Abstract

The utility model provides a strypped-down pulling thread switch for daily lighting. The utility model comprises a box cover, a box seat, a pulling thread, a middle shaft fixed in the box seat, a resetting spring sheathed on the middle shaft, a pulling thread piece, a rotor, a live wire inlet contact piece and a live wire outlet contact piece. The utility model is characterized in that the pulling thread switch also comprises another rotor which can be connected in detachable way with the rotor and can rotate synchronously with the rotor, a zero wire inlet contact piece contacting with the rotor, and a zero wire outlet contact piece. The pulling thread switch can simultaneously control the on-off of the live wires and the zero wires. The pulling thread switch has the advantages of greater safety and reliability. People can not mistakenly install the utility model, even if common men, so potential danger is avoided.

Description

A kind of pulling switch

The utility model belongs to the technical field of the electric switch of normal lighting circuit.

As everyone knows, the used pulling switch of our normal lighting circuit is only controlled the break-make of a line (being live wire) with a rotor contact device, and zero line is without pulling switch.But in daily life,, when oneself installs pulling switch, often zero line is inserted switch, so just can not disconnect live wire, often cause danger, lead to a disaster because many people have half knowledge to electrician's knowledge or are ignorant of at all

The purpose of this utility model provides a kind of pulling switch that is applicable to the normal lighting circuit that can control live wire and zero line break-make simultaneously.

The purpose of this utility model is achieved in that sets up the break-make that a cover rotor contact device is controlled another line (being zero line) in existing common pulling switch, between the rotor of setting up and the former rotor is removable the connection, but synchronous interaction, when the pulling backguy, two rotors can rotate synchronously, reach the purpose that is switched on or switched off live wire and zero line simultaneously

Because the utility model adopts the birotor contact device to control the break-make of two lines (being live wire and zero line) simultaneously, can avoid the danger that causes because of mis-wired like this.Because the utility model just increases a same rotor contact device, so structure is still very simple

Be illustrated below in conjunction with drawings and Examples:

Fig. 1 is a schematic appearance of the present utility model;

Fig. 2 is the utility model internal structure schematic diagram;

Fig. 3 is the utility model internal structure exploded view

As Fig. 1, Fig. 2, shown in Figure 3, this pulling switch is by lid 1, cassette holder 2, backguy 3, axis 4, return spring 5, backguy sheet 6, rotor 7, rotor 8, inlet wire contact chip 9 and 10, outlet contact chip 11 and 12 constitutes, rotor 7 is provided with rectangle projection 13, it is concavo-convex embedded linking to each other between them that rotor 8 is provided with corresponding rectangular recess 14, live wire and zero line all can insert switch from inlet wire contact chip 9 and 10 respectively, pick out from outlet contact chip 11 and 12 accordingly, when the pulling backguy, the backguy sheet drives the rotor 7 that is attached thereto and rotates, rotor 7 drives rotor 8 simultaneously and rotates, and can reach the break-make of controlling two lines (being live wire and zero line) simultaneously.The profile of switch box body (being lid and cassette holder) can be made into rectangle, and the connection between garden shape or other geometric form, two rotors also can be adopted other removable connection, can reach synchronous interaction and get final product.

Claims (2)

1, a kind of pulling switch that is applicable to the normal lighting circuit, comprise lid (1), cassette holder (2), backguy (3), be fixed on the axis (4) in the cassette holder, be enclosed within the return spring (5) on the axis, backguy sheet (6), rotor (7), live wire inlet wire contact chip (9), live wire outlet contact chip (11) it is characterized in that: further comprising one and constitutes removable the connection with above-mentioned rotor (7), but and the rotor of synchronous interaction (8), and with this rotor (8) contacted zero line inlet wire contact chip (10), zero line outlet contact chip (12).

2, pulling switch according to claim 1 is characterized in that: be concavo-convex embedded connection between two rotors.
