Automotive combination switch
View Patent ↗An automotive combination switch includes a housing having an opening through which a steering shaft passes, and a stork switch having a switch box, that is inserted and mounted in the housing and a manipulating rod protruding from the switching box. Snaps protruding from the outsides of walls of the switching box are snap-fitted into locking holes formed on walls of the housing. A claw of each snap is in elastical contact with a periphery of each locking hole by providing an elastic plate in the housing, and elastically contacting the elastic plate to a front of the switch box in the inserting direction.
1. An automotive combination switch comprising:
a housing having an opening through which a steering shaft passes, the housing being fixed to a stator of a car body;
a switch box configured to be received within the housing;
a stork switch having a manipulating rod extending from the switch box;
a plurality of snaps protruding from an exterior portion of the switch box, each snap having a claw portion-configured to snap-fit into locking holes formed in walls of the housing;
an elastic plate disposed in the housing; and
wherein when the switch box is snap-fitted into the housing, a front portion of the switch box contacts the elastic plate and is urged against the elastic plate to provide a biasing force against the switch box in a direction opposite to a direction of insertion so that each claw portion is urged against a periphery of each locking hole to releasably retain the switch box in the housing.
2. The automotive combination switch according to claim 1 , wherein the snaps are formed on the outsides of a pair of substantially parallel walls of the switch box.
3. The automotive combination switch according to claim 2 , wherein a recess is formed at the front portion of the switch box and is configured to receive the elastic plate.
4. The automotive combination switch according to claim 1 , wherein a recess is formed at the front portion of the switch box and is configured to receive the elastic plate.
5. An automotive combination switch according to claim 1 , wherein the snaps are snap-fitted into locking holes by laterally inserting the switch box into the housing.
6. The automotive combination according to claim 1 , wherein the locking holes are formed on a pair of substantially parallel walls of the housing.
7. The automotive combination switch according to claim 1 , wherein the elastic plate includes an urging member configured to contact the front portion of the switch box.
8. The automotive combination switch according to claim 7 , wherein when the switch box is inserted into a receiving portion of the housing by a predetermined distance, the urging member of the elastic plate contacts the front portion of the switch box and elastically deforms creating a biasing force against the switch box in a direction opposite the insertion direction.
9. The automotive combination switch according to claim 8 , wherein the urging member of the elastic plate contacts the switch box at height near a centerline of the switch box.
10. The automotive combination switch according to claim 8 , wherein the front portion of the switch box has a curved face which follows a contour of the urging member.
11. The automotive combination switch according to claim 7 , wherein the urging member of the elastic plate contacts the switch box at height near a centerline of the switch box.
12. The automotive combination switch according to claim 7 , wherein the urging member is curved.
