What Is a Magnetic Switch?

A magnetic switch is just like a light switch: it turns a circuit on or off depending on what position the arm of the switch is in. The only difference is that a magnetic switch is operated by a magnet, rather than your fingers.

Parts
A magnetic switch has an arm of conductive metal that is fixed on one end, two switch contacts that are near the free end of the arm, and a movable magnet. Some also have two magnetic clamps.

Types
There are three types of magnetic switch. Normally open monostable switches remain connected only when the movable magnet is near the arm. Normally closed monostable switches remain disconnected only when the magnet is near the arm. switches change position from open to closed whenever the magnet moves, but remain in their last position even when the magnet moves away.

How They Work
When the movable magnet comes close enough to the free end of the arm it attracts the metal arm to it. This brings the end of the arm into contact with (or away from contact with) the switch contacts.  switches have magnetic clamps that hold the arm in place after the magnet moves.

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.

If you’re looking for a versatile electrical switch, then consider using a magnetic switch. We’ve dedicated ourselves to creating some of the most innovative and advanced magnetic switches found today. For more than 25 years, we’ve provided custom magnetically activated switches for our customers, who have come to rely on us for dependable, reliable, quality products at competitive prices.

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
In addition, when you use switches in particular, you can be sure that you will be using some of the highest-quality and longest-lasting switches currently available on the market. Our customization capabilities ensure that you’re getting a magnetic switch that best fits your application.
