Abstract

Disclosed is an open type dual-button controlled pushbutton switch, which is composed of a button, return springs, contact components and a socket. One side of the socket is clamped with a connecting plate riveted with two static contacts, two slots on the other side of the socket is fixed with a U-shaped plate riveted with static contacts by screws, and the bottom is plugged with a movable clamping board. Two contact supports extend out of an iron fixing plate, a contact bridge whose both ends are riveted with moving contacts is plugged in each contact support, and a supported spring is placed on the contact bridge. The return spring is sheathed outside the contact support which is covered by a water-proof rubber soft cover and fixed by shims. The end part of the contact support is provided with a button, wherein, the lower part of the contact support serving as ON is provided with a clamping groove. A shaft with a pin torsion spring is arranged in the socket, one end of the pin torsion spring is extended out of one hole in the middle of the movable clamping board, and the iron fixing plate is positioned on the socket. The utility model has reliable contact, flexible operation, and long service life. The utility model can be widely used as circuital ON-OFF control in the electric control circuit.

Description

Open type dispireme control button switch

One, affiliated technical field

The utility model relates to a kind of push-button switch, refers in particular to a kind of open type dispireme push-button switch.

Two, background technology

Push-button switch can be classified by mode of operation, protection mode, and open type wherein is applicable to that setting-in is fixed on the panel of switchboard, control cubicle or control desk; Press the needs of control loop, be divided into single button, dispireme, three buttons and many buttons.Control generally all is made up of button, back-moving spring, contact, shell and support coupling part with the structure of button, makes standard cell usually.At present, open type dispireme control button switch commonly used is owing to exist structural defect, causes that contact reliability is poor, operating flexibility is bad, and useful life is short.

Three, utility model content

The purpose of this utility model is to provide a kind of open type dispireme control button switch, reliable, the flexible operation of its contact, and long service life can be widely used in the electric control circuit ON-OFF control as circuit.

For achieving the above object, the solution that the utility model is taked is: a kind of open type dispireme control button switch, by button, back-moving spring, contact assembly, base is formed, base one side card has riveting that the connecting plate of two fixed contacts is arranged, be screwed the U template that riveting has fixed contact in two grooves of opposite side, the bottom is inserted with movable clamp, two contact supports stretch out the irony fixed head, be inserted with the two ends riveting in each contact support the bridge that touches of moving contact is arranged, touch to place on the bridge and support spring, cover the soft cover of water proof rubber again by spacers behind the support overcoat back-moving spring of contact, support end, contact is provided with button, wherein the support lower part, contact as ON has a draw-in groove, in base, place the axle of band pinned torsional spring, pinned torsional spring one end stretches out the middle hole of movable clamp, and the irony fixed head is placed on the base.

The utility model can be fixed on the panel of switchboard, control cubicle or control desk by setting-in, is widely used in the electric control circuit ON-OFF control as circuit.Press as the button on the contact support of ON (button Face has the ON sign), overcome the effect of back-moving spring, owing to have a draw-in groove as the support lower part, contact of ON, this draw-in groove is stuck in movable clamp, and contact is reliable, and circuit is connected.When the button of pressing on another contact support (button Face has the OFF sign), overcome the effect of back-moving spring, support lower part, contact makes movable clamp slide off draw-in groove as the support lower part, contact of ON, under the effect of back-moving spring, resets as the contact support of ON.Unclamp the button on another contact support, under the effect of back-moving spring, another contact support resets, and at this moment circuit disconnects.Its flexible operation.Since adopt the irony fixed head, not yielding, long service life.

Fig. 1 is the upward view of present embodiment.

Fig. 2 is the front view of present embodiment.

Fig. 3 is the vertical view of present embodiment.

Fig. 4 is the A-A cutaway view of Fig. 1.

Among the figure: 1, button, 2, the soft cover of water proof rubber, 3, touch bridge, 4, moving contact, 5, the irony fixed head, 6, base, 7, connecting plate, 8, movable clamp, 9, fixed contact, 10, screw, 11, the U template, 12, fixed contact, 13, moving contact, 14, pad, 16, back-moving spring, 17, contact support, 18, support spring.

Five, embodiment

Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.

Referring to Fig. 1-Fig. 4, a kind of open type dispireme control button switch, by button 1, back-moving spring 16, contact assembly, base 6 is formed, base 6 one side cards have riveting that the connecting plate 7 of two fixed contacts 9 is arranged, in two grooves of opposite side with screw 10 fixedly riveting the U template 11 of fixed contact 12 is arranged, the bottom is inserted with movable clamp 8, two contact supports 17 stretch out irony fixed head 5, be inserted with the two ends riveting in each contact support 17 moving contact 4 is arranged, 13 touch bridge 3, touch to place on the bridge 3 and support spring 18, it is fixing by pad 14 to cover the soft cover 2 of water proof rubber behind the contact support 17 overcoat back-moving springs 16 again, support 17 ends in contact are provided with button 1, wherein contact support 17 lower parts as ON have a draw-in groove, in base 6, place the axle of band pinned torsional spring, pinned torsional spring one end stretches out movable clamp 8 middle holes, and irony fixed head 5 is placed on the base 6.

Referring to Fig. 2, irony fixed head 5 has two holes, has two protruding holes to cooperate with two holes on the irony fixed head 8 just above the base 6.Like this, after the installation, be difficult for sliding, help improving the reliability of contact.

Referring to Fig. 1 and Fig. 2, connecting plate 7 one ends stretch out longer, are convenient to be connected with contiguous open type dispireme direction switching button switch.

Referring to Fig. 4,5 liang of irony fixed heads are little sticking up along the limit, both improved intensity, is convenient to again install.
