Abstract

The utility model discloses a miniature slide switch which can bear higher current and has more reliable use. The miniature slide switch comprises a base, a cover plate arranged on the base, a toggle arranged at the opening part of the cover plate, a central terminal and a fixed terminal arranged on the bottom plate of the base, and a movable contact piece arranged on the central terminal, wherein a moving contact is arranged at the end part of the movable contact piece, a stationary contact is arranged on the fixed terminal corresponding to the moving contact, a spring hole is formed at the lower part of the toggle, a spring and a sliding pin are arranged in the spring hole, and the extending end of the sliding pin is held against the upper surface of the movable contact piece. The utility model has the advantages that the switch utilizes the separation and combination of the moving contact and the stationary contact to switch the make-and-break of the circuit, and the contact points enable the contact to be tighter and more reliable due to the acting force from the spring, therefore, the miniature slide switch can bear higher passing current.

Description

Micro slide switch

Technical field

The utility model relates to a kind of switching device that is used to be switched on or switched off circuit, relates in particular to a kind of miniature slidingtype mains switch that can bear big electric current.

Background technology

Traditional micro slide switch comprises pedestal, be arranged on the cover plate above the pedestal, be arranged on the toggle of cover plate oral area, be arranged on center terminal and fixed terminal on the pedestal bottom plate, be arranged on the movable contact spring on center terminal and the fixed terminal, movable contact spring is arranged in the groove of toggle bottom, can drive movable contact spring and moves between center terminal and fixed terminal by stirring toggle, can realize switching on and off of slide switch.When this micro slide switch uses, handle toggle left and right sides translation, drive the movable contact spring rectilinear motion, the slide displacement relative with generation between terminal realized connection and cut-out between center terminal and the fixed terminal.This micro slide switch does not generally all have the contact, and the thickness of movable contact spring is generally 0.2 millimeter, so it can not bear bigger electric current, load current value is generally 0.2 peace, can not use as mains switch, can only use as signaling switch at most.

The utility model content

The purpose of this utility model is to provide a kind of and can bears big electric current and use more reliable micro slide switch.

For realizing the purpose of this utility model, a kind of micro slide switch, comprise pedestal, be arranged on the cover plate above the pedestal, be arranged on the toggle of cover plate oral area, be arranged on center terminal and fixed terminal on the pedestal bottom plate, be arranged on the movable contact spring on the center terminal, described movable contact spring end is provided with moving contact, be provided with fixed contact with the corresponding fixed terminal of moving contact, the bottom of toggle offers spring eye, is provided with spring and sliding pin in the spring eye, and the external part of sliding pin is against the upper surface of movable contact spring.

The beneficial effects of the utility model are: switching on and off of the incompatible commutation circuit of branch between this switch dependence moving contact and the fixed contact, owing to be subjected to the active force of spring, make contact more tight and reliable between the contact, and therefore can bear passing through of big electric current; Simultaneously,, therefore also can further guarantee the arc resistance and the resistance to wear of switch, thereby touch the normal use of protecting switch because dynamic and static contact adopts the silver alloy of good conductivity to make mostly.

Embodiment

Below in conjunction with accompanying drawing, the structure and the operation principle of the utility model micro slide switch is described in further detail.

As illustrated in fig. 1 and 2, a kind of micro slide switch, comprise: pedestal 1, be arranged on the cover plate 2 above the pedestal 1, be arranged on the toggle 3 of cover plate 2 oral areas, be arranged on center terminal 4 and fixed terminal 5 on pedestal 1 base plate, be arranged on the movable contact spring 6 on the center terminal 4, described movable contact spring 6 ends are provided with moving contact 7, be provided with fixed contact 8 with moving contact 7 corresponding fixed terminals 5, the bottom of toggle 3 offers spring eye 9, is provided with spring 10 and sliding pin 11 in the spring eye 9, and the external part of sliding pin 11 is against the upper surface of movable contact spring 6.Can swing reliably on center terminal 4 in order to ensure movable contact spring 6; usually can be provided with limited bayonet at the top of center terminal 4; movable contact spring 6 middle parts are provided with location notch, and by location notch and bayonet fittings, movable contact spring 6 can be swung around center terminal 4 more reliably.

Operation principle of the present utility model is: when this slide switch uses, make toggle 3 side-to-side movements, spring 10 of toggle 3 drive its underparts and sliding pin 11 are in the upper surface slide of movable contact spring 6, movable contact spring 6 is swung around center terminal 4, engage and the action that separates thereby make to produce between moving contact 7 and the fixed contact 8, make switch realize more reliable on-off.

Claims

1. micro slide switch, comprise pedestal, be arranged on the cover plate above the pedestal, be arranged on the toggle of cover plate oral area, be arranged on center terminal and fixed terminal on the pedestal bottom plate, be arranged on the movable contact spring on the center terminal, it is characterized in that: described movable contact spring end is provided with moving contact, is provided with fixed contact with the corresponding fixed terminal of moving contact, and the bottom of toggle offers spring eye, be provided with spring and sliding pin in the spring eye, the external part of sliding pin is against the upper surface of movable contact spring.
