1 FT SWITCH FRONT SAFETY BARRIER TECHNICAL FIELD
[0001] The field of disclosure relates generally to safety barriers, and more particularly, to safety barriers for switches for multi-circuit testing. BACKGROUND
[0002] Currently in the industry, switches for use in multi-circuit testing of switchboard relays, meters, and instruments expose switch operators to safety risks due to ease of contact with live elements within the switches. However, existing protective measures are limited in their applications and effectiveness to reduce these safety risks. For example, dividers are a commonly used protective measure. However, dividers may offer limited protection to operators, may expose operators to additional safety risks to install these dividers, and may not be compatible with additional components for use with these switches.
[0003] Based on the foregoing, a need exists for an easy to install, more reliable, and safer safety barrier for these switches.
[0004] This background section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present disclosure, which are described and / or claimed below. This discussion is believed to be helpful in providing the reader with supporting information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art. BRIEF DESCRIPTION

[0019] The following detailed description and examples set forth preferred materials, components, and procedures used in accordance with the present disclosure. This description and these examples, however, are provided by way of illustration only, and nothing therein shall be deemed to be a limitation upon the overall scope of the present disclosure. The following terms are used in the present disclosure as defined below.
[0020] Fig. 1A depicts a front view of a safety barrier 100 for a switch for multi-circuit testing, as described herein. Fig. 1B depicts a perspective view of the safety barrier 100 for a switch for multi-circuit testing of Fig. 1A. Fig. 1C depicts a side perspective view of the safety barrier for a switch for multi-circuit testing of Fig. 1A . The safety barrier 100 comprises a plurality of peripheral portions 110 disposed on opposing sides of the safety barrier 100. For example, the safety barrier 100 may comprise a first peripheral portion 110 disposed on a first side (e.g., a left side) of the safety barrier and a second peripheral portion 110 disposed on a second side (e.g., a right side) of the safety barrier 100, where the first and second sides are on opposing sides of the safety barrier 100. Each of the plurality of peripheral portions 110 may include a coupling aperture 115. The coupling aperture 115 may be used to couple the safety barrier 100 to a switch for multicircuit testing to allow the safety barrier 100 to be used with the switch for multi-circuit testing.
[0021] As shown in Figs. 1A and 1B, the safety barrier 100 includes a base 120 that extends between and connects the peripheral portions 110. The base 120 may be sized and configured to extend along a length of a switch for multi-circuit testing to align the safety barrier 100 with the switch for multi-circuit testing. The base 120 may connect the plurality of peripheral portions 110 to form a wide U-shape.
[0022] In an embodiment, the base 120 may include at least one clip slot 121a, 121b, 121c, 121d, 121e, 121f, 121g, 121h, 121i, 121j extending through a portion of the base 120. Each of the at least one clip slot 121a, 121b, 121c, 121d, 121e, 121f, 121g, 121h, 121i, 121j may correspond to one of at least one flap pair 124a, 124b, 124c, 124d, 124e, 124f, 124g, 124h, 124i, 124j formed on the base 120, described in more detail below. Each clip slot 121a, 121b, 121c, 121d, 121e, 121f, 121g, 121h, 121i, 121j may be adapted to align an alligator clip (not shown) for attachment to a crimped section of a test switch blade that is positioned within the corresponding flap pair CA 3300743 Date reçue / Received date 2026-02-03 5 124a, 124b, 124c, 124d, 124e, 124f, 124g, 124h, 124i, 124j. Additionally, the base 120 may include reinforced portions 122 along the length of the base 120 to provide support and rigidity to the base 120 and / or the safety barrier 100. The reinforced portions 122 may prevent the base 120 and / or safety barrier 100 from breaking during use by operators and increase durability of the safety barrier 100. The reinforced portions 122 may be disposed adjacent clip slots 121a, 121b, 121c, 121d, 121e, 121f, 121g, 121h, 121i, 121j. For example, the base 120 may include reinforced portions between clips slots (e.g., between clip slot 121b and clip slot 121c, between clip slot 121d and clip slot 121e, and the like) and / or above the clip slots 121a, 121b, 121c, 121d, 121e, 121f, 121g, 121h, 121i, 121j.
[0023] As discussed above, the base 120 comprises at least one flap pair 124a, 124b, 124c, 124d, 124e, 124f, 124g, 124h, 124i, 124j. Each flap pair comprises a corresponding first flap 125 paired with a corresponding second flap 130. For example, each flap pair may include a first flap 125 as a left flap in the flap pair 124 and a second flap 130 as a right flap in the flap pair 124. Each flap pair 124 may be sized to protect against insertion of objects, such as fingers, hands, large tools, and the like. This may prevent accidental touching of live components during use of switches for multi-circuit testing. As shown in Figs. 1 and 2, the safety barrier 100 may include a plurality of flap pairs 124a, 124b, 124c, 124d, 124e, 124f, 124g, 124h, 124i, 124j. Each of flap pair is adapted to partially house a test switch blade from a switch for multi-circuit testing to allow switch operators to safely access the test switch blade. For example, the safety barrier 100 may include ten flap pairs 124a, 124b, 124c, 124d, 124e, 124f, 124g, 124h, 124i, 124j but is not limited thereto. The safety barrier 100 may include any number of flap pairs as required for use with a switch for multi-circuit testing, such as including a flap pair for each test switch blade from the switch for multi-circuit testing.
[0024] The safety barrier 100 comprises at least one first flap 125 extending from the base 120. The at least one first flap 125 may include any number of first flaps to correspond to a number flap pairs needed. Each of the at least one first flap 125 may extend from a portion of the base 120 that is adjacent to a space 126 between the peripheral portions 110. The at least one first flap 125 may extend into the space 126 between the peripheral portions 110. For example, each of the at least one first flap 125 may extend from a portion of the base 120 closest to space 126 into the space 126 within the wide U-shaped formed by the peripheral portions 110 and the base 120. CA 3300743 Date reçue / Received date 2026-02-03 6 Accordingly, each of the at least one first flap 125 may be disposed within the space 126 between the peripheral portions 110.
[0025] In an embodiment, each first flap 125 of the at least one first flap 125 may include a plurality of first flap portions to define the structure of each first flap 125.

