Description
The Type 304 and 304L switches are normally
mounted on a control valve actuator to operate
alarms, signal lights, relays, solenoid valves, or other
equipment when valve travel reaches predetermined
points.
The Type 304 position switch (see figure 1) is for ap-
plications that require only one or two switches. The
Type 304L position switch is for applications that re-
quire three or more switches with a maximum of six
switches (see figure 3). The individual switches can be
adjusted to operate at any point of travel within the 90
degrees of cam rod rotation.

1. Contact your Fisher Controls sales office or sales representative for information for
mounting on actuator types and sizes not listed.
Installation
When Type 304 and 304L switches are ordered with
an actuator, the factory mounts the position switch and
adjusts the cams for the travel specified on the order.
When installation is complete, the cam adjustments
should be checked as described in the adjustment pro-
cedures.
If the position switch has been ordered separately, or
removed for maintenance, refer to the appropriate pro-
cedure for mounting.
Mounting the Position Switch on the
Actuator
To mount a Type 304 or 304L position switch on a
Fisher Controls actuator in the field, see the additional
actuator parts for field mounting section of the parts
list. These additional parts, plus those parts listed in
the position switch mounting parts section, are re-
quired for some actuators.
Refer to the appropriate actuator instruction manual
for procedures to disassemble and assemble actuator-
to-valve connections if required.

WARNING
Avoid personal injury from sudden re-
lease of process pressure. Before disas-
sembly:
DDisconnect any operating lines pro-
viding air pressure, electric power, or a
control signal to the actuator . Be sure the
actuator cannot suddenly open or close
the valve.
DUse bypass valves or completely
shut off the process to isolate the valve
from process pressure. Relieve process
pressure from both sides of the valve.
Drain the process media from both sides
of the valve.
DUse lock-out procedures to be sure
that the above measures stay in effect
while you work on the equipment.
DVent the power actuator loading

tion must be with an approved meter for
hazardous areas in order to avoid person -
al injury or property damage caused by an
explosion or fire.
WARNING
Refer to the appropriate actuator
instruction manual before removing the
actuator-to-valve connection. Personal
injury or property damage may result
from sudden release of preloaded
spring force.
Generally, the position switch is attached to the
mounting plate with machine screws, and the mount-
ing plate is installed on the actuator. Then, the con-
necting linkage or coupling between the actuator and
position switch is installed.
Refer to table 4 for references to the assembly draw-
ing figures that show typical installations of the posi-
tion switch.
After mechanically connecting the position switch to
the actuator, refer to the electrical connections and
operating information sections to place the position
switch in operation.
Mounting the Position Switch on Other
Devices
For other applications of the position switch, provide
suitable mounting hardware. If the motion of the moni-
tored device is linear, provide a lever arm to convert
the linear motion to rotary motion. The lever arm
should be limited to 90 degrees of rotation from the
point at which the first switch actuates. This ensures
that the first switch remains actuated until the input
motion is reversed.
If the motion of the monitored device is rotary, the
switch can be coupled directly to the device if the
rotary motion does not exceed 90 degrees from the
point at which the switch first actuates. If the rotary
motion of the device is greater than 90 degrees after
the first switch actuates, provide a gear and/or lever
arm to reduce the rotation to 90 degrees or less.
After connecting the switch to the device, refer to the
electrical connections and operating information proce-
dures to place the position switch in operation.

Electrical Connections
Make the required electrical connections through the
conduit connection in the base (figure 3). Use a suit-
able conduit connector for hazardous locations. If the
unit is equipped with an optional terminal strip, make
connections to the strip. If the unit does not have a
terminal strip, make connections directly to the individ-
ual switches. A ground terminal connection is provided
by the green wire retainer and screw in the base.
CAUTION
For explosion-proof applications, install
a suitable conduit seal no more than 18
inches (460 mm) from the position
switch. Personal injury or property dam-
age may result if seal is not installed.
To obtain a normally-closed circuit (the circuit for an
individual switch is closed until the switch is actuated),
wire to the C (common) and the NC (normally-closed)
terminals. To obtain a normally-open circuit (the circuit
for an individual switch is open until the switch is actu-
ated), wire to the C (common) and the NO (normally-
open) terminals.
Unless specified otherwise on the order, switch 1 (the
switch closest to the base) changes state (changes
from mornal to actuated) at the valve-closed position.
Unless otherwise specified, the switch farthest from
the base changes state (changes from normal to actu-
ated) at the valve fully open position. Refer to figure 4
for standard switching conditions.

