Usage guidelines
How to get the best results with MEC Switches?
These guidelines are offered to users of MEC Switches as an aid to
ensure successful and reliable switch operation.
Temperature
Both unimec™ and multimec® switches are produced in low and high
temperature versions. Please see the technical specifications for details on operating and storage temperatures and soldering guidelines
to make sure you select the best switch for your application. When
wave soldering is taking place, MEC strongly recommend that the
temperature profile is analysed and compared with the temperature
rating of the switch. In case of doubt always select the high temperature versions unimec™ 154XX, and multimec® 5XXH9XX. It is also
important to monitor the accumulated heat build up from both the
pre-heat zones and the solder zone.
Most standard accessories for both unimec™ and multimec® switches
are made from ABS plastic with a maximum operating temperature of
65°C. It is strongly recommended that accessories are mounted after
soldering of the switch. If this is not possible care must be taken not
to overheat the accessories during the soldering process. The 1SS,
1GAS/1GCS and Varimec™ caps are, however, made of high temperature materials and will meet the same temperature specifications as
the high temperature switches.
For accessories made from other plastic materials please see multimec® and unimec™ technical specifications.
LEDs have their own temperature specifications. When fitted in a high
temperature switch the LED will determine the max. operating temperature, i.e. 5GTH93524 has an upper temperature limit of 85°C!
This also applies with 3F switches.
Mounting and Dismounting
If switches are to be mounted in rows it is essential that the recommendations regarding spacing are followed. PC board thickness
should be 1.4±0.2 mm and terminal hole diameter should be 0.9mm.
All unimec™ and multimec® caps and bezels are easily snapped onto
the switch modules and can be changed at a later time with the exception of the unimec 16.700 cap. The same applies to the 3E caps. Once
these caps are installed they are not designed to be removed. To do
so may cause damage to the switch and the PC board if not done
very carefully. If the 16.300 or 16.700 cap must be removed from a
unimec™ alternate action switch, make sure that the switch actuator is
in the released, upper position before attempting to remove the cap.
This will prevent possible damage to the internal latching pin.
Care must be taken when inserting the 3FT switch and LED assembly
into the PC board. Do not press direct on the LED. This will force the
LED down into the actuator and risks to cause the switch contacts to
remain in the closed position. To correct the fault, the LED must be
raised slightly and centered in the actuator to assure unrestricted
movement of the actuator. A mounting tool is available for multimec®
switches.
Soldering and Cleaning unimec™
Most assembly and field problems experienced by users of unsealed
switches are caused by the contamination of the contacts during
soldering and cleaning.
Contact contamination may be recognised by an increase in contact
resistance and possible intermittent operation of the switch, especially in low power applications. Care must be taken not to submerge
the switch in cleaning agents or spray the switch during cleaning. The
switch must be protected at all times to prevent contamination by flux
or cleaning liquids.
For unimec™ alternate versions we recommend to leave the actuator in the released upper position during soldering. This makes the
switch more resistent to overheating.
Soldering and Cleaning multimec®
multimec® switches are fully sealed to IP67 specifications to prevent
solder flux and aqueous based cleaning solutions from entering the
switch and contaminating the contacts. The switches can be placed on
the PC board with other components and wave soldered. multimec®
offers a high level of sealing, however, with aqueous solvent solutions care must be taken to avoid the worst case situation with water
jets, complete immersion into a liquid with a temperature below the
board or surface tension reducing additives.
Recommended cleaning methods are demineralized water. Any surface tension reducing agents, such as soap, must not be used as they
risk causing a potential leakage of the switch.
Soldering - Through Hole Versions
Hand soldering: Max. 350°C for max. 3 sec., this applies for both low
temperature and high temperature versions.
Wave soldering: heat built up in the switch during pre-heating and
soldering must not exceed the maximum operating temperature of
the switch. If, for some reason, a high pre-heating temperature is
required, MEC recommend the high temperature switches. In any
case peak temperature must not exceed 260°C, and soldering time
is max 10 sec.
Soldering - Surface Mount Versions
For all methods - infrared, convection and vapour phase. The upper
limit 260°C/30 sec must be observed. The soldering temperature
profile must have moderate temperature gradients.
RoHS Compliance
As of 1 July 2006 MEC has completed the conversion to RoHS compliance. For more info please see our homepage www.apem.com
Temperature Limits:
Low temperature switch 115°C
High temperature switch 160°C
