<p>PROBLEM TO BE SOLVED: To provide a limit switch unit, in which there are no detection obstruction of a current circuit and no breakage of the limit switch due to repeating impacts or the like, and a position adjustment in manufacture and at an installation location can be minimized.SOLUTION: A switch attachment plate 22 having a structure that can be fixed at a position other than a lifting part 30 of a high-frequency current disconnector, and a base plate 10 removably installed on the switch attachment plate 22, are provided. Dogs (switch operation members) 2a and 2b are engaged with a supporting shaft 15 bridged between a pair of fixed members 12a and 12b on the base plat 10 to operate a limit switch 18. Due to springs 3a and 3b, deviation between a limit positions of the dogs 2a and 2b and a limit position of the lifting part 30 can be absorbed. An installation position of the base plate 10 on the switch attachment plate 22 is memorized by a positioning member 14a and a positioning pin. The base plate 10 and configuration elements thereon configure a base plate unit.</p> |
