The utility model discloses the task realizes through following technical scheme:

the utility model provides an electron dabs switch, includes back seat, circuit board, frame and the keypad that sets gradually, it holds the chamber to form one between back seat and the frame, the circuit board is the individual layer circuit board and installs in holding the intracavity, keypad installs the surface at the frame, the front of circuit board is equipped with at least one lamp position, each all be equipped with a plurality of lamp pearls on the lamp position, the position that corresponds each lamp position on the frame is equipped with a through-hole respectively, the area of through-hole is greater than and corresponds the lamp position, the last position that corresponds the through-hole of keypad is equipped with the printing opacity character, thereby the light that the lamp pearl sent can shine the character through-hole and form the character effect in a poor light on keypad on the character.

As a preferred technical scheme, a plurality of binding posts are arranged on the back surface of the circuit board, and the binding posts are iron sleeves welded on the circuit board.

As the preferred technical scheme, the lamp beads are bicolor lamp beads or monochromatic lamp beads.

As a preferred technical scheme, the through hole is a large square hole.

The utility model provides a pair of electron dabs switch has following advantage: (1) the single-layer circuit board is adopted, the lamp positions arranged on the circuit board are larger in area by reasonable layout on the single-layer circuit board, a plurality of lamp beads (or double-color lamp beads) can be arranged, a large square hole is arranged on the outer frame corresponding to the lamp positions, the key panel is provided with light-transmitting characters, light emitted by a plurality of lamp beads on the lamp positions of the circuit board irradiates the characters on the key panel through the large square hole, and therefore the light-transmitting character effect is formed on the front side of the key panel; (2) the copper column of welding on traditional electrician's product electron type dabs the switch circuit board, and the copper column price is more expensive, adopts the iron cover welding in this patent, can satisfy the wiring requirement, again than copper column price low price.

The conception, the specific structure and the effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.
