Connect wires to circuit boards with Molex Mini-Fit push-in connectors. These connectors are easier to detach than Amphenol PV connectors, so they’re often used for prototyping. A complete connector consists of a sleeve housing, sleeves, and a circuit board plug (all sold separately). To assemble these connectors, crimp sleeves onto your wires, then place them inside a sleeve housing. Once you’ve wired the sleeve housing, slide it onto a circuit board plug.

Connect wires to your circuit board with these Molex KK push-in connectors. A good choice for prototyping, they require less force to disassemble than Amphenol PV connectors. However, this means that they are less secure in more demanding applications.

For a complete connection, choose a plug and housing with the number of poles that matches the number of wires you need to connect. You’ll also need one sleeve for each wire.

Often used as status indicators, in displays, or to check circuit function in prototyping and testing, these bulbs have wire terminals to directly install onto circuit boards. As LEDs, they last longer, are more efficient, and produce less heat than other types of bulbs. Vibration won’t cause these bulbs to malfunction. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. They require a resistor (sold separately) to limit current.

Wire terminals allow you to connect these bulbs to a power source through a panel. These bulbs are sized to fit into tight spaces such as signs, instruments, indicators, and flashlights. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.
