Kontakt S is used to remove oxides and sulfides from electrical contacts and it protects against corrosion. This ensures a smooth flow of current through the connector, even in cases of already oxidized and worn contacts. It is especially useful in audio products, where the cleanliness of the contact is crucial.

This small LED is not just an ordinary LEDs – it’s specific because it has a built-in small integrated circuit (IC) that is able to turn on the LED light in 16 million different colors. IC is WS2812 and it uses a single wire can control thousands of these LEDs. With a little imagination by putting these pixels, you get superior effects with a minimum effort. These lamps are easy to control with Croduino.

A 7-segment display is a classic, frequently used and already familiar component. Size of the digit on the display is 0.56inch and the light it transmits is red. The display has a common anode.

The KIP switch is a durable SPDT toggle switch providing reliable on-off-on control for a wide range of electronics projects. It allows selection between two circuits or states from a single input, making it ideal for power management, signal routing, and mode selection. Its robust design ensures long-term mechanical and electrical performance in both prototypes and permanent PCB assemblies.
 
Rated for 250 VAC at 6 A, the switch handles low-voltage DC and moderate-power AC applications. The SPDT configuration offers three positions: one common terminal connects to either throw terminal, with a tactile click confirming state changes. Its compact form factor fits standard panels and enclosures.
 
Perfect for DIY audio, robotics, industrial control panels, or motor direction switching, the KIP switch provides dependable manual control. Pair it with Qwiic-compatible interface boards for seamless integration with microcontrollers. Add this versatile switch to your toolkit for durable, precise operation.
