Wiring using broken wire fluorescent lamp b

If the fluorescent lamp filament is broken, as long as the lamp tube does not leak or age, it can be used by changing the wiring
without affecting the normal light emission. If the filament at one end is broken, short-circuit the two pins at one end without changing the wiring, as shown in Figure 2-7 (a)
; if the filament at both ends is broken, short-circuit the two lamp pins at both ends, but the wiring needs to be changed . As shown in Figure 2-7 (b). When
in use, close the switch SAi, first put the switch SAz to the "1" position, and then move it to the "2" position, and the fluorescent lamp will start
and ignite.
