Hence, labor for the test is eliminated to shorten time. Also, a rush current wave form obtained by the contact type electro-magnetic switch is akin to the rush current wave form applied to the apparatus under the practical use condition, and the respective wave forms in the repetitive application are fixed.  Thus, the test with far more satisfactory reproductive property is performed in comparison with a manual test by using the contact type electro- magnetic switch.
