An elastomeric switch cover configured for use on automotive switch panels and a method of use is described in this application. The elastomeric switch cover prevents the intrusion of water or moisture from damaging door mounted switches in vehicles. The switch cover can easily be fitted and removed or peeled back to provide access to the protected switch panel.

A resin structure includes a molded resin element and a push-type switch. The push-type switch includes a receptacle whereon a first terminal and a second terminal are secured, the first terminal and the second terminal configured to connect to an electrical circuit; a button unit protruding from the receptacle; and a contact spring unit configured to move with the button unit, to electrically connect between the first terminal and the second terminal, and to generate an opposing force relative to a pressure applied between the receptacle and the button unit. The receptacle stores the button unit and the contact spring unit. The receptacle of the push-type switch is embedded in the molded resin element with the button unit exposed from the molded resin element.

An energy storage operation mechanism for a circuit breaker comprises a side plate assembly, a connecting rod assembly, a cam assembly, an energy storage assembly, a rotating shaft assembly and a control assembly. A rotatable driving shaft is mounted in the side plate assembly. The connecting rod assembly and the cam assembly are mounted on the driving shaft. The energy storage assembly and the rotating shaft assembly are mounted at one side of the driving shaft, and the control assembly is mounted at the other side of the driving shaft. The connecting rod assembly is connected with the rotating shaft assembly. The cam assembly can be in contact and connection with the energy storage assembly to push the energy storage assembly to store energy. The control assembly can be connected with the connecting rod assembly and the cam assembly in a latching manner. The energy storage operation mechanism for the circuit breaker, which is provided by the present invention, is compact in structure and high in reliability.

Disclosed herein is a pole component assembly for a circuit breaker. The pole component assembly for a circuit breaker includes an external insulating housing made by injecting resin into a housing mold, applying injection pressure to mold the injected resin, and separating the molded resin from the housing mold, and a circuit breaker portion assembly detachably inserted into the external insulating housing after the external insulating housing is made. According to embodiments of the present disclosure, the external insulating housing is molded without a main circuit breaker component when manufacturing a sealed type pole component, and the main circuit breaker component is assembled into the finished external insulating housing, thereby preventing the main circuit breaker component from being contaminated or damaged.

An interlocking device for a circuit breaker comprises a control assembly and an interlocking assembly which are connected with each other in a driving manner. The control assembly can be connected with a connecting rod assembly and a cam assembly of an energy storage operation mechanism of the circuit breaker in a latching manner, thereby controlling the energy storage operation mechanism to finish a switching-on/switching-off operation. A switching-off latch of the control assembly is connected with the connecting rod assembly, and a switching-on latch of the control assembly is connected with the cam assembly. A switching-on guide rod of the interlocking assembly is connected with the control assembly in a driving manner, such that the switching-on latch actuates, and a switching-off guide rod of the interlocking assembly is connected with the control assembly in a driving manner, such that the switching-off latch actuates. One end of a switching-on half-shaft is connected with the switching-on latch in a driving manner, and the other end of the switching-on half-shaft and the driving guide rod face each other. The interlocking device for the circuit breaker, which is provided by the present invention, is compact in structure, accurate in control and stable in action.
