Abstract
An apparatus and method of counting dispensing events or washes in a fluid dispenser in which an activator is moved from a starting position to a dispensing position and back to dispense material includes a counter which is indexable to record a dispensing event and which can only be indexed again after dispensing pressure is totally relieved from the activator for a predetermined period of time. The counter is activated by a switch carried on the activator that initiates a timer when the activator leaves the dispensing position. The timer is reset if the activator is returned to the dispensing position prior to the predetermined period of time elapsing. Only after elapse of this period of time can the counter be activated again.
