Background

An emergency flashlight is mainly used for escape lighting under emergency conditions such as power failure, earthquake, fire and the like. In order to prevent loss and facilitate taking, the emergency flashlight is usually fixedly stored at the eye display position, so that the emergency flashlight can be smoothly used under emergency situations, and the emergency flashlight needs to meet the function of being taken up and turned on and off. At present, the control switch of the emergency electric torch on the market mainly adopts the following three modes:

one is to separate the positive and negative electrodes of the battery by slotting to block the normally-on circuit to be extinguished. Common schemes are as follows: plastic slotting is placed at the installation position, the flashlight circuit is normally bright, the flashlight is forcibly clamped into the positive electrode and the negative electrode of the slotting physical separation battery to realize power-off and extinguishment when the flashlight is reset, the battery is restored to be connected under the action of the spring when the flashlight is taken out, and the flashlight is normally bright. The disadvantages of this approach are: when a user clamps the flashlight into the slotting, the flashlight is easy to physically break, and the slotting angle deviation is easy to cause battery damage and leakage.

One is to block the normally on circuit to off by a DC outlet. The common schemes are as follows: a DC plug is placed at the installation position, a DC base is arranged in the flashlight, the circuit is kept to be normally on, the plug is inserted into the DC base to physically separate a normally closed contact in the base to realize power-off and extinguishment when the flashlight is reset, the contact is recovered to be normally closed under the elastic action of a reed when the flashlight is taken out, and the flashlight is normally on. The disadvantages of this approach are: users are prone to physically deform or break when they snap the flashlight into the DC plug, resulting in a short circuit of the battery. Meanwhile, under the working condition of a waiting machine with high humidity and high salinity, the contact of the plug and the socket is exposed and is easy to oxidize and rust.

One is to block the normally on circuit to go off by a touch toggle switch. Common schemes are as follows: the installation position sets up the bump, and the built-in micro-gap switch of flashlight keeps the circuit bright normally, realizes that the outage goes out through the normally closed contact in the bump oppression physics separation micro-gap switch when the flashlight is playback, and the contact resumes normally closed under reed elastic action when the flashlight is taken out, and the flashlight is bright normally. The disadvantages of this approach are: the toggle switch is easy to physically deform under physical compression when the toggle reed is used for a long time. Meanwhile, under the working condition of a high-humidity high-salinity waiting machine, the contact of the wave switch is exposed and is easy to oxidize and rust.

The three emergency flashlights adopt the mechanical contact type physical power-off switch, so that the problems of deformation and breakage of mechanical parts of the switch, poor oxidation contact of a switch contact and the like are difficult to avoid, and the three emergency flashlights generally have the defects of easy damage, high failure rate and short service life in product use.
