摘要: A switch is configured that: in the closed-circuit state, at least part of its movable contact arm enters into a oblong generally hexahedral space defined by its elongated stationary conductor in its closed circuit position. Both contacting and breaking of the moving contact and the fixed contact occur in the space. Overall electromagnetic forces generated by the current flowing through the stationary conductor, movable contact arm and the arc induced at the time of breaking effectively act to extend the arc toward a terminal section of the stationary conductor and to increase the arc resistance at the time just after the breaking of both the contacts.

摘要: A semiconductor device accurately monitoring temperature of a semiconductor chip even in a noisy environment, while not requiring a highly accurate detection circuit. A PTC element is bonded onto an IGBT chip. Then, a constant current flows from a constant current source through the PTC element, and an output voltage of the PTC element is detected by a voltage monitor. When output voltage increases, a voltage applied to a gate electrode by a detection circuit is decreased. Since the PTC element is directly arranged on the IGBT chip, the temperature of the IGBT chip can be monitored with high accuracy. Further, since the change in output voltage of the PTC element per 1° C. is large, a highly accurate detection circuit is not necessary, thereby allowing accurate monitoring of the temperature of the IGBT chip even in a noisy environment.
