Rotary switches are used to regulate an electrical circuit by controlling the current flow. The 51SPT30-01-4-02S is a particular type of rotary switch that is commonly used in appliances and industrial automation. In this article, we will explain the application field and working principle of the 51SPT30-01-4-02S rotary switch.

Application Field

The 51SPT30-01-4-02S is designed for use in appliances and industrial automation. It is a high-voltage switch that is capable of handling currents up to 30 amperes. It has a compact design and is suitable for use in narrow spaces. It is rated for continuous use and is resistant to shock and vibration. The switch also has a high degree of contact stability, which means that it has a low tendency of contact bouncing, which is sometimes associated with rotary switches. Additionally, the switch is double-pole with four positions, making it suitable for various wiring circuits.

Working Principle

The 51SPT30-01-4-02S is a double-pole rotary switch. This means that when the switch is turned, two separate electrical contacts are opened or closed. The switch has four positions, which are mechanically interlocked. This means that when the switch is in one position, the others are prevented from being selected. This ensures that only one contact is opened or closed at any one time.

The 51SPT30-01-4-02S is actuated with a lever. When the lever is moved to one of the four positions, the contact arm will slide along a track to open or close the electrical contacts. At each position, the contact arm is locked in place with a spring-loaded detent. This allows the electrical contacts to remain open or closed in a stable position, ensuring a reliable connection even under conditions of vibration or shock.

The 51SPT30-01-4-02S is an economical and reliable solution for controlling an electrical circuit. The switch’s compact design makes it suitable for use in a variety of applications and its high degree of contact stability ensures reliable operation. With its double-pole design and four positions, the switch is a versatile solution for controlling a variety of electrical circuits.
