Magnetic Reed Switches can be customized for your design needs. Some customization includes sorting specific magnetic sensitivity pull-in ranges and cutting and/or bending the Reed contact leads for either horizontal or vertical surface mount applications or other special mounting requirements. Proper handling and manufacturing technique as well as specialized equipment are essential to producing high quality Reed Products.
