MCS

Slide Switches

■Table of Part Numbers

RoHS Compliant

■Features

1. High Contact Reliability

Self-cleaning contact mechanism for high contact reliability.

2. Gold-plated contacts for low current applications

MCS222N-2018/MCS221N-2019

MCS422N-2032/MCS421N-2033

3. Designed for PC board mounting

■Soldering Speci cations

⑴Manual Soldering

Device ： Soldering iron

①350℃, Max.; 3 seconds, Max.

⑵When soldering two or more terminals to the common land, use

solder resist to solder them independently.

■Flux Cleaning

⑴Solvent : Fluorine or Alcohol type.

⑵MCS 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.

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.
