1. Purpose
C&K components, as design and manufacturing company for micro-miniature tact switches, set up
continuous product improvement to go toward zero defects.
This continuous improvement action leads to implement a major modification on the KSC tact switches
series: anti particle central contact will be placed on the lead frame in order to increase product
robustness to dust or particle contamination. In addition, new injection tooling & methods will allow
better over-molding parameters to improve process stability.
Those modifications will make for our customers a significant reduction of any issue linked to the
particle failure mode.

Lead frame modification to include several points of contact between the central contact and the
dome. Other modifications such as terminal position on the plastic housing, ejector location and
Central contact round shape allow, in particle presence, to catch it inside the contact. The radius
size has been calculated according the most common particle size.
Other modifications such as terminal position on the plastic housing.
New mold with new injection parameters location such as ejector, injection pin and parting line.
