The power-off button, power-on button, indicator light, PE pin, and power-on pins are all connected to the wiring assembly inside the housing. This utility model achieves safe start-stop control. Pressing down the power-on button drives the slider to rise, causing the conductive spring to contact the power-on terminal and energize it. Pressing down the power-off button causes its lower wedge-shaped block to push the locking piece to release the power-on button. The power-on button resets under the action of a third spring, de-energizing it. This double-button mechanism avoids accidental operation, ensuring that power is only connected under clear instructions, improving safety.
