Abstract

Normally, in the field of low voltage apparatus, there are different positions in a switch to drive auxiliary switches to output different signals, such as EARLY BREAK, STANDARD NO/NC (Normally Open/Normally Closed) and TEST. This means if the user needs many more signals for each kind of function EARLY BREAK, STANDARD NO/NC and TEST, a lot of positions must be designed in the switch to match many pieces of auxiliary switches to fit the requirement. It will need more space in the switch and it makes it impossible to realize the function in compact switches. Besides the complicated design with many installation positions, the interface is not friendly for users to use it. In the existing solution, there is a couple of shafts and sliders, which are close to each other to drive auxiliary switches to output different signals. At a position where the auxiliary switch is located, the shaft or the slider will drive auxiliary switches separately, and different output signals that depends on which part it will drive the auxiliary switches.

Normally, in the field of low voltage apparatus, there are different positions in a switch to drive auxiliary switches to output different signals, such as EARLY BREAK, STANDARD NO/NC (Normally Open/Normally Closed) and TEST. This means if the user needs many more signals for each kind of function EARLY BREAK, STANDARD NO/NC and TEST, a lot of positions must be designed in the switch to match many pieces of auxiliary switches to fit the requirement. It will need more space in the switch and it makes it impossible to realize the function in compact switches. Besides the complicated design with many installation positions, the interface is not friendly for users to use it.

In the existing solution, there is a couple of shafts and sliders, which are close to each other to drive auxiliary switches to output different signals. At a position where the auxiliary switch is located, the shaft or the slider will drive auxiliary switches separately, and different output signals that depends on which part it will drive the auxiliary switches.

In the proposed solution, as shown in Figure 1, the driving shaft 1, the cam 2, and the push slider 3 are installed in a frame. The push slider 3 is nested with cam 2. In another frame, the auxiliary shaft 4, the auxiliary slider 6, and the auxiliary switches for EARLY BREAK, STANDARD NO/NC and TEST are installed. The auxiliary shaft 4 is nested with the push slider 3.

Normally, part 1, part 2, part 3, part 4, and part 5 work together to realize the function of STANDARD NO/NC. Part 4 that is nested with part 3 can be operated by part 2 to provide ON and OFF positions. They match with part 2 driven by part 1 that will drive part 5 to realize the function of STANDARD NO/NC. Part 1, part 6 and part 5 work together to realize the function of TEST. Part 6 match with part 1 that will drive part 5 to realize the function of TEST. Also the function EARLY BREAK can be fulfilled via adjusting the actuator shape of part 4.

In this novel solution, as shown in Figure 2, there is a cam and a slider, part 2 and part 3, that are nes...
