Testing SPST Momentary Push-Button Switches with Built-in LEDs Using a CD4069 Latching Circuit
A brief technical note about testing SPST momentary push-button switches with built-in LEDs. The author sourced the switches from AliExpress and used a CD4069 inverter-based latching circuit to demonstrate toggling the LED on and off. The post includes a quick demo video and notes about the switch specifications and purchase details.
