What Is a Magnetic Latch?
Magnetic latches are devices used to switch or toggle states using magnetism.
These latches operate with mechanisms powered by magnets, enabling the switching of states or locking into specific positions through the arrangement of magnets or changes in magnetic fields. They are particularly useful in situations where mechanical operation without electricity is desirable, or where electrical interference needs to be avoided. Common applications include sensing doors or windows, security systems, and operating the opening and closing of automobile trunks or hoods.
Leveraging the polarity of magnets to alter magnetic fields, magnetic latches can move mechanical components and toggle switches on or off. They can be controlled using either permanent magnets or electromagnets.
