Description

A kind of microswitch with lamp

Technical field

A kind of microswitch that is used for appliance mains switch, especially a kind of the lid by pendulum makes the inner reed of switch carry out contact separation and closed a kind of microswitch around the strong point.

Background technology

The small-sized microswitch that uses all is by the seesaw of the moving switch inside of pendulum cover tape mostly at present, seesaw is swung realized the folding of contact.The swing type switch of a new generation is to utilize the pendulum lid to rotate, and makes the spring pressurized of pendulum lid below, makes the movable contact spring swing of the contact-carrying that links to each other with spring, realization contact folding, and this swing type switch, it is little to have a volume, the feature that contact resistance is little.But because the contact point of reed and support chip contacts often, so during the reed frequent swing, the contact position easily rubs, and influences the useful life of switch.Moreover this switch is because inner crowded, so contact and contact chip all must be processed very tinyly, therefore the current capacity that can carry is smaller, and if will in this type of switch, neon lamp be installed, must correspondingly increase the inner space, volume of switch is corresponding will to be increased thereby make.The therefore general miniature swing type switch of this class is not with neon lamp.

Summary of the invention

The purpose of this utility model provides a kind of microswitch with lamp, and it can make full use of the switch inner space, increases the cross section of contact and contact chip, to increase its current capacity.The microswitch of this band lamp, comprise on housing that upper shell and base form, the upper shell pendulum lid is housed, the inboard of pendulum lid is provided with spring base, and spring is installed in the spring base, dynamic and static contact is separately fixed on the dynamic and static contact, static contact is fixed on the base, described movable contact spring is the arc reed of middle part bending, and its two arms open, and the one end is compressed by spring, the other end is equipped with moving contact, its bending place is compressed down at spring by they sup-port, and swings around the strong point; Support bar links to each other with the middle haptic element of switch, and the neon lamp of this microswitch is contained in the opposite side of drain pan, and links to each other with lamp base on being fixed on base; This microswitch also can be a kind of double-pole switch, it can cover the inboard at pendulum and be provided with two spring bases, be contained in two springs of this spring base, and compress mutually with the arc reed that is positioned at the switch both sides respectively, the other end of arc reed is equipped with moving contact, it respectively be positioned at base on two static contacts fixed contact from, close, the bending place of arc reed is butted in the groove of support bar, this two support bar with link to each other with second haptic element on the base respectively.The neon lamp of this double-pole switch is installed in the below of pendulum lid, and two lead-in wires of neon lamp are connected in parallel on the two ends of two second haptic elements.The utility model is simple in structure, it replaces traditional reed with the arc reed of bending, the contact site area increases, so it is difficult to wearing and tearing, and has improved the reliability of contact site, owing to the construction of switch that this switch is more traditional is compacter, so the cross section of contact, haptic element can increase, thereby improved its current capacity, simultaneously, save the inner space indication neon lamp can be installed, realized the miniaturization and the slimming of the microswitch of this band lamp.

Embodiment

Fig. 1, Fig. 2, Fig. 3 are first kind of embodiment of the present utility model.Shown in the figure, the housing of having formed switch by upper shell 1 and base 7, moving contact 13 and fixed contact 12, fixed contact 12 is fixed on the static contact 11 of base 7, pendulum covers 2 inboard and is provided with spring base 3, spring 4 is installed in the spring base 3, and an arc reed 5 is arranged in the switch, the middle part bending of this reed, two arms open, one arm end is compressed by spring 4, another arm end is fixed with moving contact 13, and is moving in order to increase, the contact area of fixed contact, an arm that drives the contact preferably bends, moving contact is tilted, its kink is supported by support bar 9, and arc reed 5 can be rotated around this strong point, and support bar links to each other with the middle haptic element 10 of switch.Opposite side at switch is equipped with neon lamp 6, links to each other with haptic element 10 behind the pin series resistor of neon lamp, and the other end links to each other with lamp base 8.During operation, depress the pendulum lid, make spring compress the bow reed, and drive bow reed rotates around the strong point, when spring was in vertical position with the bow reed that is compressed, spring pressurized maximum was passed through the upright position, the bow reed is promoted the position of moving contact and fixed contact is reached " opening " or " closing " state by spring.When the sound closing of contact, haptic element 10 constitutes path with lamp base 8, and neon lamp is bright, otherwise neon lamp does not work.

Fig. 4, Fig. 5, Fig. 6, Fig. 7 are second kind of embodiment of the present utility model.It is the double-pole microswitch of a band lamp.The inboard of pendulum lid is provided with two spring bases 3,3 ', this spring base is positioned at the both sides that pendulum covers 2 belows, spring 4,4 ' is housed respectively in spring base, arc reed 5,5 ' is housed in the switch, its middle part bending, its two arm opens, the one end is compressed mutually by spring 4,4 ' respectively, moving contact 13,13 ' is equipped with in another arm end, it fully contacts in order to make dynamic and static contact with to be contained on the base two fixed contacts 12,12 ' on the static contact 11,11 ' corresponding, in that the crook of the arm folding of moving contact 13 is housed, moving contact is tilted.The bending place, middle part of arc reed is against respectively on the support chip 9,9 ', and this support chip has depression, and the middle part kink of bow reed is against in this depression, locatees in order to the bow reed.Support chip 9,9 ' is connected with haptic element 10,10 ' respectively, and the neon lamp accumbency is connected in parallel on behind the two pin series resistors of neon lamp on the haptic element 10,10 ' below pendulum lid.During operation, depress pendulum lid and make two springs compress the bow reed respectively, drive the bow reed and rotate around the depression of support chip, spring compresses the bow reed, makes the position of two pairs of moving contacts and fixed contact reach " opening " or " closing " state.When two pairs of closings of contact, haptic element 11,11 ' and haptic element 10,10 ' constitute path, neon lamp is bright, on the contrary neon lamp does not work.
