Abstract

The utility model relates to a push button switch, comprising a push rod, a screw thread sleeve, an ejector rod, a tower-shaped spring, a pad sheet, a steel frame, a base, a movable support, an edge end, a middle end, a contact bridge and a spring. The push rod, the ejector rod, the tower-shaped spring and the pad sheet are directly aranged in the screw thread sleeve. The screw thread sleeve and the steel frame are directly riveted together. The edge end and the middle end directly insert into the base by reverse riveting. The contact bridge is supported on the middle end. The spring is sheathed on the movable support and then is placed on the contact bridge. The steel frame is riveted on the base. The steel frame can cooperate with various push buttons at can. The utility model is suitable for various small domestic electrical appliances.

Description

A kind of push-button switch

One, affiliated technical field

The present invention relates to a kind of small household appliances such as fast water heater push-button switch of being used for.

Two, background technology

Be used for reaching the purpose of control circuit and function conversion, the switch of Shi Yonging generally is rocker switch or rocking arm (turning round son) switch or push-button switch in the market.The rocker switch general appearance is bigger, and outward appearance is relatively more traditional.Rocker switch (claim again turn round sub-switch) is though body is less, has been installed on the fast water heater with regard to entire effect the outward appearance of fast water heater, and has been not easy to operation, all should not use on general small household appliances.General push-button switch is to realize on-off function by " the peach heart " technology, and no translation function is added this kind push-button switch processing technology trouble, and switch is when producing in batches, and employee's efficiency of assembling is not high.

Three, utility model content

Task of the present utility model provides a kind of push-button switch, and it can match various buttons arbitrarily, is applicable to various small household appliances.

For finishing above-mentioned task, the utility model has adopted following solution: a kind of push-button switch, comprise push rod, thread bush, push rod, turriform spring, pad, brandreth, pedestal, travel(l)ing rest, limit end, middle-end, contact bridge and spring, push rod, push rod, turriform spring and pad directly are contained in the thread bush, thread bush directly and brandreth rivet together, limit end and middle-end are directly inserted anti-riveting in the pedestal, the contact crane span structure is on middle-end, spring is placed on the contact bridge after being inserted in travel(l)ing rest, and the brandreth riveted is on pedestal.

It has adopted the outward appearance of rocker switch, but does not adopt the structure of rocker switch, and uses the seesaw structure that is equivalent to rocker switch instead, reaches the break-make and the translation function of switch.It has increased the cancellation of the rocking bar of original rocker switch newly push rod, makes it to become a kind of push-button switch.Because this push-button switch can be matched various buttons arbitrarily, therefore, no matter structurally still can both satisfy the requirement of small household appliances such as fast water heater in appearance.

Four, description of drawings

Fig. 1 is the structural representation of present embodiment.

Among the figure: 1, push rod, 2, thread bush, 3, push rod, 4, the turriform spring, 5, pad, 6, brandreth, 7, pedestal, 8, travel(l)ing rest, 9, the limit end, 10, middle-end, 11, contact bridge, 12, spring.

Five, embodiment

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

Referring to Fig. 1, a kind of push-button switch, comprise push rod 1, thread bush 2, push rod 3, turriform spring 4, pad 5, brandreth 6, pedestal 7, travel(l)ing rest 8, limit end 9, middle-end 10, contact bridge 11, spring 12, push rod 1, push rod 3, turriform spring 4 and pad 5 directly are contained in the thread bush 2, thread bush 2 directly and brandreth 6 rivet together, limit end 9 and middle-end 10 are directly inserted anti-riveting in the

pedestal

7,11 of contact bridges are on middle-end 10, spring 12 is placed on the contact bridge 11 after being inserted in travel(l)ing rest 8, and brandreth 6 riveteds are on pedestal 7.

Outside drive push rod 3 actions by pressing push rod 1, push rod 3 makes travel(l)ing rest 8 be in the action that different states drives contact bridge 11 to make switch reach the function of conversion then.Push rod 1 every action of switch once, just conversion is once for the function of switch.

But middle-end 10 and limit end 9 are solder terminal, are used for energized circuit and control circuit.

Claims

1, a kind of push-button switch, comprise push rod (1), thread bush (2), push rod (3), turriform spring (4), pad (5), brandreth (6), pedestal (7), travel(l)ing rest (8), limit end (9), middle-end (10), contact bridge (11), spring (12), it is characterized in that: push rod (1), push rod (3), turriform spring (4) and pad (5) directly are contained in the thread bush (2), thread bush (2) directly and brandreth (6) rivet together, limit end (9) and middle-end (10) are directly inserted anti-riveting in the pedestal (7), contact bridge (11) frame is on middle-end (10), spring (12) is placed on the contact bridge (11) after being inserted in travel(l)ing rest (8), and brandreth (6) riveted is on pedestal (7).

2, a kind of push-button switch according to claim 1 is characterized in that: middle-end (10) and limit end (9) but for solder terminal.
