Vehicle latch with interchangeable switch cam lever with lost motion and interchangeable switch cam lever
A vehicle latch assembly, including: a pawl pivotally mounted to the vehicle latch assembly; a claw pivotally mounted to the vehicle latch assembly; a switch cam lever; a first switch; a second switch, the switch cam lever has a first cam profile configured to engage the first switch and a second cam profile configured to engage the second switch, the first cam profile engaging the first switch; and wherein the second cam profile engages the second switch when the vehicle latch assembly is in a secondary position.
1. A vehicle latch assembly, comprising:
a pawl pivotally mounted to the vehicle latch assembly;
a claw pivotally mounted to the vehicle latch assembly for rotation about a first axis;
a switch cam lever rotatably mounted to the vehicle latch assembly for rotation about a second axis, the first axis being parallel to and offset from the second axis;
a first switch;
a second switch, the switch cam lever has a first cam profile configured to engage the first switch and a second cam profile configured to engage the second switch, the first cam profile engaging the first switch when the latch assembly is in an open position; and the second cam profile engages the second switch when the vehicle latch assembly is in a secondary position.
2. The vehicle latch assembly as in claim 1 , wherein the first cam profile engages the first switch when the vehicle latch assembly is in the secondary position.
3. The vehicle latch assembly as in claim 2 , wherein movement of the switch cam lever is facilitated by a post mounted to the claw and the post slides within a slot of the switch cam lever.
4. The vehicle latch assembly as in claim 3 , wherein the slot has a first portion and a second portion, the second portion being angularly orientated with respect to the first portion such that slidably movement of the post in the second portion will cause less movement of the switch cam lever than slidable movement of the slot in the first portion.
5. The vehicle latch assembly as in claim 1 , wherein movement of the switch cam lever is facilitated by a post mounted to the claw and the post slides within a slot of the switch cam lever.
6. The vehicle latch assembly as in claim 5 , wherein the slot has a first portion and a second portion, the second portion being angularly orientated with respect to the first portion such that slidably movement of the post in the second portion will cause less movement of the switch cam lever than slidable movement of the slot in the first portion.
7. The vehicle latch assembly as in claim 1 , wherein the first cam profile does not engage the first switch when the vehicle latch assembly is in the secondary position.
8. The vehicle latch assembly as in claim 7 , wherein movement of the switch cam lever is facilitated by a post mounted to the claw and the post slides within a slot of the switch cam lever.
9. The vehicle latch assembly as in claim 8 , wherein the slot has a first portion and a second portion, the second portion being angularly orientated with respect to the first portion such that slidably movement of the post in the second portion will cause less movement of the switch cam lever than slidable movement of the slot in the first portion.
10. The vehicle latch assembly as in claim 9 , wherein the first cam profile engages the first switch when the vehicle latch assembly is in an open position.
11. The vehicle latch assembly as in claim 1 , wherein the first cam profile engages the first switch when the vehicle latch assembly is in an open position.
12. The vehicle latch assembly as in claim 11 , wherein the first cam profile does not engage the first switch when the vehicle latch assembly is in the secondary position.
13. The vehicle latch assembly as in claim 1 , wherein the first switch is a door open switch and the second switch is a door ajar switch.
14. A method of actuating switches of a vehicle latch assembly, comprising:
pivotally mounting a pawl to the vehicle latch assembly;
pivotally mounting a claw to the vehicle latch assembly for rotation about a first axis;
pivotally mounting a switch cam lever to the vehicle latch assembly for rotation about a second axis, the first axis being parallel to and offset from the second axis;
engaging a first switch with a first cam profile of the switch cam lever and engaging a second switch with a second cam profile as the switch cam lever pivots; and
wherein the second cam profile engages the second switch when the vehicle latch assembly is in a secondary position and movement of the switch cam lever is facilitated by a post mounted to the claw that slides within a slot of the switch cam lever.
15. The method as in claim 14 , wherein the first cam profile engages the first switch when the vehicle latch assembly is in the secondary position.
16. The method as in claim 14 , wherein the slot has a first portion and a second portion, the second portion being angularly orientated with respect to the first portion such that slidably movement of the post in the second portion will cause less movement of the switch cam lever than slidable movement of the slot in the first portion.
17. The method as in claim 14 , wherein the first cam profile engages the first switch when the vehicle latch assembly is in an open position.
18. The method as in claim 14 , wherein the first cam profile does not engage the first switch when the vehicle latch assembly is in the secondary position.
19. The method as in claim 14 , wherein the first switch is a door open switch and the second switch is a door ajar switch.
