MAGNETICALLY COUPLED CONTROL FOR APPLIANCE

摘要

A magnetically coupled control arrangement especially adapted for an appliance, such as a cooking device subject to being dirtied from cooking spills, has a user-operated control member knob with multiple alternating magnetic poles on its underside adapted to be placed against a control area on a substantially non-magnetic sheet to register with a following member, having multiple alternating magnetic poles complementary to the poles of the control members, in the space underlying the control area, with the follower member being linked to adjustable means for controlling the operation to be carried out, such as the cooking operation. The arrangement is such that the user-operated control member may be removed completely from the control area to facilitate cleaning that part of the device.
