Their robust polyetherimide (PEI) housings make for greater resilience when exposed to extreme temperatures, improved resistance to chemicals and 50% more shock resistance compared with polycarbonate.
The amber-coloured, transparent snap-action switches are ideally suited for applications where impact forces are high and frequent as in door systems of railway vehicles. They are highly recommendable for use in products exposed to aggressive chemical influences or extreme temperatures (-55°C to +150°C). They are also suitable for offshore applications such as wind turbines as well as for printing machines.