WARNING
On an explosion-proof instrument, re-
move electrical power before removing
the instrument cover in a hazardous
area. Personal injury or property dam-
age may result from fire and explosion if
power is applied to the instrument with
the cover removed in a hazardous area.
1. Position the valve or monitored device at the point
of travel where actuation of a particular switch is de-
sired.
2. Open the circuits between the switch and power
supply, and remove the switch cover.
3. Refer to figure 3. Use a light or ohmmeter to indi-
cate switch actuation. Insert a screwdriver into the
geared nut of the appropriate switch and pry against
the cam ear. Rotate the cam until its small radius (see
figure 5) contacts the lever arm roller and actuates the
switch. Tension provided by a spring washer holds the
cam in place.
4. Always adjust the cams so that the small radius of
the cam actuates the switches. This minimizes the
differential travel (dead band) required to make and
then break the circuit. The switch should not actuate
on the heel of the cam; this increases the dead band.
5. To ensure switching at the open and closed valve
positions, set the switch to actuate approximately
1/32-inch (0.8 mm) before the valve reaches these
positions.
6. The lever arm roller is preset at the factory approxi-
mately 1/16-inch (1.5 mm) from the 3/8-inch (9.5 mm)
radius of the cam, as shown in figure 5. Adjust this
dimension by turning the adjustment screw on the
switch lever arm. Use the adjustment screw only to
position the lever arm in relation to the cam; do not
use the screw to adjust the point at which the switch
actuates.
7. Replace the cover (key 2).
Principle of Operation
When used with sliding-stem valves, the operating arm
(key 49, figure 7) converts linear valve travel to rotary
motion of the cam rod.
When used with rotary shaft valves, the coupler (key
105, figure 16) links the position switch and the rotary
actuator directly and rotates the cam rod.
As the cam rod rotates, cams mounted on the rod
contact the switch rollers and actuate the switches,
which opens or closes individual switch circuits.

Type 304 & 304L
7
As the actuator stem travels downward (for sliding-
stem valves) or as the valve shaft rotates counter-
clockwise (for rotary valves), the switch roller rides up
on the small radius of the cam lobe, actuates the
switch, and rests on the lobe during the remainder of
the travel. The normal or un-actuated position of the
switch is with the roller positioned over, but not touch-
ing, the 3/8-inch (9.5 mm) radius of the cam as shown
in figure 5.
Maintenance
WARNING
Avoid personal injury from sudden re-
lease of process pressure. Before disas-
sembly:
DDisconnect any operating lines pro-
viding air pressure, electric power, or a
control signal to the actuator . Be sure the
actuator cannot suddenly open or close
the valve.
DUse bypass valves or completely
shut off the process to isolate the valve
from process pressure. Relieve process
pressure from both sides of the valve.
Drain the process media from both sides
of the valve.
DUse lock-out procedures to be sure
that the above measures stay in effect
while you work on the equipment.
DVent the power actuator loading
pressure and relieve any actuator spring
precompression.
WARNING
For 304 switches in intrinsically safe
areas, current monitoring during must
be with an approved meter for hazard-
ous areas in order to avoid personal in-
jury or property damage caused by an
explosion or fire.
Refer to figure 6 for key number locations.
WARNING
On an explosion-proof instrument, re-
move electrical power before removing
the instrument cover in a hazardous
area. Personal injury or property dam-
age may result from fire and explosion if
power is applied to the instrument with
the cover removed in a hazardous area.
To replace switches, open the circuits between the
switch and power source, and unscrew the cover (key
2). Record the wire connections to the defective switch
or switches. Remove the hex nuts, lockwashers, and
end plate (keys 10, 8, and 9). Remove any spacers
(key 18). Disconnect the wires from the switches, and
slide the switches off the switch posts (key 4). After
replacing switches, attach the wires as recorded. Ad-
just the switch cams as described in the Adjustment
section.
To minimize the possibility of moisture entering the
switch, inspect and replace the O-rings (keys 24 and
26) as necessary. To replace the small O-ring (key
26), first remove the cover (key 2). Then remove the
E-ring (key 16). Remove the hex nuts, lockwasher,
and end plate (keys 8, 9, 10, and 17) from the switch
post (key 4). Carefully remove the cam rod (key 11)
from the base (key 1). Then, remove the small O-ring
(key 26). Apply an appropriate lubricant to the O-ring.
When reassembling, lubricate the portion of the cam
rod that contacts the bearing in the base with a good
quality grease. Follow this procedure in reverse to re-
place the O-ring and cam rod.
The large O-ring (key 24) is held in place by the cover
(key 2). With the cover removed, slide the O-ring off
the base (key 1), inspect and replace the O-ring (key
24) as necessary. Apply an appropriate lubricant to the
O-ring, and slide the O-ring into position on the base.
Apply an appropriate lubricant or anti-seize compound
to the threads on the base, and replace the cover.
CAUTION
The presence of Fisher Controls person-
nel and also approval agency personnel
may be required if you service (other
than normal, routine maintenance, such
as calibration) or replace components in
an instrument that carries a third-party
approval. When you replace compo-
nents, use only components specified
by the factory. Substitution with other
components may void the third-party
approval. Always use proper compo-
nent replacement techniques. Poor
quality repairs can impair the safety fea-
tures of the device.
