Snap action limit switches are electronic components used to convert the physical actuation of a circuit board into an electrical signal. The 604HE222-6B snap action limit switch is an electronic component designed to detect the position or actuation of a moving element (i.e. reaching a predetermined limit) and respond to it by opening and closing a circuit as needed.

The 604HE222-6B is a single-pole, double-throw normally open contact-type switch. This means that its two contact points, located at opposite ends of the switch, are in an open-circuit state in the default position. When the switch is actuated, the contact points close the circuit and complete the flow of electricity.

The 604HE222-6B limit switch is an example of a mechanical, snap action switch. This type of switch is designed with a physical actuation element that uses tension to keep the contact points in an open or closed state, until some sort of force is applied. The physical force applied to the actuation element causes a “snap”, and the switch instantaneously transitions either the default open or default closed position. In the case of the 604HE222-6B, this is normally open (NO) switching.

The 604HE222-6B is highly resistant to dust, particles, and moisture, making it suitable for use in harsh environments. Its contact rating is 250VAC at 1.5A, and it has a temperature rating of -20°C to 85°C. Its mechanical life is over 1 billion operations, and its electrical life is over 5 million operations.

In terms of applications, limit switches such as the 604HE222-6B can be used in automation and control systems that require precise motion sensing and precise counting. The switch can be used to sense the position of objects such as door and window openers, machine components in conveyor systems, and more. It can also be used in a variety of safety applications including fire safety and safety shutdown systems.

The 604HE222-6B is a reliable and cost-effective limit switch that is well-suited for a variety of applications. Its snap action design and superior durability make it an ideal choice for detecting the actuation and position of moving elements in industrial and commercial settings.
