Abstract

The utility model relates to an improved domestic circuit see-saw switch, which is mainly characterized in that a support frame replaces copper tubing grains which are primely arranged on the center of inner bottom of a subbase. The support frame is made of the copper sheet whose two ends tuck upwards to support the see-saw switch. The support frame is fastened to the inner bottom of the subbase. Hence, nutation of the power cords which are connected with terminals at the center of outer bottom of the subbase can not bring movement of the support frame, which improves stabilisation and reliability of the switch.

Description

Domestic circuit see-saw switch

The utility model relates to the improvement to existing a kind of rocker switch.

At present, the control of bright lamp is quite general in contrast to adopt rocker switch in the domestic circuit.This switch has action characteristics clear-cut, easy to use, is liked by people deeply.For this reason, vast producer competitively develops.But for many years, producer adopts following structure always.

This rocker switch, its technical pattern feature is as follows:

1) base outer bottom centre has a step, is fixed with binding post in the both sides of step;

2) base inner bottom part both sides are fixed with the contact, and the contact is electrically connected with corresponding binding post;

3) base inner bottom part centre crouches and puts a copper pipe grain, and it does not take place directly to contact with two contacts;

4) seesaw is cross-like shape, is positioned on the above-mentioned copper pipe grain, and it is relative that its both ends and above-mentioned two contacts form, and its two sides extension then sinks into the groove of the inner both sides of base;

5) button, its back side centre has a center tubing string, its built-in spring;

6) steel ball between above-mentioned spring and seesaw, is used to regulate seesaw and is inclined to an end or the other end;

7) all inner parts all are fixed in back side of panel by base, and are blocked by panel by the flange that the button both sides form and be packaged in base inside.

When this switch used, power line was to be fixed in the copper pipe grain by base outside side opening, and electrical appliance circuit one end then is fixed in the arbitrary binding post in above-mentioned two binding posts.By the moving button of plate, can control seesaw and contact with a certain contact or break away from, thereby reach control to illuminalive power-supply.

In case the weak point of this switch is that power line is affected and all can causes moving of copper pipe grain, influence the stability of copper pipe grain, might make certain in a flash seesaw break away from contact, it is insecure to cause moment to contact.

The purpose of this utility model is to overcome above-mentioned deficiency and a kind of improved rocker switch is provided, the problem that the stability that it can solve above-mentioned seesaw is effectively affected by power line to influence, thus help improving better the reliability of switch.

Improved part relates generally to the copper pipe grain, this programme is abandoned it, replace is that centre at the base outer bottom is fixed a binding post again, be used to be connected and fixed power line, the centre of base inner bottom part is then fixed a support, this support is made by a copper sheet, upwards turn up at the both ends of this copper sheet, simultaneously, this support also forms with the binding post of base outer bottom centre and is electrically connected, at this moment, seesaw two side extensions then are that groove by the inner both sides of base is positioned at the part place that copper sheet is upwards turned up.

The utility model will can not cause moving of support because the support of support seesaw is to be fixed in base inner bottom part place, and the electric wire that is connected in base outer bottom centre binding post like this affects, thereby help improving better the reliability of switch.Simultaneously, support is fixed in the base inner bottom part earlier and also will makes more or less freely the carrying out of switch assembling.

Fig. 1 is the rearview of a kind of concrete switch of the utility model;

Fig. 2 be Fig. 1 along A-A to view;

Fig. 3 is the copper sheet schematic diagram of Fig. 2 support;

Fig. 4, Fig. 5 are the copper sheet schematic diagram of another kind of support.

The utility model is described in further detail below in conjunction with accompanying drawing:

With reference to the rocker switch shown in the accompanying drawing 2, comprise button 1, spring 2, steel ball 3, seesaw 4, support 6, contact (5a, 5b), binding post (8a, 8b), central authorities' binding post 7, base 9 and panel 10, wherein, support 6 is fixed in the inner bottom part of base 9 by screw, screw also is fixed in central binding post 7 the outer bottom centre of base 9 simultaneously, this connection not only makes support 6 and central binding post 7 be fixed, but also being formed, they are electrically connected, has characteristic of simple structure, 4 parts of stretching out by its two side of seesaw are supported in support 6 and upwards turn up part, move by the moving button 1 may command steel ball 3 of plate, thereby make an end of seesaw 4 break away from corresponding contact, the other end contacts another contact, reaches break-make control.

In the foregoing description, support 6 is to make (with reference to shown in Figure 3) by the copper sheet of both ends shape triangular in shape, and upwards turn up at the both ends of this copper sheet, and it turns up the fulcrum of two wedge angles of part as seesaw 4.

In the foregoing description, support 6 also can be made (with reference to shown in Figure 4) by the copper sheet of a both ends semicircular in shape shape, and upwards turn up at the both ends of this copper sheet, and it turns up the fulcrum of the dome of part as seesaw 4.

In the foregoing description, support 6 also can be made (with reference to Fig. 5) by a copper sheet that is rectangular bar shaped, and upwards turn up at the both ends of this copper sheet, and its top of turning up is along the fulcrum as seesaw 4, when adopting this way, arc is preferably made in its cross section of part that stretch out seesaw 4 both sides.

According to above design, can make many kinds of conversion equally to support 6 and seesaw 4, but all belong to the application's scope undoubtedly.
