Rotary Switches
Single Deck Rotary Switches
ADjuStABLE StOPS: Style D
Adjustable stops permit the user to set and reset
the number of positions per poles. Shown in
the diagram, a plastic washer can be removed
to reveal slots at the base of the bushing. Stop
blades can be inserted into the appropriate
slots to limit switch rotation. Positions per pole
configuration can thus be changed to meet the
needs of the application. Dimensions are the
same as the fixed stop version, when plastic
washer is in place. Most desirable for prototype
work. Readily available from local distributor.
Shaft and panel seal switches
are watertight to the panel. They
are not totally process sealed
like the Style “T”. Panel is sealed
by a gasket at the base of the
bushing. Shaft is sealed by an
O-ring inside the bushing. After
mounting, seals do not alter
switch dimensions. See Style
“S” (standard switches) and
Style “M” (military switches) in
the Choices and Limitations
chart.
SHAFt AND PANEL SEAL: Styles S and M
SCREwDRIvER SLOttED SHAFt: Style B
Form, fit and function equivalent
to standard shaft switches. The
dimensions shown have evolved
as the most popular for this
type of switch. See Style “B”
in the Choices and Limitations
chart. Previous users may
have ordered these switches
by a non-descriptive part num-
ber containing a “Y”. Contact
Grayhill, if in doubt about a
cross-reference.
MEtRIC SHAFt AND BuSHINg: Style E
Metric standard dimensions
for the shaft and bushing are
shown in the drawing. Other
dimensions approximately the
same as shown in dimensional
drawing. Contact Grayhill for
exact dimensions. See Style “E”
in the Choices and Limitations
chart.
