Abstract: A circuit fixing member is provided which achieves a connection with a controlled object after a circuit module is produced, thereby avoiding disconnection of a wire member in the course of the production, easy to transfer between production processes, and is designed to avoid the entry of water into the circuit module. The terminal-embedded portion 110 of the circuit fixing member 10 which retains the control circuit 15 is equipped with a plurality of circuit supports 111 and the space 115 which communicates at an end thereof with the opened terminal insertion hole 117 and is closed at the other end thereof. For engaging the terminal fitting portion 130 of the terminal member 13 with the fitting portion 200 of the controlled object side terminal member 20 within the space 115, the terminal locking opening 114 and the terminal locking member 14 are provided. The terminal locking member 14 works to secure the locked portion 201 in the space 115.

Abstract: An ignition system includes a primary coil, a secondary coil, a first switch, a second switch, a third switch, a diode, and a switch control section. In the primary coil, a power supply is connected to a contact point between a first winding and a second winding. The secondary coil is magnetically coupled to the primary coil. The first switch is connected in series with the first winding. The second switch is connected in series with the second winding on the opposite side from the contact point. The third switch is connected in series with the second switch. The diode includes an anode connected between the second switch and the third switch and a cathode connected to the contact point. The switch control section controls opening and closing of each switch.
