Abstract

The invention relates to a toggle switch. A toggle switch generally includes a base, a central terminal and a fixed terminal arranged at the bottom of the base, and a movable contact piece horizontally arranged in the base. The switch uses the upper end of the central terminal as a support for the seesaw movement of the movable contact piece to realize the clutch between the movable contact piece and the fixed terminal, and then realizes the on-off of the switch. When the traditional toggle switch is subjected to abnormal external force, the movable contact piece is easy to slip off from the upper end of the central terminal, causing the switch to fail. The toggle switch of the present invention is formed with an extension on the upper end of the central terminal to block the movable contact piece. Buckling the moving contact piece makes it difficult for the moving contact piece to slip off when the switch is subjected to abnormal external force, which improves the quality and stability of the switch and has great practical value.

Description

A kind of tumbler switch

Technical field

The present invention relates to be used for the mains switch of on-off circuit, be specifically related to a kind of tumble power switch

Background technology

are as shown in Figure 1; Traditional tumbler switch generally includes pedestal (1 '), be arranged on pedestal (1 ') bottom center terminal (2 ') and fixed terminal (3 '), be horizontally set on movable contact spring (4 ') on the center terminal (2 '), be arranged on the moving contact (5 ') of movable contact spring (4 ') end and be arranged on the fixed terminal (3 ') and with the corresponding fixed contact of moving contact (5 ') (6 '); Pedestal (1 ') upper oral part is provided with toggle (9 '); Offer the spring cavity that Open Side Down in the toggle (9 '); Be provided with spring (8 ') and sliding pin (7 ') in the spring cavity, an end that stretches out spring cavity of sliding pin (7 ') and the surface of movable contact spring (4 ') offset.The operation principle of above-mentioned tumbler switch is: stir toggle (9 '); It serve as that " seesaw motion " done in support with the upper end of center terminal (2 ') that toggle (9 ') drives movable contact spring (4 ') through spring (8 ') and sliding pin (7 '); Make moving contact (5 ') realize contact and separate, and then realize the break-make of power supply with fixed contact (6 ').The structure of the center terminal (2 ') of this conventional toggle switch is shown in Fig. 2 and 3; The upper end of center terminal (2 ') is the design of " recessed " font; Length direction along center terminal (2 ') extends to form a pair of convex shoulder (21 '), and movable contact spring (4 ') promptly is fastened between this a pair of convex shoulder (21 ') of center terminal (2 ') upper end.Flexible for guaranteeing switch; Must leave certain clearance between movable contact spring (4 ') and the convex shoulder (21 '); Therefore; In use when receiving unusual external force or having the vibratory impulse phenomenon, movable contact spring (4 ') is easy to " recessed " font upper end slippage from center terminal (2 ') to switch, causes switch failure

Summary of the invention

technical problem to be solved by this invention is the deficiency that overcomes prior art, provides a kind of improved stability better tumbler switch.

For solving above technical problem, the technical scheme that the present invention takes is:

a kind of tumbler switch; The contact site that comprises pedestal, is arranged on the press section on the pedestal, the first terminal that is fixedly installed on base bottom and second terminal, is horizontally set in the said pedestal and flexibly connects mutually with the upper end of the first terminal and be arranged on the press section and contact site between elastic component; When switch is in closure state; The conducting that contacts with second terminal of the end of contact site; When switch was in off-state, the end of contact site and second terminal were separated, a pair of convex shoulder that the first terminal comprises that terminal body, lower end are fixedly installed on the terminal body and extends along the length direction of said the first terminal; Also comprise by the bending of the upper end of convex shoulder and extend to form be blocked in the extension on the said contact site, this extension makes contact site be difficult to the upper end slippage from the first terminal.

preferably, the both sides of contact site offer a pair of bayonet socket of symmetrical setting, convex shoulder and contact site are in the clamping mutually of the position of this a pair of bayonet socket.

according to the present invention, said elastic component is preferably spring.

preferably, said switch also comprises along the bearing of trend of contact site and is slidingly arranged in the sliding pin on the contact site, the upper end of elastic component connects the press section, the lower end of elastic component is connected with sliding pin.The setting of sliding pin be more convenient for the contact of people through elastic component control contact site and second terminal with separate, make switch motion sensitiveer.

Through the enforcement of above technical scheme, make the present invention compared with prior art have plurality of advantages:

tumbler switch of the present invention is owing to be formed with the extension that is blocked on the contact site in the upper end of the first terminal, makes switch contact site when receiving unusual external force or jerk be difficult for slippage from the first terminal, and switch stability is better.
