6. Prohibitions and precaution for handling
In order to prevent accidents or performance deteriorations in use of the product,
observe the following restrictions and pay attentions to the following items.
<Restrictions>
1) Wave soldering(by solder bath dwelling)is prohibited because this switch does not have
a capability. Therefore, be sure to perform soldering by reflow method.
2) Do not put this switch into the washing process after soldering because this switch
does not have a capability of washing even water.
6.1 Reflow soldering condition
1) Three times max.It is possible to conduct reflow soldering with switch side down after at
least one time soldering with switch up, but the drop of switch from the PCB and/or flux
ingress might happen depend on your manufacturing/soldering condition.
So please check if these phenomena do not happen with your manufacturing/soldering process.
2) Re-soldering by soldering iron shall be allowed under 350℃ max. 3 sec. max. 1 time only
and the tip of iron must not touch to terminals.
Soldering iron for re-soldering have to be 60W max.
3) Do not put any object such as a weight etc. on the operating knob.
4) Please use the solder paste which includes flux of 11% or less.
6.2 Design instructions
1) Please refer to the land pattern plan Panasonic recommends on the 2nd page.
2) Design key top as fig-1. Design inclination of key top 5 deg. max. as fig-2 and fig-3.
In order to protect the switch from direct impact, install the stopper as fig-4.
Tolerance between switch and key top is within 0.3mm .as fig-5.
(Recommended operation condition)

6.3 Notes
1) Please use caution not to give excessive static load or shock.
Do not apply load to the switch except to the operation part in the operation direction.
2) In case of this switch to be mounted to the edge of P.W.B., please avoid flow soldering
on any other parts after this switch is mounted as flux may enter into the switch.
3) Storage under high temperature, high humidity, or corrosive gas should be avoided.
When a long period of storage is required, please keep the carton unopened.
4) Please avoid any usage under the condition that switch to be continuously pressed to
ON position for a long time.
5) Please do not wash or clean the switch with water or an organic solvent.

6) If a large amount of solder paste is applied around the switch, flux from solder
paste may enter into the switch. Therefore please embrace our recommend land pattern
and solder mask specified in this specification. Please also avoid any additional
land patterns around the switch on P.W.B.
6.4 Attentions Required for Circuit Condition
6.4.1 Rating
(1)In order to assure the reliability, use this product within the rating range specified in
the Specifications.
(2)Rated power is a maximum value of the power which can be continuous load at rated ambient
temperature.
(3)If the product is used over the rated power, the correct characteristics may not be gained
or the product may be burnt.
(4)The circuit shall be designed to avoid the inrush current to the switch, also avoid the
surge voltage to be applied.
(5)When the switches is used under a few μA(dry circuit),contact resistance may affect
circuit property, so please use the switch under specified switch rating.
6.4.2 Attentions Required for Bouncing and Chattering
In order to prevent the malfunction by chattering caused by bounching at switch-operation
of ON/OFF and external vibration etc., please pay attention to the design shown below.
1) Read several times.
2) Set the delay time.
3) Set the CR integration circuit.

(Except applications considered appropriate countermeasure)
Avoid using this product in a place where it is directly exposed to the wheather,
or where humidity is high caused by steam and dew condensation, etc.
6.5.3 The product is not a sealed type.
Avoid the use under following circumstance and conditions as it may affect a bad
influence to characteristics.
(1) In the corrosive gas atmospere, such as Cl 2, H 2S, NH 3, NOx, SO 2 gas.
(2) Waterdrop remained, dew condensation, Waterdrop adhered.
(3) In the solution of water, sale water, oil, chemicals, and organic solvents.
(4) A place where it is exposed to direct sunlight.
(5) A place with large amounts of dust or dirt particles.
6.5.4 The structure of this product is not waterproof, chemicals resistance and solvent
resistance. Do not wet with water, chemicals and/or solvents.
6.5.5 Do not apply the vibration, the shock (drop, etc.) or the pressure to this product
more than specified.
6.5.6 Push strength
In order to avoid damages of the switch, do not apply the load to the operating
section more than specified.
(If the load is applied more than specified, it may affect on the characteristics
of the push stroke, etc.)
6.5.7 Avoid the use of the switch under pushed ON condition is continued for a long time.
6.6 Repair･Service
6.6.1 When additional solder to the mounting soldering section of this product is to
be performed or soldering section is to be removed, pay attention not to apply
excessive stress and the temperature.
6.6.2 Pay attention not to melt the insulation material or the resin section, and avoid
deformation.
