unit (10) integral with a shower rose (18) and is primarily characterized by the successful
use of a "bare" element (22) for heating the water and by the novel switching arrangment,
comprising a first set of contact points (28) mounted through a flexible diaphragm
(32), the diaphragm forming the roof of the heating chamber (20), and a second set
of contacts (36) aligned so as to engage the first contacts (28) when same are moved
