All types indicated in our catalog can work in contact with mineral oils, air and non-aggressive fluids. Please consult our technical office for other applications. There are available solutions to employ with oxygen, aggressive fluids or separation of fluids.
Choice of Models:
Choices are made after evaluation of the parameters of utilization, with particular consideration given to: -expected precision

-switching frequency

-electrical protection

-electrical load on contacts

Note: the difference between electronic micro-switches which can be rated for greater cycle life up to ten million, and the micro-switches of the electro-mechanical type which are rated for a mechanical life, without electrical load of one million cycles. On the practical side, the number of cycles is inversely proportional to the electrical charge applied and to the speed of insertion to which the micro-switch is subjected.
Selections based upon the Range of Work:

Excellent when the point of intervention finds itself at the center of the range of regulation.
Installation:
It is advisable to avoid installation near sources of heat, strong vibrations, aggressive atmosphere and wide changes of temperature.
Quality Check:
Before sale each of our instruments is tested independently in our firm under dynamic conditions of utilization. Each product is supplied with an enclosed certificate signed by the operator verifying the completion of all necessary testing. The stamped numbers on each instrument, identify the month, and year of delivery and the operator that it has executed the testing.

All our pressure switches are connected electrically with the following schematics:

Electromechanical type micro switch schem. No1                Electronic type micro switch schem. No2

Electric features of micro-switches are pointed in the following table:
