We see from your search that you're looking for information on the term "Safety Switch",
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 Twin-headed switches do double safety duties from
Euchner (UK), which we summarised at the time by saying "The use of a single safety switch for the control of two guards or doors has obvious cost cutting advantages".
A couple of weeks before,
we featured the news release Safety system monitors several guards from
Euchner (UK): "The CES-AR-C noncontact safety switch is particularly suitable for systems in which a large number of safety guards need to be monitored".
In September 2007, we covered the news from Pilz Automation Technology
concerning its PSEN ma1.3.
- take a look at Safety switches offer easy installation
which says: "The PSEN ma1.3 safety switch offers resistance to shock and vibration, an 8mm switching distance, an auxiliary contact as standard and an integrated status LED".
Take a look also at the news release from OEM Automatic, Safety switch suits tight applications,
as well as Noncontact switches offer durability from Pilz Automation Technology,
and New compact safety switch from Idem Safety from Idem Safety switches.
