, Description:Field of the invention

The present invention relates to a lighting switch and more particularly, to a switching assembly of a flush switch.

Background of the invention

Light switches are designed majorly for final distribution of electricity at the standard distribution rating of 240V- 20A in applications of switching ON/OFF state of electrical appliances. In residential and light commercial lighting systems, the light switch directly controls the circuit feeding of the appliances. In larger lighting systems, for example, warehouses or outdoor lighting systems, the required current may be too high for a manual switch. In these systems light switches control lighting contactors, a relay that allows the manual light switch to operate on a lower voltage or with smaller wiring than would be required in the main lighting circuit. Light switches known in the art are classified on the basis of their design and switching mechanism as a push button, toggle button, rocker button and the like. Most of the switches know till date are known to protrude out from a module plate. The prior art fails to disclose any switches which stay flushed and can be operated effectively in making and breaking supply along with providing a better aesthetic appeal to the user.

Accordingly, there is a need for mechanism which suffices to the flush form of the switches without hampering on the mechanical life.

Objects of the invention

An object of the present invention is to convert a conventional toggle mechanism into a linear one with a help of a slidably coupling.

Another object of the present invention is to ensure that the switch remains flushed or flat in both its ON-OFF operation.

Yet another object of the present invention is to provide a mechanism which suffices to the flush form of the switches without hampering on the mechanical life.

Summary of the invention

Accordingly, the present invention provides a slider switch assembly for a flush switch. The slider switch assembly comprises a housing, a toggle, a slider and a top cover. The housing encloses a fixed contact to be detachably coupled with a moving contact configured at a bottom portion of the slider switch assembly. The housing also comprises a spring loaded plunger configured centrally therein. The toggle has one end that engages with the moving contact and a central portion that engages within the spring loaded plunger. The slider includes a coupler on a bottom portion which couples another end of the toggle therein. A middle portion of the slider is slidably configured on a holder plate. The top cover has a central slit aperture for accommodating a top grip portion of the slider therein. The top cover engages with the housing to form an outer cover.

Further, when a user pushes the slider from one operational OFF state, the sliding motion of the slider enables the coupler to move the toggle along. The toggle expands the spring loaded plunger allowing it to attain a stable state in an alternate direction. The toggle thereby crosses a toggle point / dead centre which then enable the moving contact to move down pressing against the fixed contact completing the circuit to switch in an ON operational state.

Detailed description of the invention

The foregoing objects of the present invention are accomplished and the problems and shortcomings associated with the prior art, techniques and approaches are overcome by the present invention as described below in the preferred embodiment.

The present invention provides a slider switch assembly for a flush switch. The slider switch assembly comprises a housing, a toggle, a slider and a top cover. The mechanism of the present invention enables the flush form of the switches without hampering on the mechanical life. The present invention ensures that the switch remains flushed or flat in both its ON-OFF operation.

The present invention is illustrated with reference to the accompanying drawings, throughout which reference numbers indicate corresponding parts in the various figures.

Referring to figure 1A, a slider switch assembly (200) for a flush switch (300) mounted on a module plate is shown. The flush switch (300) can be designed to perform either one way or two way. The flush switch (300) is designed to fit on standardized plate module sizes on back plates. In advent of the progressive increase in the architecture of homes, the flush switches (300) forms can become a variant that does not protrude out of the wall thereby increasing the asthetic appeal.

Referring to figures 1B, 2, 3 and 4, various views of the slider switch assembly (200) are illustrated. The slider switch assembly (200) of the present embodiment comprises a housing (100), a toggle (140), a slider (160) and a top cover (180). The housing (100) is designed to enclose a fixed contact (10) being capable of detachably coupling with a moving contact (30) which is configured at a bottom portion (Not Numbered). The housing (100) also comprises a spring loaded plunger (50) configured centrally therein. The housing (100) facilitates to engage with the toggle (140).

The toggle (140) forms a hinged engagement with the moving contact (30) at one end (Not Numbered). A central portion (Not Numbered) of the toggle (140) is adaptably configured to engage within the spring loaded plunger (50). This engagement allows the toggle (140) to expand and switch the positions of the spring loaded plunger (50). Another end (Not Numbered) of the toggle (140) adaptably engages with the slider (160).

The slider (160) includes a coupler (130) on a bottom portion (Not Numbered) which couples the another end of the toggle (140) therein. A middle portion (Not Numbered) of the slider (160) is flat structure which is adapted be slidably configured on a holder plate (150). The holder plate (150) is flat plate-like structure having a central aperture which allows the slider (160) to protrude therefrom. The slider (160) provides a top grip portion (Not Numbered) visible to a user for intended sliding operation on the top cover (180).

The top cover (180) has a central slit aperture (Not Numbered) for accommodating the top grip portion of the slider (160) therein. The top cover (180) engages with the housing (100) to form an outer cover for the slider switch assembly (200).

Further, when a user in order to perform an ON/OFF operation pushes the slider (160) from one operational state say from the OFF state, the sliding motion of the slider (160) enables the coupler (130) to move the toggle (140) along. The toggle (140) then expands the spring loaded plunger (50). This allows the spring loaded plunger (50) to attain a stable state in an alternate direction. Simultaneously, the toggle (140) thereby also crosses a toggle point / dead centre. Upon crossing of the dead centre, the toggle (140) enables the moving contact (30) to move down and thereby pressing against the fixed contact (10). With contact of the moving contact (30) against the fixed contact (10) the circuit is completed and the switch is thus turned in the ON operational state.

Advantages of the invention

1. The slider switch assembly (200) facilitates to achieve better aesthetics, improving functionality and increasing the ease of operation.
2. The slider switch assembly (200) facilitates a cost-effective and user-friendly assembly of the flush switch (300).
