Two switches are installed at one end near the output terminal, the coil generates the next action, both ends are magnetically attracted to operate the switch in the on state, input from one input terminal and output by two output terminals. However, it is a circuit operation of 1 input and 2 output, and the distance between the switch set (that is, the two output terminals) of this relay operation mode has only the distance between the contacts of a single set, and the contact distance is relatively small. Moreover, the arc blocking ability is also limited. The application of a relay is determined by the conductive bullet pieces of the switch set, and the conductivity equation of the relay is related to the conductive area and ratio parameters, and conventionally increases the applicable high current amount of the relay, so that the conductive bullet pieces Normally, the overall thickness of the conductive bullet is increased without changing the material, but when the thickness of the conductive bullet is increased inside the relay, the acting force generated by the coil reliably attracts the conductive bullet. It cannot be moved, the number of turns of the coil needs to be increased, and the current electronic components always completely fill the internal space, making it even more difficult to move the conductive pieces into the relay. ing.
