DA3C-F1RB

Snap Action, Limit Switches

DA3C-F1RB is a type of snap action, limit switch designed to open and close a circuit under a certain condition. It works by sensing the presence of an object and turning off or on an electrical connection.Simply put, the switch is activated when a movable portion of the switch is pressed in or out to cause the contacts to close or open the associated electrical connection. These switches are used in a variety of applications including door openers, vending machines, doorbells, security alarms, thermostat controls, industrial equipment and more.

The working principle of such a switch lies in the mechanical action of a bi-stable toggle. This means that the switch opens or closes depending on its current position. The toggle is mounted within the switch body and is spring-loaded with a tensioning device. This device provides a certain amount of force on the toggle, locking it into the “on” or “off” position. When the toggle is forced into the opposite position, the tensioning device provides a counter-force to return the toggle back to the original position. This ensures that both positions are stable and that the switch can withstand the test of time in both open and closed positions.

The switch also contains a pair of contacts within the toggle. These contacts electrically connect the two circles of the toggle, and when the toggle is pressed down then the contacts will disconnect, breaking the circuit. The switch will then remain in the open position until the toggle is released and returns to the “on” position. The tensioning device will also ensure that the contacts remain closed, maintaining the integrity of the circuit.

When choosing a limit switch, it is important to consider several factors such as the environment it will be placed in, the type of mechanical connection, the electrical rating, and the types of switches available. These factors should be considered together to ensure that the switch is suited for the specific application.

DA3C-F1RB snap action limit switches are designed for use in a variety of industrial and consumer applications. They are reliable and feature a robust design for long-term performance. The switch has current ratings suitable for most applications and is available in multiple actuator styles.

Overall, this type of limit switch is suitable for a wide range of applications and is an ideal choice for many industrial and consumer applications. It is a reliable, versatile switch that can handle a variety of conditions and is available in different configurations to suit specific needs.
