<p>Both parts of the casing (2, 3) are fixed together by a resilient connection (46). Between the two parts an elastic rubber washer (12) is stuck. This washer (12) is housed into a groove (11) provided into a support (10) to which are fixed the drive motor (9) as well as a printed circuit board (18). A magnetic control switch (19) for starting and stopping the motor, is mounted on this board (18). It is actuated by a magnetic piece (21) fixed to a movable control member (20). The washer (12) dampens the vibrations, prevents the transmission to the casing (1) of vibrations coming from the motor (9) and is used at the same time as a sealing lining. </p> |
