Safety switch for the UV lamp cover
The UV lamp cover is protected with a safety
switch. The safety switch has a reed switch and
comprises two components. The safely switch
ensures that the UV lamp only generates UV radia‐
tion in its fitted state. If the safety switch is
removed, then the UV lamp switches off. If the
safety switch is not fitted and thus remains closed,
e.g. after installation and maintenance work, then
the UV lamp cannot be started.
