Crocodile Alligator Clip 50 mm Black and Red
Description: An alligator clip, also called a spring clip, creates a temporary electrical connection using a simple mechanical design.It gets its name because the jaws resemble an alligator or crocodile’s mouth, opening and closing to grip objects securely.The clip works like a spring-loaded clothespin that uses tapered, serrated jaws to hold wires or metal parts tightly.A spring pushes the jaws together, allowing the clip to grip objects and maintain a reliable electrical connection.Manufacturers design these clips for electronics testing, enabling quick connections without soldering or permanent joints.One jaw usually connects to a wire by crimping or soldering for efficient current transfer.Some clips use a bent jaw forming the inner contact of a 15 mm to 4 mm female banana jack.This design allows a fast, non-permanent connection between test circuits and laboratory instruments.A plastic cover or boot surrounds the clip to prevent short circuits and protect users from accidental shocks.Engineers and students use these clips widely in testing, prototyping, and educational experiments. Applications: Technicians use small clips (15 mm–40 mm) in electrical laboratories, schools, and college labs for quick test connections.Large clips, called automotive clips or battery clamps, use solid copper for low resistance and strong current flow.Users connect these large clips with thick insulated copper cables between automobile batteries or heavy electrical systems.Hobbyists and professionals rely on these clips for safe, reusable, and efficient electrical connections. Product Example: Check the Crocodile Alligator Clip 50 mm – Red and Black, made from durable stainless steel with a protective plastic shroud.Its spring-loaded jaws open wide to grip different wire sizes securely during testing or circuit connection.The serrated teeth ensure a strong, slip-free grip that maintains stable electrical contact during operation.

Out of stock3.7v – 4V Three Diamond shape COB led light [ Color – Cool White ]
[COB LED] Description This Chip on Board COB Led Light is a very small and innovative product, it comes in many different Shapes and Sizes. Its mostly used where the thickness of the product is a very important consideration. This led comes with an Aluminium metal back which acts as a heat-dissipating area for the Led, as these led got hot while running, but for the safety purpose we will recommend you to attach a metallic heat sink with it or paste it on the metal surface. Plate Dimensions ( L x B x H ):- ~74mm X ~22mm X ~2mm. Name of character/shape/letters on COB plate: SHAPE Diamond Dimensions of Led Area ( L x B x H ) :- ~60mm X ~14mm X ~1mm. Thickness:- 2mm. Input Voltage:- 3.7v – 4V. Max Input Voltage:- 4v (More than 4v Voltage will completely damage the product ) Aluminum back as a heat sink. Package Includes: 1 x 3.7v – 4V Diamond shape COB led light [ Color – Cool White ].
