In some electronic device or some other device formed by the tubes, for several supply voltages, such as high pressure and low pressure should beturned on according to a certain order to start the low voltage. You may make a mistake if you are negligent. The use of LCE module can solve the problem. T1 is a low voltage transformer, its primary winding in series isin the LCE's ② feet; T2 is a high-voltage transformer, ofwhich the primary coil in series is in the LCE of ① feet. Normal start sequence should be: First pressing the switch S1, after a while, the vacuum tube filament ispreheating, and then pressing the switch S2. If the operation is in a reverse order, pressing the switch S2 make the circuit stop work, so you can ensure that procedures are correct.
