■Soldering

⑴Manual Soldering

Device ： Soldering iron

Please refer to MFS Series Heat-resistant Table

shown below.

⑵Auto Soldering

MFS series are not compatible with auto soldering.

Soldering should be done manually.

⑶When soldering two or more terminals to the common

land, use solder resist to solder them independently.

■Flux Cleaning

⑴Solvent : Fluorine or Alcohol type.

⑵MSF 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.
