A momentary push switch is commonly used in control circuits such as contactors, relays, electromagnetic starters, and other electronic systems. It operates only while being pressed—turning ON when pressed and automatically turning OFF when released. This type of switch is also widely used in automotive and household applications. Applications: Educational...

The RED R13-507 16mm No Lock Push Button Momentary Switch is a compact and dependable switch for managing electrical circuits. Designed to fit a 16mm mounting hole, it can handle up to 3A at 250V. The switch operates by turning ON when pressed and automatically returning to OFF when released,...

The Red Side LED 0805 is a compact surface-mount light-emitting diode (SMD LED) designed to emit bright red light from the side of the package. Unlike traditional top-emitting LEDs, this side-view LED directs light horizontally, making it ideal for edge-lighting, backlighting, and indicator applications where space is limited. Manufactured in...

The KY-025 Reed Switch Module is a magnetic field detection module designed to sense the presence or absence of a magnet using a normally open reed switch. The module integrates a sealed glass reed switch with an LM393 comparator, providing both analog (AO) and digital (DO) outputs for flexible interfacing...

The KY-021 Reed Switch Module is a compact magnetic field detection module designed to detect the presence or absence of a nearby magnet. It uses a normally open (NO) reed switch enclosed in a hermetically sealed glass tube that closes when exposed to a magnetic field, producing a digital output...

The Reed Switch Module with LM393 Comparator is a magnetic field detection module designed to detect the presence or absence of a nearby magnet. It combines a high-quality normally open (NO) reed switch with an LM393 voltage comparator, providing a clean and stable digital output for microcontroller-based applications. When a...

The 0 Ohm 1% 1/4W SMD 1206 resistor is a special type of passive component that functions primarily as a PCB jumper link rather than a traditional resistor. Although it is labeled as “0 Ohms,” it provides a very low resistance path, allowing electrical signals to pass through with minimal...

The 100Ω 1% 1/4W SMD 1206 resistor (100E) is a commonly used surface-mount passive component designed for precise current control and voltage management in electronic circuits.
