  • Enclosed Switches with Built-in Basic Switches for High Repeatability and Durability of 10 Million Operations Minimum.
  • Suitable for applications demanding higher mechanical strength, dustproof and drip-proof properties than those on basic switches.
  • Contact Form:

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.
