Pushbutton switches enable users to control a circuit by pressing a button. The SB221NO is a single-pole, single-throw switch, which means that, when the button is pressed, it connects the two sides of the switch and therefore closes the circuit. It is a momentary contact switch, meaning that the circuit is closed only while the button is held down and opens when the button is released. The SB221NO is designed for use with 1/4" quick-connect terminals and can be used in applications where the operating temperature is between 0 and 60°C. It is UL recognized, CSA certified, and ROHS compliant, making it suitable for applications requiring a high degree of reliability and safety.

The SB221NO is made from a durable, impact-resistant plastic that is highly resistant to moisture, dust, and corrosion. The contact surfaces are gold-plated for maximum durability and efficient electrical performance over time. The contacts are rated for 1/3 horsepower (250V AC/125V DC) and resistances up to 10 milliamp. They are rated for 10,000 make and break cycles, meaning that the switch can handle frequent on/off cycles. The operating temperature range is from -45°C to +85°C, making the switch suitable for a wide range of applications.

The SB221NO can be used in a variety of applications, including automobiles, marine and industrial applications. It is suitable for use as an electrical starter switch, a power control switch, or a switch to control other circuits. It can also be used in applications requiring a watertight seal, such as in water fountain control circuits. It is a great choice when you need a reliable and durable switch that provides reliable operation in a variety of environments.

The SB221NO is a great choice for electrical engineers, as it is a cost-effective switch that is highly reliable and easy to install. It provides reliable operation in a wide range of applications and its durable construction makes it suitable for use in a variety of environments. Its compact size, relatively small operating current, and large number of make and break cycles make it suitable for high-power applications as well. The SB221NO is an excellent choice for reliably controlling circuits and power sources.
