Abstract
Abstract A switch is provided which is shielded against the passage of electromagnetic energy and is composed of a switch case, a switch lever in the switch case and a flexible electromagnetic radiation shielding boot attached to said case and encasing and shielding the switch lever to prevent escape of electromagnetic radiation through said switch. The boot has a resilient electrically insulating outside jacket and an electrically conductive wire mesh inside lining fitting within the jacket and over the lever.
