The switch assembly is non-intrusive and maintains water tight integrity inside the casing. The switch assembly futher includes a magnetically operable switch for selectively connecting and disconnecting two pairs of terminals. An R.F. transmitting location marker is also employed using a transmitter circuit and an antenna.
