摘要： To electrically connect switch terminals of a housing and a control member in a switch for an electric tool with ease and to prevent the electric connection from becoming incomplete even when vibration occurs, elastic bodies for maintaining an electric connection are interposed between the control member and the switch terminals so that the control member and the switch terminals can maintain a stable connection even when vibration is imparted to the housing.

摘要： An improved phase controller is operatively connected to the operating lever or trigger of an electrically powered tool for supplying its motor with electric power from an ac power supply. It includes a device for establishing a divisional voltage derived from the ac voltage across the electric power supply. A variable resistor-and-capacitor series-connection is connected across the motor-and-power supply series-connection. A device provided for supplying the ac motor with electric power when the charging voltage across the capacitor rises above the divisional voltage. The variable resistor is operatively connected to the operating lever, and the capacitor can be charged with electricity at a charging rate which is determined by the variable resistance and the fixed capacitance under the control of the operating lever. The divisional voltage varies in the same way as the voltage across the ac power supply, thus permitting the ignition angle to remain substantially unchanged no matter whether the commercially available electric power may be of different cycles.
摘要翻译：改进的相位控制器可操作地连接到电动工具的操作杆或触发器，用于向交流电源的电动机提供电力。它包括用于建立从电源上的交流电压得到的分压的装置。可变电阻和电容器串联连接在电机和电源串联之间。当电容器两端的充电电压上升到分压以上时，提供给交流电动机供电的装置。可变电阻器可操作地连接到操作杆，并且可以在由操作杆的控制下由可变电阻和固定电容确定的充电速率下对电容器进行充电。分压电压以与交流电源两端的电压相同的方式变化，从而允许点火角度基本上保持不变，无论市售电力是否可以是不同的周期。
