Cautions and Warnings:
The following conditions apply to all DIP Switches (hereinafter referred as to “switch” or
“DIP switch”) of Würth Elektronik eiSos GmbH & Co. KG:
General:
• This switch is designed and developed with the intention for use in general electronics equipment.
• Before incorporating the switch into any equipment in the field such as aerospace, aviation, nuclear control, submarine, transportation,
(automotive control, train control, ship control), transportation signal, disaster prevention, medical, public information network etc. where
higher safety and reliability are especially required or if there is possibility of direct damage or injury to human body, Würth Elektronik
must be asked for a written approval.
• In addition, even switches in general electronic equipment, when used in electrical circuits that require high safety, reliability functions or
performance, the sufficient reliability evaluation-check for the safety must be performed by the user before usage.
• The switch is designed and manufactured to be used within the datasheet specified values.
• Do not use the switch outside the datasheet specifications.
• Prevent any damage or scratches on the switch, especially on the actuator.
• Direct mechanical impact to the switch shall be prevented (e.g. overlapping of the PCB´s).
• The responsibility for the applicability of the customer specific products and use in a particular customer design is always within the
authority of the customer. All technical specification for standard products do also apply to customer specific products.
Product Specific:
Soldering:
• The solder profile must comply with the WE technical soldering specification; otherwise, the warranty will be void.
• For reflow soldering limitation of two times is recommended. Hand soldering max. 350°C for 3 sec max..
• Other soldering methods (e.g. vapor phase) are not verified and have to be validated by the customer on his own risk.
Cleaning and Washing:
• Non-washable series are parts without ‘washable’ label in the catalog:The switch is not constructed for washing, so washing can cause
malfunction afterwards.
• ‘Washable’ series are those with ‘washable’ label in the catalog: Cleaning agent that are used to clean the customer applications might
damage or change the characteristics of the switch, body, pins and termination.
• Please do not submerse our washable products into water or cleaning agents or put them in locations exposed to water completely.
• Do not clean washable series immediately after soldering. The cleaning agent may be absorbed into the switch through respiration while
the switch cools.
• When cleaning by hand (brushing), please do not use excessive force on our switch to avoid malfunction afterwards, otherwise relevant
areas for the function of the switch might get deformed.
Potting and Coating:
• If the switch is potted or coated in customer applications, the potting or coating material might shrink during and after hardening; thus
the switch is exposed to the pressure of the potting material with the effect that the switch possibly might get damaged by this pressure
with the outcome that the electrical as well as the mechanical characteristics are in danger of being affected. After the potting or
coating material is cured, the switch needs to be checked if any malfunction or destructions on the switch has occurred.
Handling of Product:
• Please keep our switch at “off” position before and during the soldering process.
• For series with top tape, please remove the tape after your manufacturing process is completed.
• A ball pen or plastic tweezers with flat and smooth surface (the latter is recommended to be used to switch the actuator position).
Please do not apply excessive force as it could damage or deform the contacts inside the switch and this may lead to malfunction of the
switch.
• Do not use sharp headed tools to operate the switch. Sharp headed tools may damage the switch surface and could result in
malfunction of the switch.
Correct setting steps:
1. For the top-tapped DIP switches, do not remove the tape until the soldering process is completed.
2. Use one side of the tweezer’s lever to touch the cover of the switch, the other side of the tweezer’s lever touches the opposite side of
the moveable actuator, then clip vertically to move the actuator to the switch’s cover side.
3. Use clamping force to switch the actuator.
• Please follow the aforementioned ‘Correct setting steps’ and do not use the closed-lever tweezer to push or poke the actuator. Extensive
and unbalanced force may damage or deform the contacts and/or the slide window, thus undesirable failures may occur.
• Please do not switch the setting to ‘On’ or ‘Off’ until the PCB is fully cooled down.
• Design the right angle part with consideration of the wave soldering process so that the parts will not touch the soldering wave during
soldering process or protect the switch part with cover fixture. Melt of the switch might cause malfunction.
Operation and Storage conditions:
• -40°C ~ +85°C
• Product shall be used before the end of the period of 12 months based on the product date code, if not, 100% solder ability cannot be
warranted.

This electronic component has been designed and developed for usage in general electronic equipment only. This product is not authorized for use in equipment where a higher safety standard and reliability standard is especially required or where a failure of the product is reasonably expected to cause severe personal injury or death, unless the parties have executed an agreement specifically governing such use. Moreover Würth Elektronik eiSos GmbH
& Co KG products are neither designed nor intended for use in areas such as military, aerospace, aviation, nuclear control, submarine, transportation (automotive control, train control, ship control), transportation signal, disaster prevention, medical, public information network etc.. Würth Elektronik eiSos GmbH & Co KG must be informed about the intent of such usage before the design-in stage. In addition, sufficient reliability evaluation checks for safety
must be performed on every electronic component which is used in electrical circuits that require high safety and reliability functions or performance.
