The present invention relates to a durability test device for a lever switch for an automobile, and in particular, to turn on a direction indicator light of a vehicle, or to have various functions such as other wiper liquid injection, switching of up and down lights or lighting them, window brush driving, and the like. The present invention relates to an apparatus for testing the durability of a lever switch for a vehicle used to test the repeated durability of a mechanical contact of a direction switch lever switch having a direction or an angle of operation.

Conventionally, in order to test the durability of a lever switch for a vehicle, it is necessary to give a movement necessary for returning to a neutral position in parallel with a vertical movement with a relatively high frequency of use. Since the contact state is tested using a simple test mechanism (for example, a slider paired with a single pneumatic cylinder) by giving only two positionings to the lever switch, the other contact points remain untested, resulting in inaccurate test results. There was a problem that was brought, because the slider of the simple test mechanism is configured to slide, the friction is severe, so a lot of power loss occurs, and because the size of the simple test mechanism is relatively large, there was also a problem that occupies a large installation space.
