Air Operated Switches, 1 Pole Elements, Surface Mount/Through Panel

Air Operated Switches, 1 Pole Elements, Surface Mount/Through Panel

The air operated switch system offers enhanced safety in hazardous areas by allowing remote operation of electrical circuits.
The actuator is a bellows which, when compressed moves air down the air tubing to the switch element. This compressed air then expands a bellows in the switch, which operates the electrical contacts.
When used in wet environments or where electrical switching would be dangerous due to arcing, the switch and all electrical wiring can be located outside the hazardous area giving the operator total electrical isolation for the equipment.
Such applications include: Battery charging rooms, laboratories, garages, or wherever explosive gases, vapours or powders may exist.

When assembled the air switch and actuator form a sealed system, therefore temperature variation will cause pressure changes, which can in extreme cases affect the performance of the switch. To prevent this the total volume of the system must be kept below a critical value for a given temperature range and, to this end, a maximum length of air tubing (and hence volume) can be given for any combination of switch and actuator.
The additional data tables give these lengths in metres; for moderate and extreme temperatures.
Single-pole momentary or latching air-operated switch suitable for use with all air actuators and accessories
Two types are available, surface mounting with side connection of the air tube or through panel fixing with the air tube connection via the base
The latter type is ideal where it is required to seal all electrical connections from the environment in an enclosure
Through panel fixing is by means of a 9/16 UNF nut (supplied) or may be surface mounted using the additional 3.2mm dia fixing holes, suitable for M3 or No. 6 self-tapping screws
SPDT microswitch contacts are rated at 15A 250 Vac/30Vdc and connection is via 250 ( 1/4 in) terminals. Operating temperature range -10°C to +60°C
