Abstract

The utility model belongs to the class of electric appliance elements and overcomes the inconvenience caused by that a switch is usually fixedly installed in a definite position in the prior art to users. The convenient switch is composed of a wall switch and a hand switch which are connected by special leading wires and socket connectors; a socket for a general electric appliance, which is controlled by the switch, is arranged on a panel of the wall switch to enlarge the control range of the switch on other electric appliances. The hand switch can be moved to any places in a room, so great convenience is brought for users and especially old, weak, sick and disabled people.

Description

Convenient switch

The utility model belongs to the low voltage component class, and it relates to a kind of novel switched structure.

As everyone knows, that generally installs in the room mostly is switch wall type or stay-supported, and they all are single control and are fixed on a switch on the particular location, mostly are the single electrical equipment of control and use.Easy to use in order to enter, the switch of headlight is located at a limit more within doors, but also must go operation to a door limit when turning off the light, and this is very inconvenient for old, weak, sick, residual person's use sometimes.

The purpose of this utility model is for a kind of novel Convenient switch of the special proposition of the inconvenient part that overcomes fixing Wall-type switch, it provides another can be placed on the switch of any position hand-hold type, two switches are control circuit and electrical equipment respectively, for the user provides great convenience.

By as above design, the Convenient switch that this programme provided, it includes two single-pole double-throw switch (SPDT)s, it is characterized in that a single-pole double-throw switch (SPDT) in this Convenient switch is the form of Wall-type switch and another single-pole double-throw switch (SPDT) is the switch of hand-hold type, these two switches are controlled a single phase circuit for the form of series connection.

In this programme, its circuit is the series connection of two switches, and promptly two spiral arm ends are serially connected on the line of single phase circuit, and two selected ends in two switches connect respectively.The single-pole double-throw switch (SPDT) of its hand-hold type is to link with the plug of a special use and the private jack that draws on residual and the Wall-type switch.Also be provided with the connector socket of being controlled by this switch on the plate face of its Wall-type switch.The plug and socket of its special use has three connection elements, its distance do not wait, on plug, have a projection, plug and socket in conjunction with the time this projection the normally-closed contact between two nodes in the socket can be opened.

Adopt this programme can embody following superiority: 1. in the Convenient switch of this programme, though two switches be serially connected among the circuit, can be respectively control circuit or electrical equipment individually, especially provide great convenience to the user to old, weak, sick, residual people; 2. also be provided with the appliance socket of being controlled by switch on the panel of this switch, this switch is gone back other electrical equipment of may command except that the control electric light; 3. the switch of its hand-hold type connects with special-purpose lead-in wire and plug connector, and hand held switch is the shift position arbitrarily, makes operation very convenient, also can avoid other electrical equipment is inserted faulty operation in two switching circuits with the connector of special use; 4. its simple in structure, low cost of manufacture is convenient to make and promote the use of in batches.

Fig. 1 is the profile schematic diagram of Wall-type switch in this programme Convenient switch.

Fig. 2 is the profile schematic diagram of hand-hold type switch.

Fig. 3 is the electrical schematic diagram in the Wall-type switch.

Fig. 4 is the electrical schematic diagram in the hand held switch.

The embodiment of existing accompanying drawings this programme.This Convenient switch is made up of the switch of two single-pole double throws, on the panel of Wall-type switch 1, also be provided with special-purpose socket 2 and the common socket of being controlled by this switch 3, the lead-in wire that hand-held switch 4 usefulness are special-purpose and the private jack 2 of plug 5 and Wall-type switch 1 link, electric principle relation between them is that the spiral arm with two switches is serially connected in the line in the single phase circuit, and two selected ends of each switch connect respectively.Hand held switch can move to indoor any position, can bring great convenience to the user.Between two nodes that two distances are far away in the socket of special use a normally-closed contact 6 is arranged, its normally-closed contact combination when not inserting special-purpose plug, then the single-pole double-throw switch (SPDT) of wall type can be worked individually, after the plug of special use inserts, projection on the plug can be opened the normally-closed contact in the socket, and two switches can be controlled its circuit and were independent of each other this moment.

The preproduction of this programme proves through test run: it has spy easy to use, simple in structure Point is convenient to make and promote the use of in batches.

Claims

1. Convenient switch, it includes two single-pole double-throw switch (SPDT)s, it is characterized in that a single-pole double-throw switch (SPDT) in this Convenient switch is the form of Wall-type switch (1) and another single-pole double-throw switch (SPDT) is the switch (4) of hand-hold type, these two switches are controlled a single phase circuit for the form of series connection.

2. according to the described Convenient switch of claim 1, the circuit that it is characterized in that it is the series connection of two switches, and promptly two spiral arm ends are serially connected on the line of single phase circuit, and two selected ends in two switches connect respectively.

3. according to the described Convenient switch of claim 1, the single-pole double-throw switch (SPDT) that it is characterized in that its hand-hold type is to link with the private jack (2) on the lead-in wire of a special use and plug (5) and the Wall-type switch.

4. according to the described Convenient switch of claim 1, it is characterized in that on its plate face of Wall-type switch, also being provided with the common socket of being controlled by this switch (3).

5. according to claim 1 or 3 described Convenient switches, the plug and socket that it is characterized in that its special use has three connection elements, its the distance do not wait, on plug, have a projection, plug and socket in conjunction with the time this projection the normally-closed contact between two nodes (6) in the socket can be opened.
