| 150 | Slide switch with externally mounted protective circuit breaker | US936081 | 1986-11-28 | US4764745A | 1988-08-16 | Tatsuo Aoi; Yasuhiro Kiyono; Sueaki Honda; Hauro Atsumi |
| In this construction there are provided: a case; several contact members exposed within the case; several lead terminals electrically connected to some of the contact members, and a support member, all insert molded in the case and protruding outwards; and a circuit breaker provided outside the case, one of its ends supported by a lead terminal and its other end supported by the support member. Thereby compact and efficient unitary construction are attained, and space within a device to which this construction is to be fitted, can be economized. The contact members may be five in number, and may be arranged within the case for contact in a linear relationship, alternatingly serving as input side and output side contact members, with the end ones and the middle one serving for being switched between while the other two serve as common contact members. In this case, the two end contact members should be electrically connected together, and the construction may further include a pair of contact members which slidingly move, in synchronization, over the common contact members and their neighboring contacts. Alternatively, the construction may further include a movable contact member mounted slidably over the contact members with one of its surfaces confronting a surface of a slidable impeller member, one of these surfaces being formed with a hemispherical protuberance and the other being formed with a hemispherical depression cooperating therewith, thus coupling together these members. | ||||||
| 151 | Circuit breaker with electrical and mechanical trip indication | US38470273 | 1973-08-01 | US3863042A | 1975-01-28 | NICOL RONALD |
| A circuit breaker having a handle stop for restraining the handle in a ''''tripped'''' or central position after the circuit breaker is electrically tripped to mechanically and visually indicate the tripped position. Also, an actuator is supported within the case of the circuit breaker and pivoted by the linkage mechanism (only when the latter is electrically tripped). During manual opening and closing of the circuit breaker contacts, the linkage mechanism does not pivot the actuator. Pivoting of the actuator (upon electrical tripping of the linkage mechanism) causes the actuator to engage and activate an auxiliary switch. When the circuit breaker handle is moved to the ''''Off'''' position from the ''''tripped'''' or central position, the linkage mechanism simultaneously releases the actuator and the auxiliary switch is deactivated.
