Common signal must not
be linked to the ground
due to Actuator conductive
EPDM raw material
This actuator is not compatible with grease even with restricted contact.
In case of the integration of an actuator or button by the customer, please consult us if use of plasticizer agent for button
raw material (risk of chemical migration).
Our actuator contains carbon particles and is electrical conductive. In consequence, customer actuator must be electric
insulating raw material.
Due to the cover raw material plating, small tin balls can appear after the reflow soldering process. These small tin balls
are located near all cutting areas.
