The switch preparation BRÜHL-SV® is mainly used for all BRÜHL doors, if safety switches are prepared in the factory (for quick installation on site) to fit exactly. In this system preparation, the safety switch is function-dependent and can consist, for example, in a hole pattern adaptation on the mullion / door leaf as preparation for an escape release, in special hole pattern and welding substructure adaptations. We offer safety switches from ABB, Bernstein, Euchner, Fortress Interlocks, Leuze electronic, Omron Electronics, Pilz, Rockwell Automation and Schmersal.
