Rotary switches are versatile components that are used in almost all types of electronic and electrical circuits. They are designed to switch an electric circuit on or off depending on the orientation of their rotary arm. They are also known as panel switches or stepping switches. The 711-7-T3 rotary switch is particularly suitable for power switching applications.

Design and Features of the 711-7-T3 Rotary Switch

The 711-7-T3 rotary switch is a three-pole, four-position, off-on-on-on, spring-return wafer type switch. It is also provided with four terminals having a large contact spacing of 0.25 inches (6.35mm). Therefore, it provides good contact reliability and arcing protection. Additionally, the switch has two wiping contact arms and four independent contact fingers made of steel. Its body is a molded glass-filled polyester, giving it a black finish with a glossy appearance. It is provided with a polyamide actuator, which is available in a non-illuminated, flat-pushbutton version.

Application Fields of the 711-7-T3 Rotary Switch

The 711-7-T3 rotary switch is particularly suitable for switching applications requiring high current load handling capacity and maximum contact reliability. It is used in telecommunications and other industrial instrumentation circuits, high-current devices such as power inverters, power supplies and transformers, various types of motors, and in other numerous applications demanding high performance.

Working Principle of the 711-7-T3 Rotary Switch

The 711-7-T3 rotary switch works on the principle of a rotating armature being actuated by a spring-return mechanism. When the switch is off, the armature is in the fully withdrawn position and is disconnected from the circuit. When the armature is rotated in a clockwise direction, the electrical contacts are made, allowing current to flow through the circuit. When the armature is rotated in the opposite direction, the electrical contacts are opened and the circuit is disconnected.

The switch\'s durable construction, its high-current load handling capacity, and its spring-return mechanism make the 711-7-T3 rotary switch an ideal choice for power switching applications. With its features, it can be used in a variety of industrial and commercial applications, making it a versatile and reliable component for any circuit design.
