Detailed Description

The technical solution of the present invention will be described below with reference to the accompanying drawings of the present invention.

The utility model discloses a novel integrated key switch, it includes upper cover 1, base 2, first lug 3, second lug 4 and triggers 5.

The base 2 is provided with an exposed groove 27, the first lug plate 3 and the second lug plate 4 are respectively connected with the base 2 and exposed from the exposed groove 27, and the trigger piece 5 is connected with the upper cover 1 in a translation way. For example, the trigger 5 passes snugly through the upper cover 1, so that the trigger 5 is translatably connected with the upper cover 1.

Preferably, the trigger 5 is fixedly provided with a connecting sheet 51 with conductivity, the connecting sheet 51 faces the first lug 3 and the second lug 4 respectively, and the trigger 5 drives the connecting sheet 51 to translate, so that the connecting sheet 51 is disconnected or connected with the first lug 3 and the second lug 4 respectively, and the first lug 3 and the second lug 4 are connected or disconnected. Generally, the spring 52 provides a repulsive force that can reset the trigger 5.

Preferably, the inner cavity of the trigger 5 is provided with a spring 52, and the spring 52 abuts against the base 2 to keep the connecting sheet 51 separated from the first and

second lugs

3 and 4; to maintain a normally off state between the first and

second tabs

3 and 4.

The upper cover 1 is elastic and is provided with a buckling hole 11; the base 2 is provided with snaps 21, the snaps 21 being respectively snapped into the snap holes 11.

Further, connecting hole 7 has all been seted up to first lug 3, second lug 4, and base 2 is fixed to be provided with spliced pole 28, and first lug 3, second lug 4 are all fixed to be provided with fixed column 6, and fixed chamber 23 has been seted up to base 2, and spliced pole 28 imbeds connecting hole 7 respectively, and fixed column 6 imbeds fixed chamber 23 respectively. The fixing post 6 is typically a copper block riveted to the first or

second terminal lug
