Description

Multipoint switch

The utility model relates to a kind of multipoint switch.

The normal multipoint switch that uses of current people, when Push switch, relay is explosive to go out spark, brings hidden danger to safety utilization of electric power.In addition, this multipoint switch will be in " standby " state, so not only power consumption, and the useful life of having reduced components and parts.

The purpose of this utility model is to provide a kind of multipoint switch, to overcome above-mentioned deficiency.

The technical solution of the utility model is:

This multipoint switch comprises by capacitor C ₁, voltage stabilizing didoe DW, diode D stabilized voltage power supply part, working portion, the switch sections formed, its working portion is by relay J ₂And capacitor C ₃Form relay J ₂And capacitor C ₃Stabilized voltage power supply part, the relay J of inserting in parallel ₂Switch be serially connected on the circuit of 220V with normally open;

Switch sections is by relay J ₁, capacitor C ₂, K switch forms relay J ₁And capacitor C ₂Parallel connection inserts the stabilized voltage power supply part, and connects relay J with working portion ₁Switch be serially connected on the circuit of 220V with normally off;

Relay J ₁Switch connect with K switch, with relay J ₂Switch in parallel be connected on the circuit of 220V.

K switch place a plurality of switches in parallel.

The utility model can be controlled the electrical appliance switch by multiple spot, brings great convenience to the user, because relay J ₂Switch be provided with ingeniously, make it have the advantage of " not turning on light not power consumption ".The utility model circuit design is reasonable, and not only eliminate the defective of relay dryness-fire flower, and had the outage memory function, but self-locking after the power failure, advantage such as cheap for manufacturing cost.

Fig. 1 is the utility model embodiment 1 circuit diagram;

Fig. 2 is the utility model embodiment 2 circuit diagrams;

Now be further described below in conjunction with the embodiments:

Embodiment 1: as shown in Figure 1, and moment Closing Switch K, relay J at this moment ₁Switch be normally closed.The power supply of 220V is through capacitor C ₁, obtain stabilized voltage power supply behind the voltage stabilizing didoe DW, diode D voltage stabilizing rectification, stabilized voltage power supply makes capacitor C ₃Charging is to relay J ₂Power supply, relay J ₂Work makes its switch closure, circuit turn-on, and electrical appliance L starts working.Stabilized voltage power supply is simultaneously to capacitor C ₂Charging is because capacitor C ₂The Capacity Ratio capacitor C ₃Big a lot, so the charging time-delay makes relay J ₁Work, relay J ₁Switch disconnect.

Moment Closing Switch K again, capacitor C ₃Short circuit dischange, relay J ₂Quit work relay J ₂Switch disconnect, electrical appliance L outage quits work.

Embodiment 2: as shown in Figure 2, and the same among its stabilized voltage power supply part and working portion and the embodiment 1, moment Closing Switch K, capacitor C ₃Charging, controllable silicon BT work make circuit turn-on, and electrical appliance L starts working, Closing Switch K once more, capacitor C ₃Discharge does not resupply controllable silicon BT, and controllable silicon BT disconnects circuit, and electrical appliance L outage quits work.

Claims (2)

1, a kind of multipoint switch comprises by capacitor C ₁, voltage stabilizing didoe DW, diode D stabilized voltage power supply part, working portion, the switch sections formed, it is characterized in that:

Working portion is by relay J ₂And capacitor C ₃Form relay J ₂And capacitor C ₃Stabilized voltage power supply part, the relay J of inserting in parallel ₂Switch be serially connected on the circuit of 220V with normally open;

Switch sections is by relay J ₁, capacitor C ₂, K switch forms relay J ₁And capacitor C ₂Parallel connection inserts the stabilized voltage power supply part, and connects relay J with working portion ₁Switch be serially connected on the circuit of 220V with normally off;

Relay J ₁Switch connect with K switch, with relay J ₂Switch in parallel be connected on the circuit of 220V.

2, multipoint switch according to claim 1 is characterized in that: a plurality of switches in parallel at the K switch place.
