Description

Multichannel separate type two-way switch

The utility model draws and a kind of domestic switch, the especially a kind of multichannel separate type two-way switch that can remote control can manually control steel again.

Known civilian remote control switch has two kinds at present: a kind of is the remote control switch of a receiver of a reflector control, and this remote control switch is fairly simple, but can only satisfy an electrical appliance is carried out far distance controlled.Another kind is the remote control switch that a reflector is controlled a group of receivers, and the receiver of this remote control switch is concentrated and is assembled in the unit switch case, and each controlled electrical appliance is all from this unit switch case lead.This remote control switch, lead-in wire is complicated, and it is far away to be separated by between the electrical appliance, and can only remote control, can not carry out remote control and manual control simultaneously, can not carry out switch control to electrical appliance in case people can not find reflector.

The purpose of this utility model be to provide a kind of novel multichannel separate type manually, the remote control two-way switch.It separately can be installed by close respectively each controlled electrical appliance nearby with a plurality of independently receivers of portable transmitter control, each receiver.Each receiver profile is the same with the common wall switch: not only pattern, size the same (panel size meets the regulation of GB1245-87 " electric accessory concealed installation with panel, adjust plate and line box " standard), and also mounting means (can be directly installed in the terminal box of GB1245-87 regulation) too.The utility model not only can carry out the remote control of switch to each electrical appliance with reflector, and can carry out the manual control of switch as the common wall switch respectively to each electrical appliance with the hand push button on the receiver panel.Manually, two kinds of functions of remote control mutually independent, do not disturb mutually, control freely.The terminal part of the utility model receiver is a bidirectional triode thyristor, and therefore, it not only can be used for family and also can be used for the explosion-proof occasion of other any needs.It can drive various resistive, capacitives and inductive load, and by selecting the bidirectional triode thyristor of different capacity for use, but this switch driving power reaches thousands of watts electrical appliance.The utility model power consumption is very little, can be long towards being installed in the wall as the common wall switch.

The purpose of this utility model is achieved in that

The utility model comprises a reflector and N receiver (N1=1～16 are as follows usually).Reflector is a portable capsule, a little battery main switch, a N firing button switch, battery is housed in the box and the printed circuit board of electronic devices and components is housed.Radiating circuit is made up of frequency selection circuit, oscillating circuit, modulation transmitter and power supply.

The receiver profile is a N switch enclosure.Each switch enclosure is made up of panel and the inner box that all connects together with panel behind panel.Panel size meets the requirement of GB1245-87.A hand push button and an indicator light are arranged on the panel.The panel inner box can be packed in the GB1245-87 specified standard terminal box fully.Therefore each receiver profile with now use switch on wall about the same, only be that inner box is slightly bigger, install very conveniently, meet very much people's use habit.Printed circuit board and binding post that electronic devices and components are housed are arranged in the inner box.Receiving circuit is by the receiving demodulation device, and decoding circuit automatically, is manually selected and level shifting circuit, monostable, bistable and automatic zero-set circuit, and power driving circuit and power circuit are formed.
