If you want oscilloscope waveform data and screenshots, you can get them in the engineering attachments.

### Project Description

H1 and H2 default to **high level** output when the buttons are not pressed; H3 and H4 default to **low level** output when the buttons are not pressed.

The output high level is 5V.

### Notes
- When purchasing, please note that the resistor is a small resistor with a power of 1/8W (uh, I didn't notice it on the drawing board).
- Pay attention to the direction of the normally closed contacts of the lockless switch when welding.
