摘要 |
<p>An outer arc extinguishing compartment is disposed coaxially with an inner arc extinguishing compartment and partly projects under one end thereof. A movable contact member extends through both compartments and separably engages a stationary contact member located within the inner compartment. A plurality of arc suppressors of spindle-shaped cross section are disposed at equal angular intervals in the projecting portion of the outer compartment adjacent to and about the movable contact member to extend axially and radially of the latter. The circumferential minimum distance between the arc suppressors is smaller than the diameter of a positive column of an electric arc struck across both contact members.</p> |
