Title:
不注意によるモータの起動を防止するべくスイッチの位置を検知する方法およびシステム
Document Type and Number:
Japanese Patent JP4685758
Kind Code:
B2
Abstract:
A method for preventing sudden inadvertent operation of a motor of a tool or appliance when the motor is initially electrically connected to a power source while an On/Off switch for controlling the motor is in a closed (i.e. 'On') position. The method includes electrically connecting the motor to a power source and determining a position of the On/Off switch when the motor is initially electrically connected to the power source. The position of the On/Off switch is determined by either sensing whether current is flowing through the motor or voltage is present at the motor when the motor is initially connected to the power source.
