Vintage Honeywell Micro Switch compared to a contemporary Honeywell Micro Switch. Both are 1SX1-T models.
The vintage is from The 24th week of 1974 and the contemporary one is from the 26th week of 2007.
Notice the thickness of the word “MICRO” on the vintage Micro Switch when compared to the GMH Micro Switch.
