Description
Technical field
The present invention relates to a kind of electronic time-delay switch, specifically refer to a kind of electronic time-delay switch of meeting an urgent need and opening by force.
Background technology
In order to take into account hommization and energy-conservation, between the building ladder or the illumination of passage extensively adopt: infrared induction, acousto-optic control, touch electronic time-delay switch such as time-delay.The common feature of this type switch is: open when satisfying trigger condition, close automatically after continuity a period of time.For security against fire, this electron-like delay switch is asked to be designed to: except fire line terminal (L end) and face terminals (A end), must have enforced opening control terminal (C end).During installation, the enforced opening control terminal of all switches (C end) is connected in parallel on the emergency power supply line, and the emergency power supply line does not connect power supply at ordinary times, and electronic time-delay switch can normal switch.Need throw light on when ensureing when running into fire-fighting or other accidents, enforced opening control terminal (C end) and fire line terminal (L end) insert same emergency power supply, and all lighting loads that are in closed condition will be forced unlatching, throw light on assurance.The switching circuit of electronic time-delay switch controllable silicon commonly used is a switch element at present.The electronic time-delay switch of old scheme comprises: switching circuit, switch driving circuit, power supply circuits, delay control circuit, sensing circuit, (C end) signal deteching circuit; Switching circuit is series in the electricity consumption loop and is connected with drive circuit and delay control circuit output successively and controlled by it, and sensing circuit (can be various kinds of sensors or sensor combination such as infrared induction, acoustic control, light-operated, remote control, touch) is connected with the triggering signal input of delay control circuit and is used to trigger delay switch; (C end) signal deteching circuit is connected between face terminals (A end) and the enforced opening control terminal (C end); Its output is connected with switch driving circuit; Whether be used for detecting (C end) has electric current to flow through; If do not detect electric current, delay switch normally uses, in case detect electric current with regard to the enforced opening switching circuit.
