ABSTRACT:
A hygienic device comprising an a.c. oscillating motor which has a fixed oscillation rate dependent on the a.c. supply frequency. The amplitude of the oscillations or torque of the motor is varied by varying the power supplied to the motor. The amplitude or torque may be varied in discrete steps by switching different resistors in series with the motor. Reed switches are used to switch the resistors and are mounted obliquely, to facilitate assembly and to reduce the danger of electric shocks to the user.
