Series connection of position switches 

In general, position switches may be connected in series if measures ensure that several 

protective doors are not regularly opened simultaneously (otherwise a fault cannot be 

detected). 
For safety level SILCL3 in accordance with IEC 62061, SIL3 in accordance with IEC 61508, 

and PL e (Cat. 4) in accordance with ISO 13849-1, however, they must never be connected 

in series, because every hazardous error must be detected (independently of the operating 

personnel).
