Description
FUJI cam-type control switches are
recommended for use on switchboards,
control panels and switchgear because
of their reliability in service. The main
type is RC310 with operational current
ratings of 10A.
Simplified and economical circuits can be
designed around the RC310, since it can
handle loads of up to 10A at 220VAC
without the need of contactors. Typical
examples of complex circuits based on
the attractive features of these
economical cam-type selector switches
are given on pages 04/265 to 04/268.
FUJI is prepared to manufacture other
versions to suit your particular
applications, and switches with up to 12
selector positions can be made to order.
RC310 switches are normally supplied
with H-type handles. Alternative handle
shapes available include the pistol-grip
P-type, cane-handle shaped S-type and
rosette shaped R-type.
Switches with a 2-12 position maintained
type, 3-position center spring-return type
and center spring-return type with locking
device are also available.
