We see from your search that you're looking for information on the term "Position Switches",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release Safety switches prevent tampering from
Moeller Electric, which we summarised at the time by saying "The LS range includes switches with separate actuators, door switches with spring or magnet-powered retained actuators and switches for hasp and hinge operation".
A few weeks before,
we featured the news release Automation project completed for sewage facility from
Rotork Controls: "The hoists and chains were replaced with threaded rising stems, operated by Rotork IQ Pro Model 35 actuators and IB7 bevel gearboxes".
In February 2007, we covered the news from Functional Safety Engineering
concerning its AS-Interface Safety at Work
- take a look at More than just another safety bus
which says: "Users can now depend on AS-Interface Safety at Work for all their safety requirements on site, from the simplest networking system available for low level field devices".
Take a look also at the news release from Techno-Isel, Belt driven slides offer many options,
as well as Cylinders claim exceptionally long service life from Parker Hannifin,
and Position switches meet safety and Ex standards from Steute.
