Spas Heater Flow Switch W/Tee, 6560-857

Can I use this switch with my reverse osmosis system uv part to switch it off when there is no water flow? also what is the size of inlet and outlet.

Do the wire posts have the cover to click back into the hot tub?

Will this work on the Laguna model?

What size are threads of switch. not looking to change fitting just switch. replacing a Jacuzzi # q-12ds10
