The switching function can be changed by turning the electric upper
part by 180° (normally closed contact or normally open contact). The
state on delivery is a normally closed contact. By inductivity in the
direct current circuit the use of suitable protection circuit should be
considered. Further maintenance indicator details and designs are
available in the maintenance indicator data sheet.

We draw attention to the fact that all values indicated are average
values and do not always occur in specific cases of application. Our
products are continually being further developed. Values, dimen-
sions and weights can change as a result of this. Our specialized
department will be pleased to offer you advice.
