Document Type and Number:
Japanese Patent JP3604643
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a device capable of controlling ON/OFF of auxiliary electric equipment with the inexpensive constitution.
SOLUTION: Both ends of an operation switch 40 arranged in a driver's seat are wired and connected to a fixed side auxiliary contact piece 30G of a fixed side contact part 30 and a positive terminal of a battery B. Both fixed side main contact pieces 30E and 30F are respectively connected to positive and negative terminals of the battery B. Both movable side main contact pieces 35D and 35E of a movable side contact part 35 are connected to both input terminals of a battery charger 41. Positive and negative output terminals of the battery charger 41 are respectively connected to positive and negative terminals of a power source 42 for an apparatus, and are connected to a power terminal and a ground terminal of a latch circuit 43. The movable side main contact piece 35D and a movable side auxiliary contact piece 35G are respectively connected to an enable terminal E and a data terminal D of the latch circuit 43. A collector and a base of a transistor 45 are respectively connected to the positive terminal of the power source 42 for the apparatus and an output terminal of the latch circuit 43. Both ends of a laser pointer 47 are connected to an emitter of the transistor 45 and the negative terminal of the power source 42 for the apparatus.
