ROCKER KEY WITH LED WINDOW

Abstract

A rocker key with a LED window has a lower perimeter rim with a rectangular section, a cover that is fitted on top of the key and is left with its lower edge resting totally on a flat upper surface of the perimeter rim, while a vertical outer surface of the lower perimeter rim which is elevated according to a normal rocking movement is uncovered and visible from outside.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

In accordance with the drawings, the rocker key (1) provided with a LED window (2) has a lower perimeter rim (3) with a rectangular section.

This rim is interrupted on two of its sides, by a notch (4), in the place coinciding with the retaining projection (5) that the key (1) has on the two same sides.

From the lower face of the key (1) two protrusions (6) emerge that allow it to be fixed on to the appropriate rocker arm (7) of the electrical mechanism (8), after positioning the key (1) in the corresponding window (9) of the base plate (10).

The cover (11) that is fitted on top of the key (1) is left with its lower edge resting totally on the flat upper face (3a) of the perimeter rim (3) of the key (1).

With the cover (11) thus installed, its chromatic aspect will be visible, in addition to the chromatic finish of the vertical outer face (3b) of the abovementioned perimeter rim (3), identical to that of the key (1), meaning that the user will be able to perceive two different-coloured elements: the cover (11) and the outer face (3b) of the rim (3) of the key (1).

Given the transparency of the cover (1), the luminosity transmitted through the window (2) of the key (1) confers on the upper surface of the entire cover (11) sufficient light for it to be signposted or located.

The cover (11) has inside its two side faces, respective rectangular grooves (12) coinciding in their position with the retaining projections (5) of the key (1) in such a way that when the cover (11) is fitted on the key (1), it will hook onto it through pressure and remain fixed by the action of the projections (5) slotting into the grooves (12).

The notches (4) of the rim (3) allow, with the use of the appropriate tool, the projections (5) to be acted on so as to release the cover (11) easily.

In the embodiment with the two half-module keys (1a) the covers (11a) must have the right size but attach to the key in an identical manner.

Having sufficiently described the object of this invention, it is noted that its essential nature will not be altered by variations in size, shapes, materials or finishes, as described in the following claims.

Claims

1. Rocker key with LED window and chromatic cover for actuating electrical mechanisms, characterised in that it comprises a lower perimeter rim (3) with a rectangular section, on the upper and horizontal flat face of which (3a) the cover (11) rests entirely, fitted through pressure on the key (1) in such a way that the key (1) is totally covered by said cover (11), while uncovered and visible from the outside is the vertical outer face (3b) of the lower perimeter rim (3) of the key (1), which is elevated according to its normal rocking movement.

2. Rocker key with LED window and chromatic cover for actuating electrical mechanisms, according to claim 1, characterised in that the perimeter rim (3) is interrupted on two of the opposite sides of the key (1) by relevant notches (4) on which and in the corresponding outer faces of the vertical walls of the key (1) are situated retaining projections (5) on which, when the cover (11) is fitted onto the key (1) rectangular grooves (12) are positioned that the cover (11) has, meaning that it will become hooked over the projections (5) and fixed to the key (1), allowing the notches to act on the projections (5) to liberate the cover (11) from its fitted position.

3. Rocker key with LED window and chromatic cover for actuating electrical mechanisms, according to claim 1, characterised in that the cover (11), made of a transparent material and with a different chromatic finish to that of the key (1), on fitting over it, will make visible throughout its entire upper surface the light transmitted through the window (2) of the key (1), allowing it to be signposted or located, completed with the chromatic view of the outer vertical wall (3b) of the rim (3), normally different to the cover.

4. Rocker key with LED window and chromatic cover for actuating electrical mechanisms, according to claim 1, characterised in that it presents, as a variation, two half-module keys (1a) for actuating two distinct electrical mechanisms (8), on which the right-sized covers (11) will be fitted, fixed in an identical manner and with identical characteristics, keys that, like key (1) are positioned in the window (9) of the base plate (10).
