Abstract
A switch actuation device for use in connection with electrical switch mechanism having an actuatable structure. The device includes an actuation mechanism in operable communication with the actuatable structure for use in urging the actuatable structure of the electrical switch mechanism from a first position to a second position. An actuatable electrical switch arrangement is also disclosed.
Claims10
A switch actuation device for use in connection with an electrical switch mechanism having an actuatable structure, comprising:
- an actuation mechanism in operable communication with the actuatable structure and configured to urge the actuatable structure of the electrical switch mechanism from a first position to a second position;
- and
- a housing having:
- a base portion with an opening extending therethrough, the base portion configured for rigid attachment to the electrical switch mechanism, and the opening configured to receive the actuatable structure therethrough;
- and a housing portion moveably attached to the base portion;
- wherein the actuation mechanism comprises:
- a fluid chamber having a plurality of areas, wherein, in operation, the plurality of areas are in fluid communication with each other via a valve and a fluid release conduit;
- a plunger having a plunger head and configured to urge fluid from one area to another area through the valve;
- and
- a spring configured to urge the fluid from one area to another area through the release conduit;
- wherein, when the plunger is moved by an urging force, the spring is compressed and the fluid flows between areas via the valve, and when the urging force is removed, the spring expands and the fluid flows back between areas via the fluid release conduit.

An actuatable electrical switch arrangement, comprising:
- an actuatable structure in electrical communication with an electrical wiring system of a structure;
- and
- an actuation mechanism in operable communication with the actuatable structure and configured to urge the actuatable structure of the electrical switch arrangement from a first position to a second position;
- and
- a housing having:
- a base portion with an opening extending therethrough, the base portion configured for rigid attachment to the electrical switch mechanism, and the opening configured to receive the actuatable structure therethrough;
