Handheld shower head sets for handicapped people

Question: I'm am looking for a handheld shower head/hose system with an on/off control at the hand hold area.  I need it for a handicapped person.  Do you carry one that fits my needs?

The Ondine Classic Range is great for this purpose and has been used in hospitals and other healthcare areas because of the easily accessible thumb-control switch on the back. Check these products:
