Abstract
The utility model discloses a delay-action switch. A delay self-closing controlling circuit is composed of a PTC element, diodes Z1 and Z2, a relay J and a capacitor C. The delay-action switch is used for controlling the illumination lamp in the corridor, the entrance and other places. The delay-action switch has the advantages of simple structure, high stability and high reliability, the delay-action switch can automatically be closed after 40 to 60 seconds when the delay-action switch is opened, so the delay-action switch can realize the self-closing after people leave to achieve an electricity-saving purpose.
Description
The utility model relates to the switch that is used for the illuminating lamp automatic delay function.
Prior art has multiple structure delay-self-closing switch, be used for place uses such as corridor, generally speaking all be by rectification circuit, circuits for triggering, switching circuit constitutes, as CN8920537, the delay switch circuit of patent disclosures such as CN91207377 has all belonged to this structure C N89201755 patent disclosure a kind of delay switch circuit that uses semistor, its structure is to provide direct voltage by current rectifying and wave filtering circuit for load, on DC circuit, be serially connected with the switching circuit that constitutes by controllable silicon, the cross-over connection DC power supply is provided with circuits for triggering for it, provide delay control signal by the semistor PTC that is connected on the DC circuit for circuits for triggering, this delay switch circuit is for realizing turning circuit successively, be that two PTC with an end parallel connection cooperate with a duplex switch, instructions for use is satisfied in conducting again after finishing delay switch circuit and closing.Though this delay switch circuit has the characteristics of oneself, can still belong to circuits for triggering and switching circuit formation, the prior art concrete structure is not quite similar, and result of use is also different, is not all to be the ideal product that people use.
The purpose of this utility model provides a kind of delay switch.
The technical solution of the utility model is that the PTC element is serially connected with load circuit, utilizes its characteristic to be equipped with the control relay circuit switch on and off, finishes automatic delay function.
Accompanying drawing is the utility model circuit diagram.
The utility model includes housing, push-button switch, control circuit formation, it is characterized in that control circuit is by the full-wave rectifying circuit Z that is connected in the load circuit
1, Z
2Semistor t ° and the relay J that is connected in full-wave rectifying circuit one branch road constitute, the touch switch J-1 of relay is parallel on the power knob switch N, full-wave rectifying circuit provides direct-current working volts for relay J, and full-wave electric current is flow through in proof load, two ends in relay J are parallel with capacitor C, the operating voltage of stable relay J, after pressing power knob switch N, because t ° of resistance is very little, its touch switch of relay J adhesive J-1, current flowing, load lamp D lights.Because the characteristic of PTC element, its resistance raises rapidly and reaches cut-off state behind certain hour, makes the relay J voltage of losing the job, and relay J discharges its touch switch J-1, and thoroughly deenergization is finished automatic time delay and turned off the light.
The utility model is simple in structure, and good stability uses reliably, is specially adapted to the private residence entrance hall, and local illuminating lamp such as floor corridor uses, and opens the back and closes automatically in 45～60 seconds, reaches turn off the light when you leave the room, the purpose of economize on electricity.
Claims (1)
- A kind of delay switch especially for the illuminating lamp delay-self-closing switch that use in corridor, entrance hall, includes housing and mechanical touching button switch, control circuit formation, it is characterized in that the delay-self-closing control circuit is by the full-wave rectifying circuit Z that is connected in the load circuit 1, Z 2Positive temperature registration thermistor t 0Constitute with the relay J that is connected in full-wave rectifying circuit one branch road, be parallel with the capacitor C of stable relay J operating voltage at the two ends of relay J, relay touch switch J-1 is parallel on the power knob switch N.
