Switch Action Principle
The disc contact consists of two separate conductive dome diaphragms separated by an insulating material. Under pressure, the upper diaphragm collapses suddenly to establish contact with the lower diaphragm, ensuring reliable tactile feedback and self-cleaning operation.

I'm particularly impressed with how carefully the header pins are packed for the RP2350-PiZero, they arrived in perfect condition without any bent pins, which has been a persistent issue with other competitors. This attention to packaging detail really stands out.
I also received the latest A4 revision of the RP2350, which shows you maintain current inventory, that's really valuable for customers who want the most up to date components.
The delivery was quick and hassle free throughout. I'll definitely be recommending you to others!
App feedback: The discounts offered through the app are a nice bonus, but the component search function could be improved to match the ease of use on the website version. The rest of the app functions work well.
