This guide is designed to assist you in comparing our products with those of notable competitors Tecmark and Herga. Click here to learn more about our line of Magictrol air switches.

Presair Magictrol Air Switches are used to sequentially switch up to four separate pieces of equipment. Each time an air pulse is applied, a stepping cam is rotated through three or four positions, actuating a combination of two or three microswitches. Magictrol switches can be used up to 15 feet away from actuator or foot pedal. Distances of 100 feet away can be reached with solenoid and momentary air switch.

Competitors such as Tecmark and Herga offer distinct series of sequencing air switches, engineered for specific applications. This article focuses on Tecmark’s CSC and SAS-100 series as well as Herga’s 6806 and 6872-AC series. If you currently utilize one of these series and are exploring alternatives or seeking a precise cross-reference, this guide is tailored to you. Whether you’re an experienced technical professional or navigating the technical details of sequencing air switches, our cross-reference guide is designed to streamline your decision-making process, ensuring a precise match for your specific technical requirements.
