Impact switch
First Claim
Patent Images
1. An impact switch, comprising:
- a first member having a reservoir for holding a conductive fluid; and
a second member coupled to the first member over an opening of the reservoir, the second member having a split etch pad forming first and second disconnected conductive portions; and
wherein, responsive to receiving a predetermined level of impact, at least a portion of the conductive exits the reservoir and conductively connects the first conductive portion with the second conductive portion.

Abstract
An impact switch includes a first member having a reservoir for holding a conductive fluid and a second member having a first conductive portion disconnected from a second conductive portion. The second member is coupled to the first member over the reservoir. Responsive to receiving a predetermined level of impact, the conductive fluid moves from the reservoir to an interface between the first and second members to conductively connect the first conductive portion with the second conductive portion.

8. An impact switch, comprising:
-
a first member having a reservoir for holding a conductive fluid; and a second member having a first conductive trace disconnected from a second conductive trace, the second member coupled to the first member; and wherein, responsive to receiving a predetermined level of impact, at least a portion of the conductive fluid migrates around a periphery of an opening of the reservoir to conductively connect the first conductive trace with the second conductive trace. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An impact switch, comprising:
-
an insert having a reservoir for holding a conductive fluid, the reservoir sized to retain the conductive fluid in the reservoir until a predetermined level of impact is received by the impact switch; and an electronic assembly disposed over an opening of the reservoir, the electronic assembly having a first conductive portion and a second conductive portion, the first and second conductive portions disconnected from each other in a non-activated state of the impact switch; and wherein, responsive to receiving the predetermined level of impact, the conductive fluid moves from the reservoir to an interface between the insert and the electronic assembly and migrates along a periphery of the opening to conductively connect the first conductive portion with the second conductive portion in an activated state. - View Dependent Claims (16, 17, 18, 19, 20)
