Abstract
A cap for use in making a hermetically sealed switch is made by depositing a layer of a compound of chromium and iron on a core, in an ammoniacal atmosphere and subsequently removing the core by chemical means. The core may be made of thin steel so that it can be dissolved by acid treatment.
