Abstract
An improved switch interface is provided that does not rely on direct contact by the user interface element to the switch apparatus. This feature enables the switch to be enclosed within a sealed housing, thereby improving reliability and longevity of the switch mechanism.
Claims33
A portable light system, comprising:
- a. a sealed housing, wherein a portion of said housing is cylindrical in shape, said sealed housing including,
- i. at least one light element;
- and
- ii. at least one magnetic switch element configured to activate said at least one light element;
- b. a switch interface ring element configured to rotate radially around said cylindrical portion of said housing;
- and
- c. at least one magnet fixed in said switch interface ring element, said at least one magnet being operative to activate said at least one magnetic switch element within said sealed housing when rotation of said switch interface ring element radially around said sealed housing brings said at least one magnet in proximity to said at least one magnetic switch element.

A portable light system, comprising:
- a. a sealed housing, said sealed housing including,
- i. at least one light element;
- and
- ii. at least one switch element configured to activate said at least one light element;
- b. a switch interface element configured to move relative to a surface of said sealed housing without penetrating said sealed housing;
- and
- c. at least one switch activating element fixed in said switch interface element, said switch activating element being operative to activate said switch element within said sealed housing when movement of said switch interface element relative to said sealed housing brings said switch activating element in proximity to said switch element, wherein said switch interface element has a range of movement across said housing that spans a plurality of predefined positions, each of said plurality of predefined positions defining a position of a plurality of switch activating elements relative to a plurality of switch elements, each of said plurality of predefined positions defining a different switch setting.

A portable light system, comprising:
- a. a sealed housing, said sealed housing including,
- i. at least one light element;
- and
- ii. at least one switch element configured to activate said at least one light element;
- b. a switch interface element configured to move relative to a surface of said sealed housing without penetrating said sealed housing, wherein said switch interface element is fully removable from being coupled to said sealed housing;
- and
- c. at least one switch activating element fixed in said switch interface element, said switch activating element being operative to activate said switch element within said sealed housing when movement of said switch interface element relative to said sealed housing brings said switch activating element in proximity to said switch element.
