Unknown Swiss Military Pin

[Johnny41]

I acquired this pin a number of years ago at a second-hand store, and have been able to find very little information on it. There is a similar pin listed here: https://www.militariadefoerier.com/a-21653085/swiss-zwitsers-militaria/swiss-badge-zwitsers-speldje-embleem-defile-1e-divisie-1937/ , but there is no information about them. Has anyone here ever seen one of these before, and have any information about them?

Thanks!
