Note:

1. Power factor of inductive load is above 0.4 (AC). The time constant is below 7ms (DC).
2. The inrush current of lamp load is 10 times that of steady state current, and the inrush current of motor load is 6 times that of steady state current.

Tips: 4 considerations of limit switches

1. Please do not connect a power source of different polarity or different type to the contact of one limit switch.
2. Please do not apply voltage between contacts during circuit design (may cause contact melting).
3. Even in the event of an abnormal situation, there should be no short circuit (may lead to fusing of conductive parts).
4. Limit switches used in electronic circuits (low voltage and low current).
   1. If the vibration and tremor of the contacts cause problems, please take the following measures.
      1. Insert the integrating circuit.
      2. The pulse caused by vibration and chatter shall be controlled below the disturbance tolerance of the load.
   2. In the fields with particularly high contact reliability requirements, the original silver contacts are not suitable. The performance of limit switches for small voltages and currents with gold contacts is better.
   3. In consideration of safety, Use b for the limit switch for emergency stop.
      To prevent damage to the limit switch caused by a short circuit, connect a momentary fuse with a breaking current value equivalent to 1.5 to 2 times the rated current in series with the switch. When using EN certified ratings, use a 10A fuse gT or gG suitable for IEC60269.
