If by switch, you mean swap, no, not really, each different manufacturer makes their PNs to fit their hardware, for example, back when Compact & Tristar vacs used Eureka-type PNs, they had an adaptor to fit the Eureka PN's elbow, without it, the Compact/Tristar wands fit, but will not lock as the button is higher up compared to a Eureka wand...
With some vacs, you can modify a modern replacement hose to take the wands & PN, but it varies from brand to brand and even vac to vac... :)
Comes to the Rescue!
