CR2940U301

The GE CR2940U301 General Electric Contact Block Pushbutton Switch is a versatile and reliable electrical component designed for various applications where momentary contact switching is necessary. This switch is compact in size, making it ideal for use in confined spaces or where space is a premium.

The CR2940U301 is a normally open (NO) type switch, meaning that it does not conduct electricity until the button is pressed. Once the button is actuated, the switch completes the electrical circuit, allowing current to flow. The switch is rated for a maximum operating voltage of 300 Volts AC or DC and a maximum current of 1 Ampere.

The switch housing is made of polycarbonate material, which provides excellent impact resistance and durability. The button is rated for up to 1 million cycles, ensuring long-lasting performance. The switch is also UL listed, which means it has been tested and certified by Underwriters Laboratories for safety and compliance with applicable industry standards.

The CR2940U301 features a flat, rectangular button with a diameter of 0.6 inches and a height of 0.3 inches. The button is also available in various colors, including red, green, yellow, and black, to suit different application requirements. The switch terminal block is located on the back of the housing and is designed to accommodate wires up to 12 AWG (American Wire Gauge) in size.

The switch terminals are spring-loaded and self-adjusting, making installation easy and secure. The switch also features a captive nut design, which helps to prevent the terminals from coming loose during operation. The switch is easy to install and can be mounted using screws or standoffs, depending on the application.

Overall, the GE CR2940U301 General Electric Contact Block Pushbutton Switch is a high-quality and versatile electrical component that offers reliable and long-lasting performance for various applications where momentary contact switching is required. Its compact size, durability, and easy installation make it a popular choice among electrical engineers, maintenance personnel, and DIY enthusiasts.
