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
