The History of Magnetic Contacts










1930's

reed-switch-comparisonThe REED SWITCH was invented by Bell Telephone Laboratories for telecommunications applications. This switch would later become adopted for use in physical perimeter security systems to detect unauthorized access through doors and windows.

1970's

BMS+3-reed-switchesThe balanced magnetic REED SWITCH contact (BMS) is invented to overcome the single REED SWITCH magnetic contact security vulnerabilities. Unlike single REED SWITCH magnetic contacts, BMS contacts were designed to be resistant to external magnetic defeat attempts which enabled an intruder to evade detection.

1991

UL-light-blue-200x200 The Department of Defense approves Underwriters Laboratories UL-634 safety standard for connectors and switches used with burglar alarm systems. One key specification states – magnetic contact switches shall have a magnetic field with a high probability of alarm if an external magnet is introduced in defeat attempts.

2007

UL-light-blue-200x200Underwriters Laboratories creates a new UL-634 Level 2 high security standard to help SCIF's and other high security installations identify sensors that provide the absolute highest level of intrusion detection. More stringent requirements for this new standard include EXTERNAL and INTERNAL resistance to magnetic defeat tampering. Magnetic contacts that do not meet these new requirements will remain as UL-634 LEVEL 1 standard devices.

Did You Know?

When World War I ended, an increase in crime followed. As a result, Americans became sensitive to security needs and were eager to find ways to protect themselves and their property. Additionally, many insurance companies began offering premium discounts to alarm subscribers. These events produced a consumer demand for alarm systems.

The first home security systems

During this time, homeowners may have subscribed to a service called door shakers— a group of night watchmen who would shake subscribers’ doors each night to ensure they were locked. More advanced users may have installed an alarm system that used electromagnetic contacts fastened to doors and windows, which were connected to a battery and bell. These systems were monitored by a central station that sent a guard to the residence when the alarm was triggered.
