1HE49 Application Field and Working PrincipleThe 1HE49 switch, commonly referred to as the Euroswitch, is a type of snap action, limit switch. Originally developed in Europe, the 1HE49 is a small and highly reliable electrical switch designed for industrial control applications.The 1HE49 was originally designed for applications where a small switch is required and where mechanical strength and abuse are crucial factors. The 1HE49 is typically used for emergency stop buttons, actuator switches, air-pressure switches, and for various mechanical control components. Due to their durability and reliability, 1HE49 switches are also used in automotive, aerospace, general manufacturing, and medical industries.The 1HE49 is a snap action switch, which means the switch operates with a quick snap action. This snap action occurs when the switch contacts are forced to move from a closed position to an open position, or vice versa. When the switch is forced to move, the switch contacts separate and an electrical circuit is broken. When the switch is released, the switch contacts snap closed and the electrical circuit is completed. This snap action can be repeated as many times as necessary, making the 1HE49 ideal for applications where the switch must be repeatedly operated and the operation must be fast.The 1HE49 switch utilizes dual-action contacts for reliable switching. These dual-action contacts are designed to limit the amount of contact rebound when the switch is released. This contact rebound can result in false contacts and interruption of electrical signals, so the dual-action contacts are a key feature of the 1HE49.In addition to the dual-action contacts, the 1HE49 also has an integral coil spring. This coil spring helps ensure consistent operation of the switch, even under harsh environmental conditions. In addition, the coil spring helps maintain the switch settings even when the switch is cycled.The 1HE49 also features a variety of features to ensure long-term reliability. For example, the switch is sealed with a double-tapping cover to protect against dirt and dust. This cover also helps protect the switch from shocks and vibration. In addition, the 1HE49 has a rugged alloy housing that is resistant to shocks, vibration, and other environmental factors.The 1HE49 is available in various sizes, styles, and configurations to suit the needs of different applications. For example, some models feature a two-position toggle for additional control. Other models feature a push button for easier operation. Still other models include a test switch for diagnostics or calibration.Overall, the 1HE49 is a highly reliable and durable switch designed for industrial applications. It features self-contained snap action, dual-action contacts, and a rugged alloy housing for superior performance and long-term reliability. The switch is available in a variety of sizes, styles, and configurations to suit the needs of different applications.
