Vesco traces its roots to 1996, when former Joslyn Hi-Voltage engineer Cecil R. Wristen founded Vacuum Electric Switch Co. in response to design improvements he saw in high-voltage vacuum technology. Now owned by former Joslyn executives and technical staff, the Mogadore company builds on that engineering heritage through vacuum switchgear and controls for electric utilities, steelmaking, and renewable-energy applications, while also supporting equipment in the field.
