Technical Information
Do not apply contact protective circuits as shown below.
Switching a DC inductive load is usually more difficult than switching
a resistive load. By using an appropriate contact protective circuit,
however, switching a DC inductive load will be as easy as switching
a resistive load.

Do not use the Switch for loads that exceed the rated switching
capacity or other contact ratings. Doing so may result in contact
weld, contact separation failures, or insulation failures.
Furthermore, the Switch may be broken or damaged.
Do not touch the charged switch terminals while power is
supplied, otherwise an electric shock may be received.
The life of the Switch varies greatly with switching conditions.
Before using the Switch, be sure to test the Switch under actual
conditions. Make sure that the number of switching operations is
within the permissible range.
If a deteriorated Switch is used continuously, insulation failures,
contact weld, contact failures, switch damage, or switch burnout
may result.
Do not apply excessive or incorrect voltages to the Switch or
incorrectly wire the terminals. Otherwise, the Switch may not
function properly and have an adverse effect on external
circuitry. Furthermore, the Switch itself may become damaged or
burnt.
Do not use the Switch in locations where flammable or explosive
gases are present. Otherwise switching arcs or heat radiation
may cause a fire or explosion.
Do not drop or disassemble the Switch, otherwise it may not be
capable of full performance. Furthermore, it may be broken or
burnt.
Fingertip operation is an important feature of Pushbutton
Switches. In terms of Switch operation, Pushbutton Switches
differ greatly from detection switches such as Microswitches.
Operating the Switch using a hard object (e.g., metal), or with a
large or sudden force, may deform or damage the Switch,
resulting in faulty or rough operation, or shortening of the Switch
life. The strength varies with the size and construction of the
Switch. Use the appropriate Switch for the application after
confirming the operating method and operating force with this
catalog.

This circuit effectively suppresses arcs
when the contacts are OFF. The capacitor
will be charged, however, when the
contacts are OFF. Consequently, when the
contacts are ON again, short-circuited
current from the capacitance may cause
contact weld.
This circuit effectively suppresses arcs
when the contacts are OFF. When the
contacts are ON again, however, charge
current will flow to the capacitor, which may
result in contact weld.

Snap-in Mounting
The pushbutton surface is composed of resin. Therefore, do not
attempt to operate the pushbutton using a sharp object, such as
a screwdriver or a pair of tweezers. Doing so may damage or
deform the pushbutton surface and result in faulty operation.
Switches can be broadly divided into two categories according to
mounting method: panel-mounting models and PCB-mounting
models. Use the appropriate model for the mounting method
required. Basically, panel-mounting Switches can withstand a
greater operating force than PCB-mounting Switches. If,
however, the panel thickness or the panel-cutout dimensions are
not suitable for the Switch, it may not be able to withstand the
normal operating force. With continuous mounting in particular,
select a panel of a thickness that is easily sufficient to withstand
the total operating force.
Panel-mounting Switches can be divided into two categories
according to the mounting method: snap-in mounting models
and screw-mounting models. Snap-in mounting Switches are
held in place with the elasticity of resin or a metal leaf spring. Do
not attempt to modify the spring after mounting. Doing so may
result in faulty operation or damage the mounting structure.
Mount screw-mounting models using the screws and nuts
provided (or individually specified). Tighten the screws to the
specified torque. Mounting with different screws or nuts, or
tightening beyond the specified torque may result in distortion of
the inside of the case or damage to the screw section.
Subjecting the Switch to severe vibrations or shock may result in
faulty operation or damage. Also, many of the Switches are
