Please note:

This issue is for a particular instance of a switch/button of the original poster. If someone else wants to test the same switch model, they should create a new issue.
The original poster can add additional test sessions to this issue (if they wish) by adding a comment.

Switch Info

Property	Description
Type	push button
Circuit	SPST
Function	Off-Mom (Normally Open)
Model info/markings	JUDCO 1024-2
Voltage & Current rating	14 V 2A ?

Product URL: Original discontinued by manufacturer. This looks like replacement. Digikey replacement forum topic.

How new is the switch? First time used in 8+ years. I think I originally got this from digikey a long time ago.

How do you like the switch? TERRIBLE FEEL! I'm not a button expert, but this has to be the least enjoyable button I've ever used. I can only hope that it isn't meant to be directly pressed. It probably is supposed to have some other mechanism in front of it. It barely moves (<1 mm?), makes no sound and I think I'll stop there before I get mad at a button... 😡
