1A 250V AC SPST Normal Open(NO) Momentary Switch 2 Pin Mini Micro Push Button Red Cap 20 Pieces

These are great little push button switches. These are normally open (NO) until pressed and held where they then make contact. They do not continue to make contact once you remove your finger from them. There is a washer and a nut for every one of the switches.

Super compact switch that is built well and easy to install in most electronic projects. I used it to convert a mechanical switch over to electric and I cannot be happier with how well it has lasted. Great value for the money.

Contact is not reliable. Poor quality control. Often must push multiple times to get a contact. I do not recommend

These buttons are terribly designed, stay away. I installed one in a system where we're tracking button clicks, less than 200 clicks later and the button is already failing. Save your money and buy something else. And just because this cost me a day of data collection. I've attached some pictures of why its such a piece of junk. The momentary connection is made by a tiny washer at the end of the button plunger. A cheap rubber o-ring tries to keep it off of the top of the "contacts" that are just the tops of the external solder connections. You'd better hope everything is nice and even in there and that the o-ring doesn't rub off parts or move to block the connection like mine did. It's no wonder there are so many reviews of it failing. This is the least reliable electronic part I've ever purchased.

Used for "line locks" on my 52....
