Rotary Switches

Rotary switches are specialized devices used to electrically control the flow of current to electrical circuits. They typically consist of an insulated rotor and a stationary actuator. The rotary switch is the most fundamental type of switching mechanism, and is used to represent the basic functionality of an electrical circuit. The 77SP36-01-1-04N rotary switch is commonly used in many industrial, consumer, and defense applications requiring precise and reliable performance.

Application Field

The 77SP36-01-1-04N rotating switch is generally categorized as a double-pole rotary switch, and is available in various mounting styles and configurations. It is used in many types of industrial, consumer and defense applications to control the flow of current through electrical circuits. It is most commonly used in relay control systems, automated motor control systems, machine tool applications and industrial automation systems. Additionally, it can be found in consumer-level industrial control systems and applications, such as HVAC, power supplies, security systems, and hydraulic pressure systems.

Working Principle

The 77SP36-01-1-04N Rotary Switch uses a connect-disconnect contact system, which consists of a set of electrical contacts that rotate on a cam-type mechanism, providing a three-position switch. These contacts are activated and deactivated by the rotating motion of the rotary switch’s shaft, which is mechanically connected to the switch’s actuator. When the switch is in the closed position, the contacts make contact and current flows through the switched circuit. When the switch is in the open position, the contacts are interrupted, and the current stops flowing. When the switch is in the neutral position, the contacts are disconnected and the current flow is stopped.The 77SP36-01-1-04N rotary switch is made of a series of contact segments, which are designed to provide a precise, repeatable selection of contact points and switch positions. These contacts are available in both single-throw and double-throw configurations, and are designed to provide both positive and negative contacts. Additionally, the contacts are enclosed in a heavy-duty, insulated housing, and are rated for high-speed switching, high-current and high-voltage applications.The 77SP36-01-1-04N Rotary Switch is designed for use in a wide range of applications, including relay control systems, automated motor control systems, machine tool applications, industrial automation systems and consumer-level industrial control systems. It is rated for use in harsh environments, and can withstand temperatures, shocks and vibration. Additionally, it is easy to install and maintain, and offers a long service life.
