INVENTION: The Reed Switch

Reed vs. MAGNASPHERE

INVENTED IN THE 1930’s by Bell Labs for telecommunication applications, the reed switch has since been adapted for use in security systems to detect unauthorized access through doors and windows.  Despite its widespread acceptance, the reed switch contact’s easily exploitable operational flaw and constructional weaknesses undermine its ability to effectively act as a security system’s first line of defense, compromising the integrity of the entire intrusion detection system.
