PURPOSE:To compensate the complete non-contact of a contactor due to the displacement of the position of a check terminal caused by the dimensional error of a thyristor module itself by providing an error microswitch. CONSTITUTION:An error microswitch 19 is provided at the other end of a lifter 8, and an error microswitch 22 is provided above the lifter 8. In this manner, the non-contact of a contactor 1 due to the displacement of the position of a check terminal 11 caused by the dimensional error of the thyristor module 4 itself can be compensated, and the contactor 10 of the check sensor and the check terminal 11 of the thyristor module are decreased. |
