K12S KEY DIFFERENTIATION
K12S Series is the first key switch on the market to combine SMT, high sealing
level and illumination features.
K12S KEY CHARACTERISTICS
K12S Series has been designed for harsh environment applications.
Featuring excellent tactile feedback, K12S Series provides a life cycle of more than
1,000,000 actuations, making it ideal for demanding conditions often found in auto-
motive, motorcycle, off-road transportation, industrial and medical applications.
K12S Series features abuse-proof contacts, 100N overload resistance, self-cleaning
golden contacts and low contact resistance (<100mΩ).
Packaged in tape and reel of 900 parts, the K12S SMT key switch can be mounted
on PCBs by pick and place equipment.

K12S CONFIGURATION OPTIONS:
K12S is proposed in different versions.
Fitted with a rubber cap the K12S Series is IP67(*) sealed. For applications where
IP40 sealing is sufficient, K12S can be proposed in “naked” version.
IP67(*) version
IP40 version
(*)IP67 is only applicable for the sealing between the switch and the rubber cap.
C&K recommends applying a resin on the PCB.
Without resin treatment, K12S is IP 6X (X = temporary immersion 0.5 m / 30 mn).

K12S Series concept separates electrical and mechanical functions, special combi-
nations of spring mechanisms and cam designs allow higher number of versions by
keeping same external form factor.
•
Standard actuation (with tactile feedback) or Detect (without snap point)
•
SPST (Single Pole, Single Throw) or DPST (Double Pole, Single Throw)
electrical function
•
NO (Normally Open), NC (Normally Closed) or other electrical
configurations (NO/NO, NC/NC or NO/NC)
•
“Double step” actuation
The K12S Series key switches offer an actuation force range of 1.5N to 12N,
with a total travel of 1.5mm. Customizable options (travels, actuation forces
and contact arrangements) are possible.
K12S Series (SPST versions) can be illuminated with the integration of a LED. Six
different colors are available as standard. Other LED colors can be proposed
based on customer’s specific requirements.
