ABSTRACT:
A plug-in surface heating unit assembly for use in the cooktop of an electric range. The heating unit is a metal sheathed electrical resistance heating element in spiral form with radial, outwardly directed terminal portions in close formation. The invention relates to a folded spring blade which is fastened between a movable terminal block and the cooktop so that the spring normally biases the terminal block into an upward position while biasing the heating unit into a down position so that the unit will sit level with respect to the cooktop. The terminal block is supported by means of a lost-motion connection from a fixed mounting bracket that is supported under the cooktop.
