Presair’s Sequencing Air Switches are three or four function air actuated sequencing switches designed to control the sequential operation of multiple electrical devices such as a pump, blower, lights, or motors. Available both mechanical or solenoid powered, the sequencing air switch features a unique cam and rachet mechanism enables users to select a desired function from remote distances.
The Magictrol Sequencing Air Switch allows you to switch up to four separate pieces of equipment in sequence, alternate action. Each time an air pulse is applied, a stepping cam is rotated through three or four positions, actuating a combination of two or three micro switches. For long distances, available with solenoid operation.
