Magnetic Switch Installation in Beaumont & Port Arthur, TX

A magnetic switch is an electrical switch that makes or breaks contacts in the presence of a magnetic field. The switch remains actuated as long as a strong magnetic field is present and opens when the field is removed. Examples of magnetic switches are reed switches, hall effect sensors, and electromechanical relays.

The specialized design of magnetic switches involves the use of a movable magnet that is “seen” by the switch. When the magnetic field is detected by the switch, it activates the switch contacts, either turning the electrical circuit “on” or “off,” depending on the switch configuration. The switch can be either exposed to view or concealed by a piece of equipment when installed, thus making it more difficult to defeat.

Lever arm, or other mechanical style switches, are more prone to failure of external moving parts or being more easily overridden. Magnetic switches are not affected by oil, water, dirt, dust, ice, and are less likely to be defeated.

Benefits of Magnetic Switches

No matter the type you choose, using magnetic switches over other kinds of electrical switches offers some unique advantages. These advantages include:

• Switch on/off quickly
• Less contact resistance
• Longer lifespan
• Lower maintenance costs/requirements
• More difficult to override
