This invention features that within the pull switch, there are 2 sub-switchs, K1 and K2 which are mounted in sequence to put on or off, while their connecting points are completely separated. If this invention is in use, circuit is cut off by hand pulling and sound hearing during outage, especially, the fluorescent lamp circuit can be cut-off automaticully. Moreover, no starter is required for put on the fluorescent lamp. after testing, with normal speed to pull twice the cord of the switch, it requires about 2 seconds from put on K2 till working of the fluorescent lamp, which is nearly the same as that done by the starter, but when said invented switch is used for starting the fluorescent lamp, it is reguired to put off K2 once, thus, only once high voltage pulse is applied on the lamp tube, so its lifetime is greatly increased. |
