89 Suburban: correct door jamb switches??

[Electricduane]

Hello: several web sites, including Amazon, indicated to me that this type of door jamb switch (attached) is the correct one for my 89 burb.

I'm pretty much positive this is incorrect. When I installed it and carefully began to close the door, I saw that it is not correct. At least I believe it is incorrect. The spring/ plunger thing does not travel far enough. In other words, if I were to slam the door on it, I'm pretty sure it would simply punch through the inner edge metal of the door frame. It looks to me like the plunger/spring thing should be able to move/compress farther, such that when the door closes it would be nearly flush with the silver nut portion of the switch mechanism. The black tubing doesn't really help that problem.

I assume this must be the correct door jamb switch for a later generation(s) of Suburbans.

I would appreciate any advice or input on this subject, especially part numbers for the correct door jamb switches. It's a minor but kind of annoying thing that my lights don't come on when I open the doors. It's especially annoying that something like this that should be so simple becomes complicated when websites/companies that should know better send you the wrong part. Thanks!
