- What does actuation and de-actuation mean?
- 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.
- On your Flow Switches, which model has a Form C type contact
- Form C contact is a SPDT snap switch. Many of Dwyer’s flow switches have SPDT snap switches. The V4, V6, V7, FS-2, and V8 are some of them.
