-switch assembly inside the float, axially mounted in line with the weight, changes contacts according to the float’s position, as in the diagram below. Therefore as the liquid level drops or rises slowly, a pump or flow control suitably connected, can be switched in or out to maintain an average level of the liquid. By connecting only one side of the switch, the unit can be also used to fill or empty the tank as required.
**NOTE :** Local regulations may limit the voltage.
