A switch that can be switched between on and off by the operator's operation ,
It has a first signal line that is connected to the switch and outputs a first signal indicating that the switch is in the on state or the off state to the control unit .
The control unit is a power tool configured to switch between the driving state and the stopped state of the motor when the switch is switched from the off state to the on state.
The power tool is further connected to the switch and has a second signal line that outputs a second signal indicating that the switch is in the on state or the off state to the control unit.
When the operator operates the switch when the first signal line and the second signal line are not disconnected in the stopped state, the control unit switches the motor from the stopped state to the driving state and at the same time. When one of the first signal line and the second signal line is disconnected, the motor is controlled based on the signal input from the other signal line .
It may be configured so that the motor is not switched from the stopped state to the driven state even if the operator operates the switch when the stopped state and the first signal line are disconnected.
When the operator operates the switch when the drive state and the first signal line are disconnected, the motor may be configured to switch from the drive state to the stop state.
When the second signal line is disconnected in the driving state, the motor may be automatically switched from the driving state to the stopped state regardless of the operation of the switch.
The first signal includes a first on signal.
The second signal includes a second on signal.
In the on state, the switch transmits the first on signal to the control unit by the first signal line, and transmits the second on signal to the control unit by the second signal line.
When the control unit detects both the first on signal and the second on signal, the control unit may switch between the drive state and the stop state of the motor.
前記第１信号は第１オフ信号を含み、
前記第２信号は第２オフ信号を含み、
前記スイッチは、オフ状態において、前記第１信号線によって前記第１オフ信号を前記制御部に送信するとともに、前記第２信号線によって前記第２オフ信号を前記制御部に送信してもよい。
The first signal includes a first off signal.
The second signal includes a second off signal.
In the off state, the switch may transmit the first off signal to the control unit by the first signal line and may transmit the second off signal to the control unit by the second signal line.
前記制御部は、前記第１信号線が断線した場合に前記モータの始動を規制するとともに、前記第２信号線が断線した場合にも前記モータの始動を規制するよう構成されてもよい。 The control unit may be configured to regulate the start of the motor when the first signal line is disconnected, and to regulate the start of the motor even when the second signal line is disconnected .
作業者の操作によって前記スイッチの前記オン状態と前記オフ状態とを切り替える操作部を有し、
前記操作部は、オン位置に移動させる操作力が加えられている間はオン位置にあり、前記操作力が無いときはオフ位置にあり、
前記スイッチは、前記操作部が前記オン位置にあるときはオン状態、オフ位置にあるときはオフ状態となってもよい。
It has an operation unit that switches between the on state and the off state of the switch by the operation of the operator.
The operation unit is in the on position while the operation force for moving to the on position is applied, and is in the off position when there is no operation force.
The switch may be in the on state when the operation unit is in the on position and in the off state when the operation unit is in the off position.
