NOTES: 1. Inductive load has a power factor of 0.4 min.(AC) and a time constant of 7 msec.max.(DC).
2. Lamp load has an inrush current of 10 times the steady-state current
3. while motor load has an inrush current of 6 times the steady-state current.
4. Product with spring, its usable range of operating part is within one third of the whole
spring length from the front end of spring.
