Embodiment
As shown in Figure 1, the how open/close control circuit of a kind of safety, by the transformation rectification circuit that is used for outside mains supply is converted to low-voltage safety power supply, be used for the directly outside open/close relay J 4 of electric light of control, be used for the relay unit of control relay J4 and point-touch switch K5 that one is used for the control relay unit and form; Behind the relay unit serial connection point-touch switch K5, be attempted by between the positive and negative terminal of transformation rectification circuit output; The transformation rectification circuit inserts outside civil power 220V AC power, and converts thereof into 12V direct current safe voltage power supply; The normally opened contact H41 of relay J 4 is connected in the electric power loop of external loading.
Wherein, relay unit has three relays, be respectively relay J 1, relay J 2 and relay J 3, an end is connected with the normally-closed contact D31 of relay J 3 and is inserted transformation rectification circuit output plus terminal after the normally opened contact H10 of relay J 1, relay J 2, the H20 parallel connection, and the other end connects the line bag control input end of relay J 1; An end is connected with the normally-closed contact D32 of relay J 3 and is inserted transformation rectification circuit output plus terminal after the normally opened contact H21 parallel connection of the normally-closed contact D11 of relay J 1 and relay J 2, and the other end connects the line bag control input end of relay J 2; An end is connected with the normally-closed contact D22 of relay J 2 and is inserted transformation rectification circuit output plus terminal after the normally opened contact H12 of relay J 1 and J3, the H30 parallel connection, and the other end connects the line bag control input end of relay J 3; The normally opened contact H13 of relay J 1 is connected in the control loop of relay J 4; After being connected in turn, the line bag control output end of the line bag control output end of relay J 3, the line bag control output end of relay J 2, point-touch switch K5, relay J 1 inserts the output negative terminal of transformation rectification circuit.
In relay unit, also has capacitor C in order to the 100 μ f that prolong 1 operating time of relay J, capacitor C is connected in parallel between the line bag control input end and output of relay J 1, this capacitor C is the operating time that also can keep several seconds zero point after delayed relay J1 is opened circuit by J3, make as after the H30 normally opened contact closure of relay J 3 self-insurances, just opened by the reduction of H10 normally opened contact, this can guarantee that relay J 1 and J2 can both quit work fully, have only relay J 3 in work, lamp just can be guaranteed to extinguish like this.
The positive and negative terminal of the control line bag two ends of the normally opened contact H13 of relay J 1, relay J 4, the output of transformation rectification circuit is linked to be the control loop of relay J 4; The control loop that also the normally opened contact H13 of relay J 1, the control line bag two ends of relay J 4, outside mains supply two ends can be linked to be relay J 4.
