Buying advice

When choosing a magnetic switch consider the required current rating, operating temperature, and whether a contact (reed) or contactless (Hall-effect) solution best fits your design. Reed switches are inexpensive and reliable for low-current applications, while Hall-effect devices provide longer life and faster response but need proper magnet placement. Check the sealing class if the device will face moisture or harsh environments.
