Detecting switch

A connector with breaking of current for leak useful to implementation to a printed circuit board which is incorporated into a variety of electric appliances. It comprises a connection part for connecting a source and a load, a leak current detection sensor generally in a ring form which receives an extension of the connection part, a breaker part for breaking current between the source and the load in response to a leak detection, an assembly box which stores the leak detection sensor and the breaker part, and the leak detection part is fitted under the assembly box. The breaker part includes a coil to be excited in response to a leak current by the leak current detection part, and an actuator to displace in response to excitement of the coil. Therein the connection part includes a pair of movable strips and a pair of stationary strips each contactable to one of the movable strips, and either of the paired movable strips or the paired stationary strips, or one movable strip and one stationary strip other than contactable to the one movable strip are extended to run through the leak detection sensor, and the movable strips disconnect from the stationary ones in response to displacement of the actuator.
