Switches are the most essential devices in an electric field. The main function of a switch is to open or close an electrical circuit. Generally, the electric circuits change from simple make or simply break circuits to multi make or multi-break circuits. Although the logic is very simple, s...
switches 元器件是什么 electrical switch 电路交换 英文名称: circuit switching 电话网中就是采用电路交换方式。人们可以打一次电话来体验这种交换方式。打电话时,首先是摘下话机拨号。拨号完毕,交换机就知道了要和谁通话,并为双方建立连接,等一方挂机后,交换机就把双方的线路断开,为双方各自开始一次新的通话做好准备...
Normally-open and Normally-closed For instance, the following diagram shows a normally-open pushbutton switch controlling a lamp on a 120 volt AC circuit (the “hot” and “neutral” poles of the AC power source labeled L1 and L2, respectively): We can tell this switch is a normally-open...

type of toggle switch with an electrical latching mechanism. The latching mechanism (internal solenoid in the switch) is designed to hold the momentary switch contacts closed once the toggle switch has been manually actuated. An auxiliary set or remote set of contacts opens the solenoid circuit of...
Refer to circuit diagram on switch’s cover. Insert the terminals into the switch and then fully fix terminal screws: 0,5 Nm to 0,6 Nm [4.42 in-lb to 5.31 in-lb].9. Perform functional tests. After wiring, use a voltmeter to ensure when the switch is operated (turned off and on)...
