CH4x4 switch not engaging?

I just received a mini toyota style button from CH4x4 and it seems to only engage when I put some pressure on the rear of the button where the wiring harness plugs in. If I don't push on the rear to keep the inner and outer housings flush, pushing the button results in pushing the inner housing slightly out the back of the outer housing and nothing engages. It's like the button wasn't assembled correctly. I didn't wire it up to anything yet, but I can tell when it does and doesn't engage by the audible click and when the button face locks in. I've already contacted ch4x4 about this, but in the meantime, has anyone else had a similar experience? I expected more from a place that charges out the nose for buttons, but I'm also Mr. lemon, so this is kind of par for the course for me.

Notice the rear is flush or slightly inset:

Notice the rear is sticking out slightly:

 

Just incase anybody runs into the same issue, ch4x4 ended up sending out another switch. In the meantime however, I pushed the inner piece in flush with the outer then used a soldering iron to melt the plastic together a little. Now the inside doesn't slide around and the switch works as it should.
