    • PROBLEM TO BE SOLVED: To provide a double-break circuit breaker having one pair of contact points and a single-break circuit breaker having one pair of contact points with an operation handle position unified while attaining component standardization of a switching mechanism portion.
      SOLUTION: A housing of the circuit breaker comes either with or without a double-break unit case where movable contacts and stationary contacts form two pairs. Also, a frame fixed to the housing comes with two separate mounting members arranged side by side, that is, a first fixing member to be fixed to a housing equipped with the double-break unit case, and a second fixing member to be fixed to a housing not equipped with the same.

    • PROBLEM TO BE SOLVED: To provide an electromagnetic relay having small size, high performance, high assembling precision, at a low cost, with high productivity and high reliability.
      SOLUTION: Electromagnetic relays consisting of a normally open contact point that closes when exciting current runs through a coil 11 and a normally close contact point that closes when the exciting current is cut are arranged in parallel with each other on a base block 2 so that plurality of normally open and normally close contact points are positioned diagonal to each other and symmetric with respect to a point. An electromagnetic relay block 1 with first and second fixed contact point parts 22 and 23 capable of connecting to each external wiring forming the electromagnetic relay and a movable contact 14b is assembled by using common parts.
