Snap action, limit switches are used to sense the position of moving parts of machines or the variation of electrical quantity. The D4C-4320 mini snap action switch has been designed with a slim body and a wide variety of mounting modes. It has also been designed to get easily into tight spaces within machines. It’s a reliable, compact limit switch with greater accuracy, precision, and reliability.

The D4C-4320 has two main application fields in industrial automation. The first of these are end limit positions (position detection). They are used to detect accurately the position of products in the context of an automated production line. This is used in order to control the starting, stopping, and transportation of products.

The second application field is limit switches based on current charging and/or discharging (state discrimination). They are used for electrical systems such as manual control boxes and lighting circuit control. This is used to detect the operating state of the circuit, for example on or off, thus providing the correct operation of various systems.

The working principle of the D4C-4320 is based on the sliding contact mechanism principle. It has an actuating arm and a movable contact which enables contact opening and closing. This arm is mounted on a ferrite permanent magnet core that acts as a field source. When the operative element, such as a lever or cam, moves, it activates the arm, hence switching the contact. The contact operation is transferred and strengthened by the magnet and the contact is held in the operation position until the arm is released.

The D4C-4320 has many design features that allow for greater accuracy, precision, and reliability. The laser welding of the contact helps to improve durability and endurance. In addition, its unique design allows for the fine adjustment of the contact gap and lever gap. This ensures reliable sensing and contact durability for long-lasting operation.

The D4C-4320 is also designed to be robust and reliable in harsh industrial environments. Its slim, lightweight design ensures that it can fit into tight spaces and be operated in a wide range of temperatures. The waterproof and dustproof design allows for outdoor and even underwater applications. The dustproof grade of the D4C-4320 is IP67 spec, while its waterproof grade is IP68 spec.

In summary, the D4C-4320 mini snap action switch is one of the most reliable, compact limit switches available. It is designed to be accurate, precise, and reliable in various industrial environments. Its design features, such as laser welding, IP67/IP68 dustproof/waterproof ratings, and adjustable lever gaps, ensure optimum performance, even in the harshest of environments.
