Abstract

A starter switch arrangement for boats, where the switch may be subjected to water splash or the like. The arrangement includes a key with a gripping component and an insert component to be inserted into an aperture in the switch for opening and locking the switch. The key has a cover component positioned between the gripping and insert components and provided to be sealingly supported against the switch in the inserted position of the key during the utilization of the boat. The cover component will sealing close a portion of the switch around the aperture of the switch.

Claims

1. A starter switch arrangement for environments where a switch may be subject to intrusion of water, such as for a boat or the like during its utilization, said switch arrangement including:

a switch, a key having a gripping component, an insert component to be inserted into an aperture in the switch for opening and locking the switch, and a cover component integrated with and positioned between said gripping component and said insert component, said cover component having a portion which is resilient in axial direction of the key and presents a soft resilient surface generally parallel to and provided to abut against a front surface of the switch in the inserted position of the key, said resilient surface being arranged for sealingly supporting the cover component against the switch in the inserted position of the key and sealingly close at least a major portion of the front surface of the switch around said aperture.

2. An arrangement according to claim 1, wherein the cover component has a collar or flange-like shape and has a comparatively stiff supporting portion, and an elastic portion positioned between the supporting portion and the insert component.

3. An arrangement according to claim 2, wherein the resilient surface, in the inserted position of the key is adapted to sealingly contact a peripheral annular portion protruding from the front surface of the switch.

4. An arrangement according to claim 2, wherein the resilient sealing surface is a surface causing relatively low friction upon engagement with the front surface of the switch.

5. An arrangement according to claim 4, wherein the sealing surface is substantially plane and circular.

6. An arrangement according to claim 2, wherein the supporting portion of the cover component and the gripping component are of one piece, which is symmetric with respect to a tangential and a normal plane of the insert component in axial direction of the key, and which displays a certain degree of flexibility, said cover component and gripping component having radially generally gradually decreasing dimensions in at least said tangential and normal planes in the axial direction away from the insert component of the key.

7. An arrangement according to claim 6, wherein said supporting portion consists of ethylene plastic.

8. An arrangement according to claim 2, wherein the supporting portion is cup shaped and faces the insert component with a concave side and having an annular edge portion to partly enclose the elastic portion.

9. An arrangement according to claim 8, wherein the elastic portion is substantially disc shaped and has a thickness which exceeds the depth of the cup-shaped supporting portion.

10. An arrangement according to claim 8, wherein the sealing surface has substantially the same outer diameter as the annular edge portion of the supporting portion.

11. An arrangement according to claim 2, wherein the cover component forms a floating body for the key.

12. An arrangement according to claim 11, wherein the elastic portion of the cover component forms said floating body.

13. An arrangement according to claim 11, wherein the elastic portion consists of a material with closed cells.

14. An arrangement according to claim 13, wherein said material is foam plastics.
