A quick question for Roger/all regarding my missing hazards if I may thinking

[Linked Image]

I note in addition to being switches, the four above switches are also used as locating dowels for the board itself, and with the whole dreadful sandwich clamped together using the four corresponding plastic twist pins I've circled below:

Now, if we get in close on the back of one of these switches these look like the switch contacts to me.

I wonder if my loss of hazards is simply due to me failing to push the hazard switch home firmly enough, and or I failed to ensure the twist pin wasn't located properly so one of the switch contacts isn't being pulled tightly against its corresponding supply terminal?

Has anyone else suffered such an issue and traced it to poor switch location, or weak PCB to switch clamping force due to a badly engaged twist pin?
