Abstract

The present invention discloses a limit switch and a circuit breaker including a contact member driving portion and a switch portion. The contact member driving portion has a rotation shaft portion connected to a contact member and rotates in conjunction with the contact member so as to be connected to or disconnected from an electrode stem; a switch portion fixedly arranged on a body and spaced apart from the contact member driving portion, the switch portion having a plurality of switches for transmitting to the outside signals relating to the connection or the disconnection when the connection or the disconnection is performed; and an on-off operation unit which is driven in conjunction with the rotation shaft portion and which is capable of simultaneously activating or stopping the plurality of switches when the contact member is connected to or disconnected from the electrode stem.

Description

technical field [0001] The invention relates to a limit switch and a circuit breaker provided with the limit switch. Background technique [0002] Generally, a circuit breaker is a power device used in industry, which can automatically cut off the line when an accident current such as an overload current or a short-circuit current occurs on a relatively low-voltage transmission and distribution line. [0003] A circuit breaker generally performs a making action for closing an energized circuit and cut-off action for disconnecting energized lines. The closing and breaking actions of such a circuit breaker are generally performed automatically or by user's selection according to the state of the energized line. [0004] In addition, a plurality of switches are provided on the circuit breaker, and the switches can transmit a signal about on or off to a display unit, a control unit, etc. when realizing the above-mentioned on operation or off operation. Furthermore, it is nec...
