Abstract
An emergency vessel or vehicle location system (EVLS) is provided with a protected mayday switch for controlling the transceiver or module to which it is attached, so as to permit activation of the emergency vessel location system by use of a switch, in one embodiment, on the same microphone used for two-way communication. The protection of the mayday switch is provided by a specialized transparent latch in which the latch is spring loaded over the mayday switch such that accidental depression of the mayday switch is prevented, while permitting viewing of the switch legend through the transparent latch. The protected switch may be used on the microphone, on an auxiliary unit, or on the transceiver itself.
