The explosion-protected installation
switches are for use in the Zones 1, 2, 21
and 22. The materials used have proved
to be safe and reliable for both indoor
and outdoor installations, in particular in
chemical and off-shore plants. The robust
housings are made of a modified polyamide
material.
The large actuator surface of the installation
switch allows perfect operation, even when
wearing working gloves. A protective collar
prevents inadvertent operation. The toggle
has a luminescent label which is in accordance
with §7 of the Workshop Regulations and
is also free from radioactive additives. Due
to the external fixing facility, the switch can be
installed easily while the cover is closed. Cable
entry from the top is made possible by turning
the base. In special cases a through wiring is
possible as one can see on the illustration
opposite.
