Notice of Discontinued Product and Model Changeof Vacuum Switches

Thank you for using CANON ANELVA products.
We discontinued the sales of the vacuum switch 954-7730 (heat-resistant specification) on March 31,
2016 and has no succeeding model.
Regarding the vacuum switches 954-7700 (ICF specification) and 954-7720 ( 15 gauge portspecification), the model names are changed along with the modification of internal components (i.e.
bellows).

We concluded that, although the pressure specification varies, the modification has little

impact on the usage.
For comparison of the existing models, 954-7700 (ICF specification) and 954-7720 ( 15 gauge portspecification), and the succeeding models, refer to the attached sheet. The succeeding models havestarted selling on April 2016.
We apologize for a late reply.
We will continually improve the product quality and reliability to ensure customer satisfaction.
