Abstract

A switch of key type consists of key cover, base, containing frame and reset mechanism. It is featured as setting reset mechanism in containing frame between key cover and base; pressing down key cover to let reset mechanism coordinate slide block , link rod ,reset spring , etc for turning over switch contact alternatively; and restoring switch to be initial position when key cover is released.

Description

technical field [0001] The invention relates to a key switch, in particular to a civil key switch with an automatic reset mechanism. Background technique [0002] Push-button switch is the most common and common electrical component used to control the on-off of electrical equipment. The ordinary push-button switch is a double-position type. Keeping it in different positions, it is common that the height of the same end is different, which makes the overall appearance of the switch uneven, with a low overall sense and poor fluency. figure 1 Shown is a common manual push-type switch, which includes a key cover 1 and a base 7, a terminal 71 is provided in the base, a rocker 5 is provided between the base 7 and the key cover 1, and a spring is provided in the rocker , the position of the rocker is in the slideway inside the button cover, forming a T-shaped structure with the button. In the initial state, the rocker is located on one side of the seesaw 6, and when the key cove...
