Power switch on my little Fosi amplifier broke. I’m trying to find a replacement of this little switch and not finding anything. This switch is labeled MHao MS-102 2A/250v or 5A/125v. ![20231025_200907](https://global.discourse-cdn.com/digikey/original/3X/e/9/e9c472822daf1dbe4e24334973538d7648e0f5f2.jpeg) ![20230919_123045](https://global.discourse-cdn.com/digikey/original/3X/c/2/c23dadbb0621c3a13547516bfd361c5b0606f66c.jpeg) ---

Hello, Thanks for the photos. Take a look at Digikey part [100SP1T1B1M7QE-ND](https://www.digikey.com/en/products/detail/e-switch/100SP1T1B1M7QE/3777877) as a possible option. You’ll want to verify the dimensions to be sure it will fit from the [datasheet](https://e-switch.com/wp-content/uploads/2022/06/100.pdf) on page 117. ---