Each of the at least one second flap 130 may extend into a space 126 between the peripheral portions 110 from a portion of the base 120 adjacent to the space 126. For example, each of the at least one second flap 130 may extend into the space 126 within the wide U-shaped formed by the peripheral portions 110 and the base 120 from a portion of the base 120 closest to space 126. Accordingly, each of the at least one second flap 130 may be disposed within the space 126 between the peripheral portions 110.
[0029] In an embodiment, each second flap 130 of the at least one second flap 130 may include a plurality of second flap portions to define the structure of each second flap 130. The plurality of second flap portions may include a second flap first portion 130a. A first end of the second flap first portion 130a is connected to the portion of the base 120 adjacent to the space 126. The second flap first portion 130a is concave relative to the first flap 130 and / or first flap first portion 130a. The first flap first portion 125a and the second flap first portion 125b may define a bulbous-shaped spacing between the first flap first portion 125a and the second flap first portion 125b. The bulbous-shaped spacing between the second flap first portion 130a and the first flap first portion 125a may allow a user to maintain visibility of a make before break action for each test switch blade for a switch for multi-circuit testing. In an embodiment, the second flap first portion 130a may include a chamfered edge 131 along an edge of the second flap first portion 130a that is to be disposed distal from a switch for multi-circuit testing. The chamfered edge 131 may be similar to chamfered edge 127 and allow the first flap first portion 125a and second flap first portion 130a to guide a handle on a switch for multi-circuit testing together, as described in more detail in Figs. 3A and 3B.

The widened channel defined by the second flap third portion 130c and first flap third portion 125c may also be adapted to allow the flap pair to accommodate a handle that may be bent and / or positioned at an angle. Additionally, in an embodiment, the second flap third portion 130c may include slanted portion (not shown), similar to slanted portion 125d, at a portion of the second flap third portion 130c to be positioned closer to a switch for multi-circuit testing. The slanted portion may create sufficient clearance to allow for space for a current jack of a switch for multi-circuit testing when the safety barrier 100 is positioned on a switch for multi-circuit testing. Additionally, the slanted portion may be adapted to engage a current jack to prevent over movement of safety barrier 100 during closing of a test switch blade, as described in more detail below.
[0031] In addition, the plurality of second flap portions may include a second flap lower portion (not shown), similar to first flap lower portion 125e. The second flap lower portion defines an edge of the second flap 130 that is to be disposed proximal to a switch for multi-circuit testing. The second flap lower portion may be adapted to engage a portion of a switch for multi-circuit testing during closing of a test switch blade. For example, the second flap lower portion may be adapted to engage a hinge 16, shown in Fig. 3A, for a test switch blade, such as test switch blade 12, during closing of a test switch blade. In an embodiment, the second flaw lower portion may be a rounded shape to allow the safety barrier 100 and / or the second flap 130 to roll in a downward CA 3300743 Date reçue / Received date 2026-02-03 9 direction while the second flap lower portion 130 is engaged with a portion of a switch for multicircuit testing during closing of a test switch blade, as described below.
[0032] In addition, the safety barrier 100 may include a test probe guiding channel 140.

For example, the safety barrier 100 may include a first peripheral portion 110 (e.g., left peripheral portion) with a coupling aperture 115 with a left cover stud 13 of the switch body 11 extending therethrough and a second peripheral portion 110 (e.g., right peripheral portion) with a coupling aperture 115 with a right cover stud 13 of the switch body 11 extending therethrough. The coupling apertures 115 may enable the safety barrier 100 to be coupled to existing switches quickly and easily without the need for extensive disassembly of these switches. Further, the coupling apertures 115 and cover studs 13 may be used to properly position and align the safety barrier 100 for use with the switch for multi-circuit testing 10. Once positioned on the cover studs 13, the safety barrier 100 may be secured in position on the switch body 11 by a washer and nut tightened onto each cover stud 13.
[0038] Figs. 3A and 3B depict a detailed view of a flap pair of the switch for multi-circuit testing 10 of Fig. 3 during opening of a blade 12. During opening of a test switch blade 12 from the closed position, a widened channel defined by the second flap third portion 130c and first flap third portion 125c receives a bottom portion of a handle 14 to allow the handle 14 to engage with the second flap third portion 130c and first flap third portion 125c, as shown in Fig. 3A. Once the second flap third portion 130c and first flap third portion 125c are engaged with the handle 14, handle 14 may press against the second flap third portion 130c and first flap third portion 125c and cause the first flap 125 and the second flap 130 to flex outwardly. The outward flex of the first flap 125 and the second flap 130 causes the space between the first flap 125 and the second flap 130 to expand, as shown in Fig. 3B. The expanded space allows the handle 14 to pass between the first flap 125 and the second flap 130 and actuate the test switch blade 12 into the open position. In an embodiment, the safety barrier 100 may be made of a polycarbonate material and / or any other suitable plastic material to allow for the safety barrier to function as described herein.
[0039] Fig. 4 depicts a perspective view of the switch for multi-circuit testing of Fig. 2 with blades in an open position. Fig. 5 depicts a detailed view of the switch for multi-circuit testing of Fig. 2 with blades in an open position.
