Abstract

PURPOSE:To decrease the number of parts, such as lock rod or toggle mechanism, and simplify the construction by furnishing a detent part to come in detention on the rotation locus of a lock part so as to hinder the make action of a switch when grounding blades are on. CONSTITUTION:A movable contact piece 7 situated above can contact and separate from the two fixed contact pieces 6 with horizontal rotation of the center insulator 4 of each phase of a breaker 1. A lock plate 44 rotating in regular or reverse direction with opening and closing of this breaker 1 has a detent recess 44b at the periphery 44a. A lock part 48 consisting of a detent step 49a and a detent boss 49b is mating with the lock plate 44 at the top of a rotary rod 17. In the condition that the breaker 1 is on and a grounding device 8 is off, the periphery 44a of the lock plate 44 comes in detention on the rotation locus of the detent boss 49b, when the rod 17 will be hindered from rotation and the two grounding blades 20, 29 can not rise, and thus no grounding can be made. When the breaker 1 is turned off from this condition, the detent boss 49b of the rotary rod 17 comes in mating with the detent recess 44b, and now the rod 17 can rotate and grounding be made.
