Abstract: Input force transmitted from a monitored process variable is applied against a displaceable double beam mechanism being opposed by a dual spring bias presettable individually to the separate set points of the switch. Comprising the double beam mechanism is an equalizer beam underlying a pair of scissor beams such that displacement force incurred by the equalizer beam is conducted through the scissor beams and supported push rods to operate the switch actuators. In a hi/lo set point embodiment two switches are separately actuated in a predetermined sequence while in a deadband embodiment a single switch is independently settable for make and break.
