D4C-3403

Snap-Action, Limit Switches are commonly used when small, responsive, short-running mechanical components are desired in your device or process. These switches, including the D4C-3403, provide a high-efficiency and reliable interface between electrical equipment and system-level control of the device. The D4C-3403 is designed for use in a general purpose environment for a wide variety of industrial, transportation, and recreational applications. Typical applications include control of heating and cooling systems, ventilation of industrial areas, opening and closing cargo doors, temperature control of liquids, or use as a safe switch in hazardous environments. The D4C-3403 features a spring-biased, roller-lever actuator mechanism that is used to open and close contacts. This switch is available in two configurations: Normally Open (NO) and Normally Closed (NC). The actuator travel is adjustable to set the pre-contact trip points, thus facilitating desired switching on/off points. When the actuator lever is pressed, the force of the spring is displaced and the contacts open or close, depending on the configuration. The opening of the switch generates an electrical signal. When the actuating force is removed, either manually or by the application of an external force, the spring will automatically close the contacts, thus returning the switch to its original or normal position. The most common connection types for the D4C-3403 are a male threaded shaft and a female socket. Other connection types are also available. The D4C-3403 also features a tension adjustable screw for easier adjustment of the actuation point, and a mountable design for additional flexibility. The package and connection type is highly customizable, so it can be adapted to fit into various different structures. The D4C-3403 is designed for long-term use in light industrial and recreational applications with an operating temperature range of 10°C to 55°C (50°F to 130°F). The unit is UL and cUL approved, CE certified, NEMA compliant, and RoHS and REACH compliant. To further ensure its reliability, the contacts are made of corrosion-resistant silver and have a low contact resistance rating. The outer shell is resistant to corrosion and rust, and made of a durable material to prevent wear and tear.Overall, the D4C-3403 is an effective, responsive and reliable Snap-Action, Limit Switch that is suitable for a variety of applications. Its multiple configurations, customizable options, and robust design make it an ideal choice for standard and special mechanical systems alike.
