Abstract

The invention discloses a micro-moving position-limiting general switch, which comprises a housing. The housing is provided therein with a normally open insertion component whose one end extends out of the housing, a normally closed insertion component and a common insertion component. The housing is also provided with a moveable contact sheet in electrical connection with the common insertion component, arranged between the static contact points of the normally open insertion component and the normally closed insertion component for switched communications and a direction guiding component used to limit the moving trajectory of the moveable contact sheet. The moveable contact sheet is connected in sequence with an elastic component and a trigger component that produce the elastic force to drive the moveable contact sheet to move. The elastic component is provided with an arc contact surface in contact with the inclined surface of the direction guiding component. According to the invention, the micro-moving position-limiting general switch adopts an elastic component to serve as the drive of the switch by producing elastic force to realize the switching of the switch, and during the switching process, downward pressure generated between the arc contact surface and the inclined surface of the direction guiding component acts on the moveable contact sheet, which avoids the occurrence of force balance by the moveable contact sheet from the transient time jumping from the normal open to the normal closed or from the normal closed to the normal open, which leads to the micro-moving and the flashing or power-off of the switch.

Description

technical field [0001] The invention relates to a switch, in particular to a universal switch with micro-motion limit. Background technique [0002] The micro switch is a contact mechanism with a small contact interval and a quick-action mechanism, which performs switching actions with a specified stroke and a specified force. It is covered with a casing and has a trigger rod on the outside. Small, hence the name micro switch. The external mechanical force acts on the action reed through the transmission element (press pin, button, lever, roller, etc.). Click on or off quickly. When the force on the transmission element is removed, the action reed produces a reverse action force, and when the reverse stroke of the transmission element reaches the action critical point of the reed, the reverse action is completed instantaneously. The contact spacing of the micro switch is small, the action stroke is short, the pressing force is small, and the on-off is rapid. The action s...
