A magnetic door catch (10, 20), for a door (100) and frame (301) assembly of an oven, has a first magnetic member (10) slidable in a housing (102), on the door (100), against resistance supplied by a leaf spring (204). The member (10) has opposed pole pieces (12, 13) to attract a striking plate (20) on the frame (301). The pole pieces (12, 13) are dimensioned so that there is substantially no variation in the magnetic force between the member (10) and the plate (20) with change in temperature of the oven. The plate (20) is resiliently mounted on rods (302,303) by helical-coiled springs (S, S.) Alternatively, the housing (102) may be resiliently mounted. |
