We see from your search that you're looking for information on the term "Safety Switches",
and we have a large number of manufacturers' news releases and technical articles here on Manufacturingtalk which will be of interest.
Let me be your guide.
Start with
the news release Safety position switches enhance protection from
Moeller Electric, which we summarised at the time by saying "Safety position switches offer a simple, efficient and cost-effective way of achieving enhanced protection for personnel and processes".
A couple of weeks before,
we featured the news release Guard interlocks minimise defeat possibilities from
Pilz Automation Technology: "Research into the reasons why operators try to defeat interlocks has shown that the need to defeat safety systems stems from shortcomings in the design of the machine".
In November 2007, we covered the news from Leuze Mayser
concerning its Solid 4E light curtain
- take a look at Safety light curtain protects hands and fingers
which says: "A range of light safety curtains has been expanded to include hand and finger protection following the introduction of a 14mm safety protection resolution".
Take a look also at the news release from Euchner (UK), Switch monitors several machine guards at once,
as well as Small CNC lathe has Y-axis and sub-spindle from HK Technologies,
and Non-contact safety switches show door status from Omron Scientific Technologies.
