KL series
Locking rocker switches
Distinctive features
Unlocking actuator
Protection frames
Unlocking actuator
Each KL rocker switch includes an unlocking actuator.
This actuator must be pressed to activate the protected function of the rocker.
Moreover, two frames protect the unlocking actuator from untimely activation.
This intuitive and secured ergonomics is patented by APEM.
