Snap Action, Limit Switches – D4C-1701 Application Field and Working PrincipleLimit switches are widely used in industrial and building automation equipment, and they are one of the most commonly used devices in the fields of electronics and automation. The D4C-1701 series Limit Switches are designed to fulfill the accuracy requirements for factory automation applications.The D4C-1701 series Limit Switches offer high speed and repeat-ability. The housing materials are mechanically robust and the actuators have long life. In addition, these switches are sealed and have built-in surge protection, providing reliable operation and high performance in extreme manufacturing environments.Application FieldThe D4C-1701 is a highly reliable Limit Switch and is suitable for a wide variety of industrial applications. It can be used in processes such as feed/eject operations, on/off mode control, pressurized systems, programmable logic controller (PLC) signaling, and part sensing for automation systems.This Limit Switch can be used in the following industrial fields:

• Material handling applications
• Food and beverage applications
• Machine tools
• Textile production
• Packaging machinery
• Robots
• Medical instruments
• Automotive assembly

Working PrincipleThe D4C-1701 Limit Switches feature a snap action mechanism. It combines a cam and lever with a switch contact, which is activated when the cam moves the lever. The snap action mechanism ensures that the switch contact is activated when the lever reaches the end of the cam. When the lever is at the reset position, the contact opens up, and the switch returns to its initial state.The D4C-1701 Limit Switches are connected to electrical control systems and react to the changes in position when the actuator is pressed. The switch can be set to open or close the circuit. When the actuator is in the "close" position, current is allowed to flow through the switch and circuit. When the actuator is pressed, the current is cut off.ConclusionThe D4C-1701 series Limit Switches offers high speed and repeatability. It also provides a highly reliable switch for a wide variety of industrial applications, including material handling, food and beverage, machine tools, and robots. The switch has a snap action mechanism, which ensures that the switch contact is activated when the lever reaches the end of the cam. The switch can be set to open or close the circuit depending on the position of the actuator.
