Deceleration sensor switch for use in a vehicle occupant safety system
First Claim
1. A deceleration sensor switch comprising:
- a base;
a first electrical terminal mounted on said base;
a first electrically conductive strip connected to said first electrical terminal;
a mass;
support means for pivotably supporting said mass on said base such that said mass can pivot from an unactuated position to an actuated position when said mass is subjected to deceleration of at least a predetermined magnitude, said support means comprising (i) a second electrical terminal mounted on said base and (ii) a second electrically conductive strip interconnecting said second electrical terminal and said mass to enable said mass and said second electrically conductive strip to pivot together about a fixed pivot point located at said second electrical terminal from said unactuated position to said actuated position, said mass being fixedly connected to an end of said second electrically conductive strip;
said second electrically conductive strip being located on only one side of said mass and comprising a spring portion which deflects into electrical contact with said first electrically conductive strip to electrically connect said first and second electrical terminals when said mass and said second electrically conductive strip pivot about said fixed pivot point to said actuated position.

Abstract
A deceleration sensor switch (10) comprises a base (12) and a mass (60) pivotable from an unactuated position to an actuated position when the mass is subjected to deceleration of at least a predetermined magnitude. A first electrically conductive portion (70) is connected to a first electrical terminal (46) mounted on the base (12). A support structure (40) supports the mass (60) on the base (12) to pivot from the unactuated position to the actuated position. The support structure (40) comprises a second electrical terminal (42) mounted on the base (12) and a second electrically conductive portion (50) interconnecting the second electrical terminal (42) and the mass (60). The second electrically conductive portion (50) comprises a spring portion (52) which deflects into electrical contact with the first electrically conductive portion (70) to electrically connect the first and second electrical terminals (46, 42) when the mass (60) pivots to the actuated position.
