Hi,

I think "choke switch" is related to automotives.

It is a manual "switch" that will pull the choke lever inside the carburetor. You will see this in old motorcycles.

If you push the "choke switch" it closes the butterfly valve that blocks the "venturi" of a carburetor. By doing so, you change the mixture between air and fuel to more fuel - overdoing it will flood the motor with fuel and kills the engine.

There are electric version of "choke switch" nowadays.

Regards,

Dandy

Dandy gave an interesting answer. But there is another way to use the term choke switch. In the book End To End QOS Network Design Tim Szigeti and Christina Hattingh use the term to describe a situation in which a switch limits (or chokes) the amount of traffic being sent to a device. Their example discusses a remote branch office with multiple users connected through a switch to the branch router. If the switch to router connection is Gig Ethernet then if something happens in the branch the switch will be able to send so much traffic to the router that it may become overwhelmed. But if the switch to router connection is 100 Mbps then the router is better protected since the traffic will be choked off at 100 Mbps.
