Abstract
A finger-actuated rotary switch adapted for use in electric devices, such as lanterns, and operative to select a desired light or light combination wherein the rotary switch is a waterproof structure and includes an elongated rotatable stem extending through a stator and having a switch rotor retained on one end thereof. The switch rotor is in engagement with the stator and relative movement between the switch rotor and the stator is effective to move the switch rotor into and out of engagement with electrical contact heads extending from the stator all in response to movement of cam followers which extend from the switch rotor and move along and in engagement with a cam surface on the stator. The switch rotor is resiliently maintained in engagement with the stator. A support is positioned between the stator and an operating knob on the stem.
