Gentech Float switches

GENTECH FLOAT SWITCHES contain a reed switch with an actuator magnet in the float. Material is glass filled polypropylene or nylon 6.6 moulding. (See temperature rating). Contacts close when the magnet assembly reaches the centre line of the main body. Normally open or normally closed operations depend upon orientation. i.e.If the magnet floats away or towards switch.

Detects rise or fall of liquid, as well as liquid flow or predetermined volume. Design allows fitting to be achieved both as an internal operation or externally if necessary.

NOTE:- Suitable for control/signalling only ref: wattage.

The switching performance can be drastically affected if switch
ratings are exceeded. Inductive, capacitive and tungsten filament
lamp loads derate by 50%. All switch ratings are at DC resistive loads.
