ABSTRACT:
A magnetic catch comprises a magnetic assembly and a catch plate. The magnetic assembly includes a magnet flanked by two pole shoes. The magnet and pole shoes are biassed against a casing portion by an abutment feature provided integrally on a support member which is retained by resilient clips extending from the casing. The localized nature of the abutment feature provides a gap between the pole plates and the support member. This gap allows the pole members to move relative to the magnet so that they can align themselves with the catch plate to provide optimal physical contact therewith. Nevertheless, the biasing arrangement holds the magnet in a fixed position which helps to prevent the magnet and pole shoes from rattling.
