    • A liquid level sensor-switch capable of effectively reducing variations in levels detected depending on directions in which it is inclined. The sensor-switch has a case, a guide rod formed therein, a float mounted on the guide rod with a clearance and being movable in the vertical direction along the guide rod in the case, an electrode plate attached to the bottom of the float and a pair of terminals disposed on both sides of the guide rod on the inside bottom of the case, wherein the float moves downward as the level of liquid lowers and it detects a specified low level by contacting the electrode plate with the paired terminals to make conductive a circuit formed between the terminals. It is featured by the fact that a pair of protrusions for restricting a biased movement of the float with respect to the guide rod are provided on both sides of the guide rod on the inside bottom of the case in a direction with a specified angle to a direction of arrangement of the paired terminals.
    • 一种液面传感器开关,其能够有效地减少根据倾斜方向检测的水平的变化。 传感器开关具有壳体,形成在其中的导杆,浮子,其安装在引导杆上,具有间隙,并且可沿壳体中的导杆在垂直方向上移动,附接到浮子底部的电极板, 一对端子,其设置在壳体的内底部的导杆的两侧,其中,当液面降低时,浮子向下移动,并且通过使电极板与成对端子接触来检测到指定的低电平,以使导电 形成在端子之间的电路。 其特征在于,用于限制浮子相对于导杆的偏置运动的一对突起在与壳体的指定角度相关联的方向上设置在壳体内底部的导杆的两侧 配对终端的布置方向。
