More specifically the embodiments described herein relate to a Switch Assembly with push and hold mechanism in multiple zones in a Printed Circuit Board Assembly (PCBA) with pre-clipping and post-clipping functions. Particularly relates to ease facilitation in switch function with self-aligning features to accommodate the PCBs of different thickness and slot dimensional variations in a desired position.

Background of the Invention

[002] In electrical switches, Printed Circuit Board (PCB) plays a dominant role in determining the efficient functionality of a switch assembly and used to electrically connect electronic components. Usually, these printed circuit boards include power modules which house various electrical devices. In the switching assembly, screw fitting is used largely for fixing the printed circuit board to the frame on the surface mounting boxes.

[003] In prior arts, the switching assembly (casing) can be assembled with the Printed Circuit Board Assembly (PCBA) by snap together, screw system, normal snapping system, ultrasonic- press, screw fastener and adhesives. The PCBs are inserted within the housing of the switching assembly and can be removed for various reasons like maintenance, repairing works etc... In the current scenario, there is no easy configuration system available for stress-free installation and uninstallation of the PCB assembly from the housing of the switching assembly. Further, no user friendly compatibility of the PCBA with various switching architecture (such as modular and German architecture) are offered in the current period as thickness and slot dimension variations of the PCBA are big constrains.

[004] On the whole, the current switching assembly influences various complications such as increase in number of part count, complexity in electronics design, increase in product cost and improper switching functionality due to PCBA thickness tolerances, PCBA layout cut out dimension variation, PCB holding casing part variation and tool variation and further, no PCBA self- aligning features available in the switching assembly in the current trend. [005] Therefore, there is a need in the prior art to develop a universal switch assembly to be compatible with various switching architectures to overcome the problem associated with the prior arts. Further, there is a need for ease facilitation in switch function with self-aligning features to accommodate the PCBA assembly of different thickness and slot dimensional variations in a desired position.

According to an embodiment, the casing 104 composed of a plurality of flexible catch elements 501 at the opening edge in an opposing side region of the casing 104, where each flexible catch elements 501 is formed with an angular primary slider 502, a flexible locking member 513, a secondary slope 504 and a tertiary slope 503. While the casing 104 is assembled to the intermediate cover 103, the PCBA 108 slides on the tertiary slope 503 towards the secondary slope 504 of the catch elements 501 with respect to angular contact movement of the PCBA 108, such that the PCBA 108 is pre-clipped and secured between the casing 104 and the intermediate cover 103; and wherein during installation, the insert assembly 201 is fixed on the fixing frame by sliding the fixing frame on the primary slider 502 such that the flexible locking member 513 is pushed against the PCBA 108, which slides and aligns the PCBA 108 on the secondary slope of the catch elements 501 to firmly hold the PCBA 108 within the insert assembly 201.

[0069] Figure 6a illustrates a perspective view of the pre-clipping action and post-clipping action of the universal switch assembly along with rigid support function 600 A, according to an embodiment. In an embodiment, the flexible locking member 513 can push back and hold the PCBA 108 and provides rigid support during pre-clipping 508 and post-clipping 515 actions. In an embodiment, during actuation, if push button 601 is pushed the PCBA cannot move due to rigid support function of the flexible locking member 513.

[0070] Figure 6b illustrates a perspective view of the snap push back feature of the universal switching assembly to hold the PCBA of variable thickness 600 B, according to an embodiment. At 602, snap push back feature is present to hold variable thickness of PCBA 108 and further, the rigid horizontal torsional legs 505 can hold the twisting and bending actions and facilitate to accommodate variable thickness PCBAs 108.

[0071] Figure 6c illustrates a perspective view of the structural membrane for pushing the snaps 600 C, according to an embodiment and Figure 6d illustrates a perspective view of the universal switching assembly with self-aligning arrangement for tolerance variations during installation 600 D, according to an embodiment. According to an embodiment, the insert assembly 201 consists of strong structural element 603 for pushing the snap in. At 600 D, a perspective view of the universal switch assembly with self-aligning arrangement for tolerance variations to accommodate the PCBA of different dimensional variation is illustrated.

[0072] Figure 7 illustrates a perspective view of the universal switching assembly for proximity sensors 700, according to an embodiment. According to an example embodiment, the universal switch assembly consists of detecting element / lens 401, a rocker 105 and tact switch 107 for proximity sensors.

[0073] Figure 8 illustrates a perspective view of the universal switching assembly for rotary dimmers 800, according to an embodiment. According to an example embodiment, the universal switch assembly consists of a knob 701, a shaft 702 and a potentiometer 703 for rotary dimmers. [0074] Figure 9 illustrate a flowchart for method of the switching assembly with push and hold mechanism in multiple zones in PCBA, according to an embodiment. In an embodiment, a method of the switching assembly with push and hold mechanism in multiple zones in PCBA, wherein the method comprising the step of: At block 901, Pushing the PCBA by a plurality of flexible catch element in a casing aligns and holds the PCBA in the assembly line. At block 902, assembling the casing to an intermediate cover and the PCBA slides on the tertiary slope towards the secondary slope of the catch elements for pre-clipping and securing the PCBA between the casing and the intermediate cover. At block 903, snapping the insert assembly to the fixing frame by sliding the fixing frame on the primary slider and the flexible locking member is pushed against the PCBA and At block 904, sliding and aligning the PCBA on the secondary slope of the catch elements to firmly hold the PCBA within the insert assembly for post-clipping during installation.
