ABSTRACT:
The battery operated signal device employs a gravity operated switching system with a time delay. The time delay is effected in one embodiment by having a weighted element move through a tortuous path when the signal device is thrown into the water before activating the contacts of a switch to energize a circuit. In other embodiments, the time delay is effected by pendular members which pivot when the signal device is inverted to either actuate a switch or to permit passage of a ball to actuate the switch. The time delay extends the time required to turn on the light so that forces developed on the light by the pitching, plunging and rolling action of a vessel do not result in intermittent unwanted operation.
