ABSTRACT:
A timer assembly mounted removably on a personal soap dispenser of a type having a pump operated by a soap dispensing plunger with a handle and spout. The timer assembly has a housing capsule with a timer for measuring a preselected time interval; LEDs and a music generating chip for signaling the time interval to the user, and a pressure switch for starting the timer. The housing capsule is received in a flexible hood/cover mounted on the top of the handle so that pressure switch is actuated to start the time by pressure of the user's hand during depression of the handle to dispense soap.
