Claims

[Scope of utility model registration request]

In an electric switch machine equipped with a circuit controller that converts the tongue rail using a motor and connects and disconnects the motor and the motor power supply based on the switching operation, the motor and the motor power supply are cut off by the circuit controller. A brake device is provided to brake the operation of the point machine after the switching operation is completed, an existing voltage generator is connected to the brake device as a brake drive source, and a tongue rail is installed between the drive power source and the brake device. The contacts of the circuit controller are turned on only during the period from the start to the end of the switching operation from the normal position to the opposite position, and the contacts of the circuit controller are turned on only during the period from the start to the end of the switching operation from the opposite position to the normal position. A series circuit with the contacts of the circuit controller is connected, and between the series circuit of both contacts and the brake device, the positioning contacts of the circuit controller and the tongue rail, which are turned on when the tongue rail completes switching to the positioning side, are connected. Connect a parallel circuit with the opposite position contact of the circuit controller that turns on when the conversion to the opposite position is completed, and connect it in parallel with the parallel circuit of the positioning contact and the opposite position contact and the series circuit of the brake device. A brake drive circuit for an electric point machine characterized by being provided with a charging capacitor.
