The present invention provides a combined travel switch. The combined travel switch comprises: a housing, wherein the housing has a first touch space and a second touch space; a button partially arranged in the housing; a first contact bridge, wherein the first contact bridge is connected with the button and is arranged in the first touch space; a second contact bridge, wherein the second contactbridge is connected with the button and is arranged in the second touch space; a first contact member partially arranged in the first touch space; and a second contact member partially arranged in thesecond touch space. According to the combined travel switch provided by an embodiment of the present invention, by dividing two spaces in the switch, and by respectively placing the first contact bridge and the first contact member, the second contact bridge and the second contact member in the two spaces, switch setting inside the two spaces is realized, and the staff can only press the button to simultaneously realize the opening and closing control of the two circuits.

The invention discloses a bidirectionally identifiable microfluid inertial electric switch, which comprises a base, a cover plate, metal droplets, metal electrodes and microchannels. The cover plate is located at the upper end of the base, and the two are sealed; the microchannel is arranged on the base; the metal electrode is arranged on the cover plate; Valves, straight channels and bends; the metal droplet is located in a rectangular reservoir. One end contact of the metal electrode is located in the microchannel, and the other end contact is located outside the overlapping area of ​​the base and the cover plate. When the inertial force on the switch is greater than its threshold, the metal droplet will break through the capillary valve. After the recoil load and service load disappear, the metal droplet can completely return to the rectangular liquid storage pool. Under the action, the metal droplet conducts the switch and is irreversible. The invention can bidirectionally identify the acceleration load, stably connect electricity, and has the performance of working in a low temperature environment.

The invention discloses an intelligent circuit breaker with the phase selection function, which comprises a shell and a phase selection device in the shell, wherein the phase selection device comprises bistable permanent magnet mechanisms and a yoke plate mechanism, the bistable permanent magnet mechanisms are three groups of electromagnetic mechanisms, and each transmission rod is simultaneouslyengaged to or disengaged from the yoke plate mechanism to realize the simultaneous advancing and retreating opening / closing or single-phase advancing and retreating opening / closing of a three-phase circuit. By adopting the novel bistable permanent magnet mechanisms and the yoke plate mechanism, the intelligent circuit breaker not only has synchronous on and off capability but also has split-phaseselection on and off capability, and can be used as a reclosing device by equipping a reclosing controller; and the intelligent circuit breaker can also be used as an opening switch by equipping an intelligent controller. Meanwhile, the mechanisms are loaded into an SF6 air tank shell to avoid pollution and rusting by the external environment; and the switch shell is subjected to frosting and solid insulation heat isolating treatment so as to increase the insulating property and reduce the size of the switch, and the internal and external connection part of the switch is subjected to double-layer sealing treatment, thus the service life of the switch can be prolonged to more than 30,000 times, and the switch is applicable to frequent operation.

The invention discloses a pressing type travel switch resisting severe environment. The pressing type travel switch is composed of a shell, a drive body assembly, a base assembly and a pressing spring. The base assembly comprises a base body and at least one set of contact bars. The drive body assembly comprises a drive body, a button and at least one drum-like contact spring part. The number of the drum-like contact spring parts is the same as that of the sets of the contact bars. A locating boss on the base body and a locating blind hole in the drive body are located on the same axis. The upper end of the pressing spring is fixedly embedded into the locating blind hole. The lower end of the pressing spring is fixedly embedded outside the locating boss. The shell is a housing with a penetration hole formed in the center of the top. According to the travel switch, the drum-like bundling type contact springs with multiple elastic contacts are adopted, multi-point elastic surrounding uniform contact with the contact bars can be achieved, and the travel switch has the advantages of being high in impact resistance, high in vibration resistance, miniaturized, high in reliability, low in cost and the like.
