Claims

[Scope of utility model registration request]

A handle rotatably supported on the breaker housing, an energy storage spring that accumulates pressure when the handle is operated, and a contact opening/closing mechanism side disposed within the housing and the energy storage spring side are connected. a link mechanism that prevents the link mechanism from driving the contact opening mechanism to close when the accumulation of pressure in the energy storage spring is completed; an ON operation body that releases the contact to close the contact, and a contact open standby maintenance mechanism that prevents the link mechanism from driving the contact opening/closing mechanism to open by the spring force of the contact pressure spring in the opening/closing mechanism when the contact is closed. an OFF operation body that opens the contact by canceling the contact open standby state caused by the contact open standby maintenance mechanism; the ON and OFF operation bodies are juxtaposed on the front surface of the housing; The D-type switch of the contact closed standby maintenance mechanism that is driven and the D-type switch of the contact open standby maintenance mechanism that is driven by the OFF operation body are moved approximately from the front side of the housing to the rear side. - an air breaker located near the front surface at a distance;
