The push-pull switch of the first embodiment comprises a shell 1 and a push-pull key 4 which is linearly connected with the shell 1 in a moving way, wherein a first electric connecting piece 2 and a second electric connecting piece 3 are fixedly arranged on the shell 1.

Generally, the housing 1 is provided with a linear movement cavity 16, and the push-pull key 4 is attached to the inner wall of the linear movement cavity 16, so that the push-pull key 4 can linearly move along the linear movement cavity 16, and further, the push-pull key 4 is linearly connected with the housing 1.

Preferably, the casing 1 comprises a base 18 and an upper cover 19 detachably connected with the base 18; the top end face and/or the bottom end face of the push-pull key 4 is provided with a bar-shaped protrusion 48 in the linear movement direction (i.e., the direction in which the push-pull key 4 can move linearly along the housing 1), and the bar-shaped protrusion 48 abuts against the upper cover 19. Typically, the cover 19 is snap-fit to the base 18. The upper cover 19 and the base 18 clamp the push-pull key 4 without clearance, so that the push-pull key 4 can be prevented from shaking, meanwhile, the strip-shaped protrusions 48 can reduce the contact area, and smooth linear movement of the push-pull key 4 can be ensured.

Typically, the housing 1 is made of an insulating material such as ABS plastic.

Usually, the first electric connecting piece 2 and the second electric connecting piece 3 are made of conductive materials such as brass. Normally, the first electric connecting piece 2 and the second electric connecting piece 3 are exposed out of the shell 1 so as to be connected with electric wires.

The push-pull key 4 can trigger the first electric connecting piece 2 to bend so that the first electric connecting piece 2 is abutted against the second electric connecting piece 3.

Normally, the first electric connecting piece 2 is provided with a moving projection 219, and the push-pull key 4 is provided with a triggering part 41; the moving protrusion 219 is located on the linear moving path of the trigger 41.

Generally, the first electric piece 2 comprises a moving end 21, the second electric piece 3 comprises a contacted end 31; the push-pull key 4 moves linearly, the trigger part 41 abuts against the moving bulge 219, so that the first electric connecting piece 2 is bent to abut against the second electric connecting piece 3 (the moving end 21 abuts against the contacted end 31), and the first electric connecting piece 2 is electrically connected with the second electric connecting piece 3; at this time, the push-pull key 4 is in a trigger state (not shown in the figure); the push-pull key 4 moves linearly until the first electric connecting piece 2 is bent and reset (usually, the first electric connecting piece 2 has self elasticity), and at the moment, the push-pull key 4 is in a reset state.

The first electric connecting piece 2 is fixedly provided with a reset protrusion 211, the push-pull key 4 is provided with a reset abutting wall 43, and the reset protrusion 211 abuts against the reset abutting wall 43 in the off state to enable the first electric connecting piece 2 to keep the position relative to the second electric connecting piece 3.

Further, the housing 1 is provided with a reset groove 111; the push-pull key 4 is provided with a shift member 42, and in the reset state, the shift member 42 abuts against the inner wall of the reset groove 111, so that the reset abutting wall 43 has a tendency to approach the reset protrusion 211. In the reset state, the reset abutting wall 43 tends to approach the reset protrusion 211, so that the abutting force between the reset protrusion 211 and the reset abutting wall 43 can be improved, and the first electric connecting part 2 and the second electric connecting part 3 can be further ensured to be reliably disconnected.

Preferably, the cross section of the reset groove 111 is generally triangular, the shift member 42 includes a top ball 421, a spring 422 and a shift housing 423, two ends of the spring 422 respectively support the top ball 421 and the shift housing 423, and in the reset state, the top ball 421 supports an inner wall of the reset groove 111, so that the reset support wall 43 tends to approach the reset protrusion 211.
