The loom saves electricity controller circuit is composed of knife switch Q, fuse FU, transistors VT1-VT3, resistors R1-R6, capacitors C1-C3, spring tubes SA1-SA2 and motor M, it is shown in the figure 8-20. Knife switch Q is turned on, the loom's machine open and shut down handle is pushed blak of the start-up position, under the magneticaction of machine open and shut down handle's permanent magnet, the spring tubes SA1-SA2's control contact is connected, VT1-VT3 are triggered and turned on, motor M runs. The sensitivity of V1-V3 trigger can be changed by adjusting R2, R4 and R6.
