Abstract: A substantially sealed and pressure compensated electrical package including a limp bladder in fluid communication with a module having electrical switching elements, the bladder being capable of substantially stress free inflation and deflation in response to changes in external environment pressures, without any fluid exchange between the module and the environment, whereby protection against toxic atmospheres is provided and inadvertent switching due to environmental pressure changes is avoided.
