Two-, Three-, Four-Position Selector
Switches
Model Chart
These switches are manually operated devices
adaptable to a wide variety of applications in
pneumatic control systems. They are normally
used to perform diverting or supply and exhaust
functions to operate final control components or
index relays in multiple switching systems.
The S520 is a two-position, four-branch switch. The
S521 is a two-position five-branch switch that
provides one blocked port in each knob position.
The S530 is a three-position, four-branch switch
which can be used to supply a signal to any one of
three devices or supply any one of three signals to
a device. Its unused ports are blocked. The S531 is
identical except for its unused ports being
exhausted to atmosphere.
The S540 and S541 are four-position, five-branch
switches which follow the same operating pattern
as the S530 Series. However, they can supply a
signal to any one of four devices or vice-versa.
Unused ports are blocked in the S540 and
exhausted in the S541.
