Hazard switch will not lock - how to fix?
 

Hello everyone! I am a newbie. I have a 1997 Nissan Sentra GXE GA16DE. The Hazard switch will no longer lock or latch. I have to push it in and hold it for the lights to flash.
I took the switch apart and there is a tiny piece of plastic that broke of the mechanism that latches/locks. It works similar to how a spring loaded ballpoint pen locks and unlocks.
Is there a place to buy that tiny plastic piece only? Is there a way to fix or rebuild that plastic piece? Superglue did not work. See attached photos. Thanks in advance for your comments.
