Superior performance with magnetically-actuated switching design
Increased product life due to free-swinging vane, which attracts a magnet within the solid metal switch body to actuate a snap switch by means of a simple lever arm with no bellows, springs, or seals to fail
Meets application requirements with durable leak proof body machined from bar stock
Long operating life with robust vane design which is rigid and field trimmable for set point adjustment

Questions

Question

What does actuation and de-actuation mean?

Answer

Actuation means that the flow rate has reached a point where the microswitch trips or the contacts of the microswitch change state. De-actuation means that the flow rate has decreased to a point where the microswitch returns to its normal state.
