HAZARDOUS APPLICATIONS
Do not use foot switches on machines without point-of-operation protection.
Failure to follow these instructions will result in death, serious injury, or
equipment damage.
DANGER
Foot Switch Selection
Foot switches are used to control many industrial processes, while leaving the operator's
hands free to perform other functions. The type or model of foot switch suitable for each
application will vary depending on factors such as the control function required, degree
of protection required, production methods, unusual conditions, government regulations,
etc. In some applications more than one foot switch may be required, as when two or
more persons are operating a machine. In these cases, safe practice and regulations
require that the foot switches be wired in series making it necessary that each operator's
foot switch be actuated before the machine will cycle.
Only the user can be aware of all the conditions and factors present during setup,
operation and maintenance of the machine; therefore, only the user can determine which
foot switch(es) can be properly used. When selecting a foot switch for a particular
application, the user should refer to the applicable ANSI standards and OSHA
regulations. The National Safety Council's Accident Prevention Manual also provides
much useful information.
AW124
Type AW Fully Shielded Foot Switch with
Oversized Pedal Shield, Side Shields and Safety
Door. The Safety Door is interlocked with the pedal to
prevent operation due to shock or vibration. It
prevents accidental pedal operation by requiring a
simple but intentional motion to lift the door before
inserting the foot.
Operating Temperature:
–30 to +60 °C (–22 to +140 °F)
In some applications, such as power presses, additional operator protection such as
point-of-operation guarding must be provided when a foot switch is used as an actuator.
This is necessary since the operator's hands and other parts of the body are free to enter
the pinch point area and serious injury can occur. The shielding provided on foot
switches cannot protect an operator from injury. For this reason the foot switch cannot be
substituted for or take the place of point-of-operation protection.
A Trilingual Danger Sign regarding the need for point-of-operation protection is supplied
with each foot switch. The sign incorporates three languages: English, Spanish and
French. Additional copies of the sign are available by contacting your Square D sales
office.

[1] When ordering, add prefix “9002” to the catalog number.
[2] WARNING: These foot switches must not be used to operate machines or equipment where the possibility of operator injury exists. Typical uses include Emergency Stop functions, “Dead
Man” controls, signal functions (lights, bells, etc.).
[3] A single pole snap switch that contains two double break contact elements (1 N.O. and 1 N.C.) must be used on circuits of same polarity. A double pole snap switch contains two electrically
separated sets of contact elements allowing use on circuits of opposite polarity. Each set that contains two double break contact elements (1 N.O. and 1 N.C.) must be used on circuits of
same polarity.
[4] 2 N.O. and 2 N.C. isolated, direct acting contacts.
[5] For replacement cover drilled to accept latch. For Series C foot switches order AC9. No replacement cover available for Series A or B devices drilled to accept latch. AC8 is spring return
only.
