OPTIONS
Adjustable Stops
Set and reset stops to limit rotation. All
dimensions are the same as for fixed stop
switches. Switches are shipped with the stop
blades located to limit rotation to 11 switch
positions. For continuous rotation, remove both
blades. For limited rotation, remove the 2nd
(clockwise) blade and move it to the hole
located between the positions shown in the
Truth Tables. Removal of a plastic washer
provides access to the blades and slots.
Adjustable stop versions are available in
unsealed styles only.
Shaft and Panel Seal
Switches are available in sealed or unsealed
styles. For sealed style, the panel is sealed by
an o-ring at the base of the bushing. The shaft
is sealed by an o-ring inside of bushing. After
the switch is mounted, seals do not alter the
dimensions of the unsealed style.
Additional Characteristics
Contact Type: Wiping contacts
Shaft Flat Orientation: Switch position is
defined as that position that is opposite the
shaft flat. The location of the contacts in
relation to the shaft flat is shown on the circuit
diagram.
Terminals: Only the active position terminals,
as shown in the circuit diagram are supplied
with the switch. All common terminals are
supplied.
Stop Strength: 7.5 in-lbs minimum
Rotational Torque: 8 to16 in-oz
Bushing Mounting: Required for these
switches
Maximum Mounting Torque: 15 in-lbs.
