Since the lengths of the first and second contact pieces are set so as not to occur, power is always supplied to the load in the rocket before, during, and after the switching of the movable contact. That is, when the movable contact is at the first position, the movable contact is connected to the first fixed contact, so that power is supplied from the power supply unit outside the rocket to the load inside the rocket. While the movable contact is rotating and switching to the second position, the movable contact is connected to both the first fixed contact and the second fixed contact. Power is supplied to the load from a power supply unit in the rocket. When the movable contact switches to the second position, the movable contact is connected to the second fixed contact, so that power is supplied from the power supply unit in the rocket to the load.

態となり、無接触時間は生じないこととなる。By the way, when the movable contact 16 switches from the state shown in FIG. 1 to the state shown in FIG.
Before moving away from 7a, the movable contact portion 16b comes into contact with the fixed contact portion 18a. That is, the movable contact portions 16a, 16b simultaneously contact the fixed contact portions 17a, 18a. Therefore, the movable contact 16 is in a state of being simultaneously connected to the fixed contacts 17 and 18 at the time of the switching, and the non-contact time does not occur.
換言すれば、第３図に示すように、時点t0でコイル13

時間は生じないこととなる。In other words, as shown in FIG. 3, the coil 13 at time t 0
current flows to a, the movable contact portion 16b at time t 1 is fixed contact portion 18
contacting the a, the movable contact portion 16a at the time point t 2 is spaced from the fixed contact portion 17a so that the switching from the external power source 2 to complete the internal power supply 4. That is, the movable contact portion 16a is between the time t 1 -t 2, 16b are simultaneously fixed contact portion 17a, in contact with the 18a, the load Z
Is supplied with power from one of the power sources 2 and 4, and no contactless time occurs.
