| PROBLEM TO BE SOLVED: To reduce the number of parts items to improve operability, and realize miniaturization, by applying the constitution that when an electric current more than a fixed value, flows in a bimetel, the connection between a reset member and a cross bar member is released and by manually moving the reset member against a contact pressure spring the reset member is engaged and connected again with the crossbar member to return the reset member to an ON condition. SOLUTION: In bimetals 18 and 18', one side is electrically connected to movable contact plates 6 and 6' by a rivet or welding, etc., and also another side is connected to load side terminals 8 and 8' by lead wires 7 and 7'. When an electric current flows in the bimetals, the bimetals are bent due to self-heating; and when the electric current becomes a specified value or more, an acting member 12 is rotated in a direction, where the engaging part 1201 of an acting member 12 is disengaged from a crossbar member 13, with an axis 11 as the center via adjusting screws 19 and 19'. By manually pushing a reset button 9 downward a reset pivotally supporting part 10 and the pivotally supported acting member 12 are moved downward, to be in a contact-ON condition by the engagement of an engaging step part.

| PROBLEM TO BE SOLVED: To provide a switch mechanism for separating a contact set when an insufficient voltage condition is caused. SOLUTION: A level assembly 3 is included in this mechanism, and is pressed by a spring 9 to be pivotedly driven around any of two fulcrums 4 and 8 to close or separate a contact respectively. Only one side fulcrum position is related to one time movement of a lever assembly body 3, and the movements around one side and the other side fulcrum positions 4 and 8 close a contact set and separate a contact respectively. Insufficient voltage releases the retaining a plunger 7 by a solenoid 6 to commence action around the fixed fulcrum 8. The action of a reset button 10 by manual operation commences action around the movable fulcrum 4 when voltage is sufficient. An arm 5 is displaced by the plunger to shift the movable fulcrum, also returns the plunger at the time of resetting. The switch mechanism can be assembled into a current control device forming insufficient voltage by detecting electric defectiveness. | ||||||
