This disclosure describes an effective slider switch mechanism that enables devices, e.g., smart glasses, to meet stringent liquid ingress requirements. The slider switch as described herein includes a mechanism that translates the linear motion of an external slider knob into rotational motion of a switch provided on an internal side of the device. A rotational seal such as a sealing O-ring is utilized to seal off the internals and provide liquid ingress protection. The described slider switch mechanism can provide unambiguous feedback to the user while providing liquid ingress protection.
