Snap Action, Limit Switches

The D4A-3305N is a type of automatic, snap-action limit switch. It is typically used for electromechanical control systems, mostly involving adjustable sensors. Specifically, the switch triggers when a certain level of the mechanical force is exceeded and will switch off when this applied mechanical force is released.

These types of switches are usually found in industrial, commercial and home automated systems, and is most commonly used in automated HVAC systems. This type of switch also has the capability to be used with machine tooling and/or as a safety switch.

The D4A-3305N is designed to switch ON and OFF when an operator manually opens or closes an operator-actuated assembly. This switch is intended to be used as a substitute to conventional mechanical limit switches and is a direct replacement for most normally open switches.

Working Principle

The working principle of the D4A-3305N limit switch is fairly simple. It consists of a switch body, actuator arm and roller element. When the actuator arm is rotated in either a clockwise or counter-clockwise direction, the roller element contacts the switch body and closes an electrical circuit. This closing of the circuit energizes the contacts, which will then toggle the application that it is connected to.

The D4A-3305N is designed with a wide temperature range for operation in varying environmental conditions, and is rated for operation at temperatures ranging from -32°F (-35°C) to 176°F (80°C). It is also designed with a long-life snap-action mechanism to provide quick and reliable switching action while also offering a maximum of 500,000 mechanical life cycles.

Application Fields

The D4A-3305N is typically used in industrial and commercial applications where a high quality and reliable form of limit switch integration is desired. It is typically used in the following fields:

• Automated HVAC systems
• CNC machine tools
• Pressure/position sensing
• Security systems
• Motorized stage and uplight systems
• Industrial robots and machine automation

This type of switch has also been used in home automation applications, namely in garage door openers, door chimes and door locks. It is also used in fire suppression systems and safety applications for operating heavy equipment.

Advantages

One of the main advantages of the D4A-3305N limit switch is that it is very compact in size, which makes it well suited for use in tight spaces. It is also designed with an extended life-cycle rating, which ensures that it is a reliable and long lasting addition to any system. The high temperature rating of this switch ensures that it can withstand extreme temperatures with no issues, which makes it an optimal solution for temperature-sensitive applications.

In addition, this type of switch is designed with a UL certification, which provides users with further peace of mind that the product is held to the highest safety and manufacturing standards. The D4A-3305N also has the capability to be used with a variety of voltage sources, making it ideal for a range of applications.
