1 = temperature – 40°C to + 85°C

KSC Tact Switch for SMT

See page A-25

With or without actuator

Positive tactile feedback

Operating force from 1.1N (110 grams)

to 5.5N (550 grams)

Typical travel from 0.3 mm (0.118) to

0.75 mm (0.295)

Tin plated terminals for easy soldering

Gullwing or J-type terminals

Adapted to the main soldering

methods of surface mounted

components (SMT)

Packaging:

KSC1, KSC2 and KSC3 are delivered on continuous tape in reels of 2000 pieces,

KSC4 in reels of 1000 pieces. Dimensions of reels according to EIA RS481 or IEC 2863.

External diameter 330 mm ± 2 mm.

Soldering:

Depending on the application of the KSC, this component is suited to the following methods:

Flow soldering

– The KSC terminals being SnPb plated over a Nickel barrier, the use of slightly activated ﬂux

– Soldering on double wave machine. The bath temperature is generally 255°C ± 5°C

– Cleaning according to usual washing processes.

Vapor phase reﬂow soldering

Infrared reﬂow soldering

Conductive inks
