KSC Tact Switch for SMT
KSC
Miniature tact switch designed to be
surface mounted (SMT) on PCB, single
pole, normally open contact.
Available in 4 versions:
KSC1: without actuator
KSC2: with short soft actuator
KSC3: with short hard actuator
KSC4: with long soft actuator
KSC5: with rocker option
See page A-25
KSC6: with long, soft actuation
Main features
ț With or without actuator
ț Positive tactile feedback
ț Operating force from 1.1N (110 grams)
to 5.5N (550 grams)
ț Typical travel from 0.3 mm (0.118) to
0.75 mm (0.295)
ț Tin plated terminals for easy soldering
ț Gullwing or J-type terminals
ț Adapted to the main soldering
methods of surface mounted
components (SMT)
ț This product is totally washable and
sealed according to EIA – RS-448-2
test and IP 67 (dust tight, protected
against the effects of immersion in
water)
ț Compatible with the major pick-and-
place machines
ț Delivered in thermoformed tape
and reels of 2000 pieces, KSC4 of
1000 pieces, KSC5 of 1000 pieces
and KSC6 of 750 pieces
Note: Identification
ț The 4th and 5th digits of KSC code
are stamped on the metallic top plate
ț The other characteristics of the code
can actually be seen on the product.

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
is suitable.
– Soldering on double wave machine. The bath temperature is generally 255°C ± 5°C
and soldering time Ͻ 5 sec.
– Cleaning according to usual washing processes.
Vapor phase reflow soldering
Temperature: 215°C;
Duration: up to 60 seconds
Infrared reflow soldering
Temperature: 200°C,
with peak of 230°C during 10 to 15 seconds
Conductive inks
Silver based inks can be used for the
connection of KSC on PC board.
Curing conditions depend on the type
of conductive ink.
