JPH10233272A - Middle switch with connector - Google Patents

Abstract

PROBLEM TO BE SOLVED: To fit a middle switch promptly, safely, and exactly even by an inexperienced man without using a tool in the case of necessity by forming a plug and a receptacle as a connector respectively on the input side and output side of the middle switch. SOLUTION: In the case of using an interrupted middle switch, the receptacle of an extension cord is inserted into the plug 4 of a middle switch box 3 which involves a slide switch 2, the plug of an appliance used is inserted into a receptacle 1. By forming such a structure as plugs of a plurality of appliances used are inserted into a plurality of receptacles formed on the output side so as to switch the slide switch, it is possible to be used as a middle change-over switch. In this case, by leaving one receptacle of the output side open, the switch is possible to use as an interrupted intermediate switch. By forming like this, thus it is possible to use the switch immediately without professional connection work.

Description

DETAILED DESCRIPTION OF THE INVENTION

When using an electric appliance, a switch is usually provided on the appliance, but depending on the use situation, it may be desirable to provide an intermediate switch. Even if a commercially available intermediate switch is purchased, it is difficult for an unskilled person to connect wires, so the intermediate switch box (3) itself has a connector, that is, a plug (4) on the input side and an outlet (1) on the output side. Keep it. In the case of an application for switching a plurality of appliances, the intermediate switch is provided with outlets (1) A, B, and C of the number of switching circuits.

[Industrial applications]

[0002] The present invention relates to control of electric appliances.

[Prior art]

In the use of a conventional intermediate switch, it has been common practice to strip the electric wire and then tighten it with terminal screws.
Wires used for general electric appliances are usually bundles of a plurality of fine wires, and specialized work such as tightening with screws without leaving any beard was required.

[Problems to be solved by the invention]

[0004] When an intermediate switch is required, it is an object of the present invention to enable a layman to quickly and safely perform a reliable operation without tools.

[Means for Solving the Problems]

[0005] In the case of intermittent control of an electric appliance on the way, a plug (4) and an outlet (1) are provided on the input side and the output side of the intermediate switch (2), respectively. Similarly, when selecting and using a plurality of appliances, plugs (4) are provided on the input side, and outlets (1) A, B,
Equip C.

[Action]

[0006] When using the intermediate switch, the outlet of the extension cord is inserted into the plug of the intermediate switch box (3) of the present invention, and the plug of the tool to be used is inserted into the outlet (1) of the intermediate switch box (3) of the present invention. Similarly, in the case of the intermediate changeover switch, only the plug of the extension cord is inserted into the plug (4) of the intermediate switch (3) of the present invention, and the plug of a plurality of appliances is inserted into the outlet (1) of the intermediate switch box (3) of the present invention. And can be used immediately without specialized wiring work.
Needless to say, if one place is left in the multiple changeover switch box (3), it functions as an intermittent intermediate switch.

【Example】

In the application of the intermittent intermediate switch, a switch box (3) equipped with a plug (4) and an outlet (1) at both ends of the switch (2) is prepared. In addition, a switch box (3) in which a plug (4) is connected to the common terminal of the switch (2) and an outlet (1) is connected to the switching contact terminal side is prepared for the use of the intermediate changeover switch. Although there are two types of switches, one-sided and two-sided, depending on the purpose of use, the latter is desirable from the viewpoint of safety, even if the connection is complicated. In the embodiment, a switch box (3) using a double-sided slide switch having a plurality of circuit contacts was prepared, and the outlet (1) was used at one place to use the function of the intermittent intermediate switch.

【The invention's effect】

If a switch box equipped with a plug and an outlet is prepared in advance as in the present invention, an electric appliance can be intermittently connected or disconnected even by an unskilled layman in the manner of inserting a plug into a wall outlet. It can be selected and easily removed when not needed.

Claims (2)

[Claims] 1. A structure of an intermittent intermediate switch in which connectors are provided for input and output of electric power, respectively. 2. The structure of a circuit switching intermediate switch in which a plurality of connectors are provided for one input in the intermediate switch.
