Embodiment

For further setting forth the utility model, do more detailed explanation below in conjunction with embodiment.

Used two single-pole double-throw switch (SPDT)s and two double-point double-throw switchs to be combined into a cover four point control switch combinations in the present embodiment.

Single-pole double-throw switch (SPDT) has three contacts, be connected with two moving contacts with a fixed contact of inside respectively, one movable feeler lever is arranged on the fixed contact, along with the action of the button of switch external contacts with a moving contact for the moment, in other words, the fixed contact of single-pole double-throw switch (SPDT) forever and in two moving contacts communicates.

The two pass commutator has six contacts, be connected with four moving contacts with two fixed contacts of inside respectively, movable feeler lever on each fixed contact, along with the action of the button of switch external contacts with a moving contact for the moment, two movable feeler lever synchronization actions, and four moving contacts are divided into two groups, in other words, two fixed contacts of double-point double-throw switch forever and two moving contacts in one group of moving contact communicate respectively.As seen Fig. 3, wherein contact 1,2 is two fixed contacts, contact 3,4,5,6 is four moving contacts, is divided into two groups, 3,4 one groups of contacts, 5,6 one groups of contacts, movable feeler lever 7,8 synchronization actions, such as showing among the figure, fixed contact 1 contacts with moving contact 5, and fixed contact 2 contacts with moving contact 6; When moving switch, fixed contact 1 will contact with moving contact 3, and fixed contact 2 will contact with moving contact 4.

In the present embodiment, double-point double-throw switch having been done some change, is exactly that four moving contacts 3,4,5,6 connect in internal chiasma, is exactly that moving contact 3 is connected with moving contact 6, and moving contact 4 is connected with moving contact 5.

Fig. 1 is the connection diagram of present embodiment, two two ends that single-pole double-throw switch (SPDT) is making up, wherein the fixed contact of first single-pole double-throw switch (SPDT) 20 connects power supply input V2, two moving contacts connect two fixed contacts of first double-point double-throw switch 40 respectively, four moving contacts of first double-point double-throw switch 40 connect two fixed contacts of second double-point double-throw switch 30 respectively after interconnection, four moving contacts of second double-point double-throw switch 30 connect two moving contacts of second single-pole double-throw switch (SPDT) 10 respectively after interconnection, the fixed contact of second single-pole double-throw switch (SPDT) 10 connects power supply output V1.

State shown in the image pattern 1, power supply input V2 is connected to the moving contact of the top of second single-pole double-throw switch (SPDT) 10 through the fixed contact of first single-pole double-throw switch (SPDT) 20, the moving contact of top, the fixed contact of top, first double-point double-throw switch, 40 left side, the moving contact of top, the fixed contact of second double-point double-throw switch, 30 tops, the moving contact of top, the left side, connect with following moving contact this moment owing to connect the fixed contact of the switch 1 of power supply output V1, whole combinational circuit is obstructed.

Move second single-pole double-throw switch (SPDT) 10, allow the fixed contact of second single-pole double-throw switch (SPDT) 10 and the moving contact of top connect, circuit is logical, and power supply is delivered to the power supply output point;

Move second double-point double-throw switch 30, the fixed contact of second double-point double-throw switch 30 and the moving contact on the right are connected, electric current just can pass through the moving contact of the moving contact of top, second double-point double-throw switch, 30 the right to second single-pole double-throw switch (SPDT), 10 bottoms, just in time on the moving contact of bottom, circuit is logical for the movable feeler lever of second single-pole double-throw switch (SPDT) 1 at this moment;

Move first double-point double-throw switch 40, the fixed contact of first double-point double-throw switch 40 and the moving contact on the right are connected, electric current passes through the moving contact on first double-point double-throw switch, 40 the right to the fixed contact of second double-point double-throw switch, 30 bottoms, again to the moving contact of second single-pole double-throw switch (SPDT), 1 bottom, and circuit is logical.

Move first single-pole double-throw switch (SPDT) 20, the fixed contact of first single-pole double-throw switch (SPDT) 20 and following moving contact are connected, electric current is by one group of contact of first double-point double-throw switch, 40 bottoms, one group of contact of second double-point double-throw switch, 30 bottoms, to the moving contact of second single-pole double-throw switch (SPDT), 1 bottom, circuit is logical at last.

As seen any one in four switches can be controlled the break-make of whole combination.

In this programme, middle two pass commutator is two, forms four point control; Its practical dpdt double-pole double-throw (DPDT) can be formed three point control, and three dpdt double-pole double-throw (DPDT) just can be formed five point control, when needing the some increase of control, can arbitrarily increase the quantity of middle double double-pole double throw switch.

The utility model also has another scheme, see Fig. 2, different with such scheme is the connection difference of second double-point double-throw switch 30, the line branch of being come by the moving contact of first double-point double-throw switch 40 is clipped on the moving contact of second double-point double-throw switch 30, the fixed contact of second double-point double-throw switch 30 is connected respectively with the moving contact of second single-pole double-throw switch (SPDT) 10, the difference of the connection of second double-point double-throw switch 30 does not influence the use of the utility model multipoint control switch combination, that is to say, in the utility model, two kinds of methods can be arranged for the connection of double-point double-throw switch.

As seen the utility model has used several switches just to realize the multiple spot of same electric equipment is controlled simply, very simple, owing to the existing switch that is mostly that uses, the reliability of this combination is also very high, price is also very cheap, autgmentability is fine, almost can expand arbitrarily, needing to be highly suitable for multiple spot control with the place with electric equipment.
