Abstract
A waterproof digital lap counter automatically counting and indicating the number of laps traversed by a swimmer having the lap counter attached to a hand or foot comprises a LCD array including a digital counter, driver and LCD embedded within a sealed inner housing which is slidably and nonrotatably supported in an outer housing. Counting and indication of laps traversed occurs automatically and is triggered by abutment of the lap counter against the side of the swimming pool during the swimming stroke or flip turn of the swimmer. Abutment of the lap counter against the side of the pool momentarily closes a switch which sends an input signal to the LCD array representative of a lap traversed. The LCD array counts and provides a visible indication of the number of input signals received which corresponds to the total number of laps traversed.
