Abstract

The utility model discloses a three-way toggle switch, and the main points of the utility model are that the switch comprises a pedestal made of insulating materials, a cover plate, and a spherical twisted handle. The bottom surface of the pedestal is fixedly equipped with three binding posts, one of which is located between the other two binding posts. The top of the three binding posts is provided with a V-shaped rocker made of conductor materials. One end of the spherical twisted handle passes through the top of the cover plate and the other end of the spherical twisted handle is provided with a pin which contacts with the V-shaped rocker. A part, which contacts with the binding posts, of two ends of the V-shaped rocker is bent into an arc shape. The V-shaped rocker contacts with the binding posts in a manner of line contact. According to the utility model, the structural design of the V-shaped rocker is improved so as to enable the rocker to contact with the binding posts in a manner of line contact, and this manner of line contact lies between point contact and surface contact, so that not only a defect of unstable contact caused by the point contact, but also a defect that a contact portion is binding together caused by the surface contact, is overcome.

Description

The third gear toggle switch

Technical field

The utility model relates to a kind of electrocomponent technology field, and more particularly, it relates to a kind of third gear toggle switch.

Background technology

Toggle switch is a kind of hand control switch, and the break-make that is mainly used in the alterating and direct current source circuit is controlled, but generally also can be used for several kilo hertzs or up to the circuit of 1 megahertz.Have volume little, the characteristics such as easy to operate are switches commonly used in electronic equipment.When manual operation, switch motion can be divided into three phases.Phase I is to turn round handle in the centre position, this moment, extraneous two circuit all were in off state, second stage is turned round handle and is crossed the backward end in upright position and pull and be in an end, this moment, a circuit was connected, three phases, turn round handle and pull to an other end that original circuit of connecting disconnects when turning round handle and get back to the upright position, continue to pull when turning round handle and arriving the other end, the another one circuit is connected.

At present, to contact with binding post be form contact with a contact for common two kinds of third gear toggle switchs on market, a kind of third gear toggle switch, seesaw.To comprise the base plate of being made by insulating material, seesaw, turn round handle, be fixed with binding post on base plate, the part that the seesaw two ends contact with binding post is a hemisphere, the design of this seesaw structure make seesaw with binding post with a contact that contacts, it is extremely unstable that the mode of this some contact can cause seesaw to contact with binding post.Another third gear toggle switch, it is the form contact that contacts with face that seesaw contacts with binding post, the part that the seesaw two ends contact with binding post is a circular face, the structural improvement of this seesaw, seesaw contacts with the wiring cylinder, although a kind of third gear toggle switch before having overcome, seesaw causes the unsettled defective of contact with binding post with the form that a contacts contact, but can cause seesaw and binding post to be bonded together because of the heat that produces during contact after of long duration, circuit be difficult for disconnecting.

The utility model content

Deficiency for the prior art existence, the purpose of this utility model is to provide a kind of third gear toggle switch, this third gear toggle switch has improved the structural design of seesaw, the form contact that makes seesaw and binding post contact with line, this way of contact is between a contact and face contact, not only overcome because a contact causes the unsettled defective of contact, also overcome the defective that the face contact causes contact portion to be bonded together.

for achieving the above object, the utility model provides following technical scheme: a kind of third gear toggle switch, comprise the pedestal of being made by insulating material, cover plate, sphere is turned round handle, fix respectively three binding posts on base bottom surface, one of them binding post is positioned at the centre of two other binding post, the V-arrangement seesaw that a conductive material is made is set above three binding posts, the end that sphere is turned round handle passes the cover plate top, the other end is provided with pin, pin contacts with the V-arrangement seesaw, the position bending that the two ends of described V-arrangement seesaw contact with binding post is a circular shape, described V-arrangement seesaw contacts with the form that line contacts with binding post.

By adopting technique scheme, improve the structural design of V seesaw, the position bending that the two ends of V-arrangement seesaw are contacted with binding post is a circular shape, the form contact that makes V seesaw and binding post contact with face, overcome because a contact causes the unsettled defective of contact, also overcome the defective that the face contact causes contact portion to be bonded together.

The utility model further is set to: described sphere is turned round handle one end and is provided with the elongated slot that coordinates with pin, and described pin socket connection is provided with spring in described pin and elongated slot at the end in elongated slot.

By adopting technique scheme, be provided with spring in pin and elongated slot at the end, can further improve the reliability that seesaw contacts with binding post.

The utility model further is set to: described base and cover plate connects by dismountable mode.

Embodiment

With reference to Fig. 2 to Fig. 3, the utility model third gear toggle switch embodiment is described further.

the utility model provides following technical scheme: a kind of third gear toggle switch, comprise the pedestal 1 of being made by insulating material, cover plate 3, sphere is turned round handle 4, fix respectively three binding posts 5 on pedestal 1 bottom surface, 6, 7, one of them binding post 6 is positioned at two other binding

post

5, 7 centre, three

binding posts

5, 6, 7 tops arrange the V-arrangement seesaw 2 that a conductive material is made, the end that sphere is turned round handle 4 passes cover plate 3 tops, the other end is provided with pin 41, pin 41 contacts with V-arrangement seesaw 2, the two ends of described V-arrangement seesaw 2 and binding post 5, the position bending of 7 contacts is a circular shape, described V-arrangement seesaw 2 and binding post 5, the 7 form contacts with the face contact.By adopting technique scheme, improve the structural design of V seesaw 2, the position that the two ends of V-arrangement seesaw 2 contacts with binding
