Claims (1)
ークオフの切換えを行なうようにした装置において、前
記電磁弁のソレノイドコイルの制御回路にクラッチスイ
ッチを接続するとともに、このクラッチスイッチと並列
に自己保持用のスイッチを接続し、しかもこの自己保持
用のスイッチをパワー釡−クオフが接続状態に切換えら
れた場合にのみ閉成される位置に取付けるようにしたこ
とを特徴とするパワーテークオフの切換え装置。In a device in which power take-off is switched via an actuator by opening and closing a solenoid valve, a clutch switch is connected to a control circuit of a solenoid coil of the solenoid valve, and a self-holding switch is connected in parallel with the clutch switch. A power take-off switching device characterized in that the self-holding switch is mounted in a position where it is closed only when the power take-off is switched to the connected state.
