Transfer switch question

[budhiman]

Is there a REVERSE transfer switch? I have seen a transfer switch that switches a load between two sources. Is there an application or product which operates opposite to a typical transfer - switch between loads instead of sources (A single source with the option to feed a small ampere load vs a high ampere load)?

Manually operated double throw switches are commonly available.

There are automatic switches available which are intended to allow a clothes dryer and an EV charger to share a circuit, or to allow two EV chargers to share a circuit.
