A switch assembly is provided for connecting a battery to an electronic assembly which is part of a sonobuoy which is deployed from an aircraft. A normally-closed micro-switch is connected in a battery circuit and a rotatable cam depresses a lever arm on the micro-switch to open the circuit. A lanyard, having one end attached to an aircraft, is attached to the rotatable cam and launching of the sonobuoy causes the lanyard to rotate the cam and release the lever arm of the micro-switch. A safe pin prevents rotation of the cam until the safe pin is removed prior to launch.
