Soldering
Manual Soldering
Device Soldering iron
Please refer to MFS Series Heat-resistant Table
shown below.
Auto Soldering
MFS series are not compatible with auto soldering.
Soldering should be done manually.
When soldering two or more terminals to the common
land, use solder resist to solder them independently.
Flux Cleaning
Solvent : Fluorine or Alcohol type.
MSF Series are not process sealed. If the PC board is to be
cleaned, clean the soldering surface of substrate with a brush
so that the switch is not exposed to the cleaning solution.
Frequency of switch use
If the switch is not likely to be operated frequently(e.g.
two or three operations a year) in the dry circuit area,
a sulfide film is likely to be formed on the contacts,
resulting in contact failure. If this is the case, gold-
plated products are recommended. Please contact your
local Nidec Copal Electronics sales representative.
