Abstract: The invention comprises a signaling device for a soap dispenser. The signalling device is mounted in the housing of the soap dispenser which has a pivotally mounted soap dispensing handle; and when pivotally moving the soap dispensing handle, the movement of the handle causes activation of the signalling device, immediately after dispensing the soap. The signalling device has an electrical circuit with a flexing panel which upon movement of the flexing panel by the engagement of the handle against the panel, it triggers an initial alarm or sound to signal to the operator that the timing interval for the operator to wash his hands with the dispensed soap has begun. The activated circuit thereafter counts a selected interval of time in seconds considered adequate for the operaor to thoroughly wash his hands; and at the end of that interval, the circuit sounds a second alarm or sound indicating that the washing time is over. The circuit then resets itself to repeat the sequence.
