The Blodgett 21618 Infinite Switch controls electrical heat adjustment in compatible cooking equipment through a variable switching range. Rated at 5 AMP and 120V, this switch uses a 3/16-inch configuration with a horizontal Palnut mount for panel installation. Its control function allows the connected heating circuit to be adjusted according to the selected setting. This component can be used when an existing infinite switch is worn, faulty, or no longer responding correctly. This switch is used in cooking equipment control applications and provides a direct interface for temperature adjustment.
