Abstract
A visual multi-point switch control circuit relates to an electric appliance switch circuit, which can overcome the defects of the prior art: the switch state and the electric appliance state are inconsistent, and the service voltage of a switch is same to the voltage of an electrical appliance. The visual multi-point switch control circuit is composed of a single switch and a two-way switch, and is characterized by comprising a step-down ballast circuit, a relay and an LED lamp; wherein while in use, the lighting state of the switch LED lamp is observed, and the working state of the electric appliance is known. The visual multi-point switch control circuit is safe and convenient. The circuit is mainly used on the power utilization circuit in need of multi-point switch control.
Description
Technical field:
The utility model relates to a kind of appliance switch control circuit.
Background technology:
Prior art: in the multiple spot control circuit that existing single connection plane switch and multigang switch form, although can accomplish to control same electrical appliance at a plurality of diverse locations, its shortcoming is that electrical appliance must can be seen in the position of each switch, otherwise, the residing state of switch is just not necessarily in good time corresponding with the residing state of electrical appliance, and namely the electrical appliance state corresponding to concrete certain state of certain switch is not unique.On the other hand the use voltage of switch also usually with the same voltage of electrical appliance, thereby safe not, and energy-conservation.
The utility model content
The technical problems to be solved in the utility model: a kind of visual multi-point switch control circuit is provided, can overcomes in the existing technology on off state and electrical appliance state inconsistent, and the use voltage of switch and electrical appliance are with the shortcoming of voltage.
The utility model is achieved in that a kind of visual multi-point switch control circuit, comprise single connection plane switch, ganged switch, it is characterized in that: also include two pressure reduction ballast circuit, relay and LED lamp, the pressure reduction ballast circuit is by transformer, the bridge-type ballast is in series, bridge-type ballast and the single connection plane switch of one of them pressure reduction ballast circuit, N ganged switch series connection, the single connection plane switch of connecting thereafter again, form N and add two switch control points, a rear single connection plane switch is connected with the relay coil joint again, relay other end coil connectors is connected with the bridge-type ballast, form a low tension loop, and the transformer input of this pressure reduction ballast circuit is connected with the normal pressure power supply; After the bridge-type ballast of previous pressure reduction ballast circuit and the series connection of the corresponding LED lamp of each switch, be connected with divider resistance, return and connect bridge-type ballast, the movable contact end that the transformer input of this voltage circuit and electrical appliance are parallel to relay.
After the current voltage one tunnel often of working directly enters the transformer pressure-reducing of pressure reduction ballast circuit of one of them, flow into the bridge-type ballast and become direct current, get back to the bridge-type ballast through single connection plane switch, ganged switch, relay coil successively again, another road of normal pressure electric current enters the movable contact of relay, electric current is flowed through and is divided again two-way behind the relay when the relay adhesive, one supply electrical appliance, electrical appliance work; Its two transformer that enters another pressure reduction ballast circuit flows through bridge-type ballast, LED lamp, divider resistance successively, returns the bridge-type ballast, and this moment, the LED lamp was lighted.
The beneficial effects of the utility model are: provide under a kind of safe voltage to operate, and can by observing switch LED illuminating state, know the Circuits System of electrical appliance operating state.Have safety, function easily.
