Snap Action, Limit Switches

The 44505-2811 is a limit switch designed for interfacing electrical circuits in industrial automation applications. This limit switch is classified as a snap action style switch, which requires just a small amount of force to trigger the switch. The switch is available in a variety of sizes, colors and termination types and offers a variety of mounting options to fit in many industrial environments. As with any other limit switch, the 44505-2811 can be used for a variety of industrial automation tasks, including working with mechanical and pneumatics direction sensors, level monitoring, remote control power units and boiler safety controls.

Application Field

The 44505-2811 can be used in a wide range of industrial applications, from agricultural automation to material handling. The switch is designed to be used in areas where a reliable, precise switch is required. It can be used for a variety of applications, including motor and compressor control, throttle and clutch control, the operation of various machines, and in safety systems to ensure that an expected sequence of operations or events occurs.

Working Principle

The 44505-2811 limits switch uses a snap-action mechanism to trigger its switching contact when a preset amount of force is applied to its actuator. This force is known as the “actuation force” and must exceed a certain threshold, or the switch will not activate. This can be beneficial in applications where consistent triggering force is desirable.

When the preset actuation force is exceeded, the switch quickly moves from its unactuated (normal) position to its actuated position. There is a small gap between the normally open (NO) contact and the normally closed (NC) contact, when the switch is in its normal position. When the switch is actuated, the two contacts come together. This effectively creates an electrical circuit and closes it, which can be used to control the motor, the switch continues to stay in the actuated position until the actuation force is released and the switch returns to its normal position.

The 44505-2811 limits switch offers a variety of features, such as its dust-proof design, slow make and break contact circuit, snap-action switching and its ability to be used in hazardous areas. All of these features contribute to the robustness of the switch, making it a reliable choice for industrial applications.
