Welcome to Potter Electric Signal Company! Potter acquired Harrington Signal in 2015 and has continued supporting Harrington products since that time. We have officially retired the old Harrington website and moved all relevant product to this page. Over the past few years all Harrington devices have become obsolete and have been replaced with Potter versions with equivalent, upgraded functionality. Please find all the legacy Harrington product literature in the table below and click on the links above to access all Potter products.
If you have any questions, please feel free to contact us at sales@pottersignal.com or 800-325-3936 and we will be happy to help. Thank you for your patience and we appreciate your support of Potter!
