Exemplify most preferred embodiment below in conjunction with accompanying drawing:

Fig. 1 is the utility model structural representation;

Fig. 2 is a wall-mounted switch receiver schematic diagram of the present utility model;

Fig. 3 is a wall-hanging remote controller schematic diagram of the present utility model.

Among Fig. 1, remote control transmitter (1) is inserted in wall hanging socket (2) internal fixation hole (4) and is screwed on wall or head of a bed limit, indicator light (3) transmits on the panel, touch-switch (AN1 ', AN2 ', AN3 ') controls three the wall-mounted switch receiver of unequally loaded (A respectively, B, C,) low-light indicator light (5) is arranged on this receiver panel, manual switch button (6), press in the remote control transmitter panel any one key in three emission button touch-switchs (AN1 '～AN3 '), the pairing electronic switch gating of circuit board assemblies in the remote control transmitter, see that Fig. 3 is via C5 ' or C6 ', the LC frequency-selecting coding oscillating circuit that C7 ' and L2 ' BG2 ' form, the output of BG2 ' collector electrode, and to BG1 ', L1 ', the radio-frequency transmissions circuit that elements such as C1 ' are formed is modulated, and the signal after the modulation is launched by IX '.Be installed in three wall-mounted switch receivers in the indoor room, receive that simultaneously the frequency coded signal of reflector emission sees Fig. 2, signal after the reception is deciphered through LC frequency-selecting decoding circuit separately, if this LC frequency-selecting decoding frequency is consistent with the coding frequency that receives, then should produce the reception controller Be Controlled of resonance.In the receiving circuit control board assembly, TX, BG1 etc. form receiving loop, the code signal of this reception is formed the secondary amplifier through A1, A2 etc., signal after the amplification is deciphered by the LC frequency-selecting decoding circuit that L2, C13 form, if this road LC frequency-selecting decoding frequency is consistent with the coding frequency that receives, the LC frequency selection circuit resonance on this road then, output signal.Otherwise (, if the LC frequency-selecting on the coding frequency of receiving and this road decoding frequency is inconsistent, then this LC frequency selection circuit can not produce resonance, no signal output) signal behind the decoding gating amplifies through A3, and the Schmidt trigger circuit of forming through A4 is exported positive triggering level again, makes the upset of A5 trigger, put Q=1

=0, by A5's

The end output low level by collector electrode output high level, makes controllable silicon SCR 1 triggering and conducting through BG3 is anti-phase after, controllable silicon makes this road load connection as executive component, and the load control switch of the promptly wall-mounted switch receiver lamp that is unlocked is bright.If repeat above process again, make A5 trigger upset again, former output level is become low level by high level executive component SCR1 is closed, promptly lamp goes out.

Among Fig. 2, the electronic insurance loop is formed rectification circuit by D1～D4 and is made interchange become direct current, takes a sample through R27, the detection control circuit that BG4, BG5 etc. form, load current is detected, and when load current increased, the electric current among the R27 that flows through increased, then the pressure drop at R27 two ends also increases, if load overload or when being short-circuited, the electric current that then flows through R27 makes pressure drop surpass 0.7V, makes the BG5 conducting; BG4 is saturated; By BG4 collector electrode output high level, make A5 zero setting, i.e. the Q=0 of A5;

=1, by A5's

The output high level, through the anti-phase output low level of BG3, it is that load current is closed that SCR1 is closed.If it is normal that load current recovers, then the pressure drop of R27 is less than 0.7V, and then BG5 ends; BG4 ends, no zero setting level output, so reception control circuit recovers operate as normal, electronic insurance circuit has played safe and reliable overcurrent protection in receiving controller.

Working power in the present embodiment, because wall-mounted switch receiver does not have the input of 220V AC power is directly arranged, the working power that receives controller under the quiescent operation state is by circuit external load loop and diode D1～D4 rectification, resistance R 29 current limlitings, voltage-stabiliser tube D6 voltage stabilizing, capacitor C 19, C20 filtering, output 5V D.C. regulated power supply.When this circuit dynamic duty, the load switch that promptly receives controller is opened, controllable silicon SCR 1 conducting, this moment, SCR1 two terminal voltages were reduced to 1V, the primary coil that is connected on the current transformer B1 in the load switching circuit has load current to flow through, and secondary coil has induced voltage output, through rectifier diode D5, resistance R 30 current limlitings, voltage-stabiliser tube D6, C19, C20 filtering output 5V D.C. regulated power supply realize receiving controller needed working power when dynamic duty.X, Y represent two lines of the former switch of two terminations among Fig. 2.
