Features：
　These foot switches are designed for critical applications such press brake machine control. The safety pedal has three positions with a pressure point to control hazardous movement. Four working contacts (2NC+2NO) handle normal operation and one safety switch (1 positive opening NC contact + 1NO) provides emergency stop control.

---

For example, when normal force is applied, the working contacts switch and the press moves downward. Additional force beyond the pressure point will cause the working contacts to return to their initial position and activate the positive opening safety contact. This redundant safety circuit will prevent any further hazardous movement.
