Rotary switches are essential items in the business of modern electrical and electronic equipment. The A12405MNZB range of switches is particularly suited to applications in power and signal switching and distribution. The range includes several models with a range of contact options and ratings, covering a variety of applications.

The A12405MNZB is a unitary switch in the form of a continuous rotary knob or handle. It is a variable resistor type switch where the position of the control or knob, determines the resistance and consequently the operation of the connected circuit. It is designed for use as a power switch or as a signal-switching device for controlling lighting effects or special effects in broadcast and sound recording.

The switch is made up of several components including a base, a rotary actuator, a contact assembly and a terminal unit. The base is made of an impact-resistant plastic material and includes an opening to receive the electrical contacts. The rotary actuator is a wheel-shaped lever which is attached to the base and turns freely when an external force is applied. This causes the contacts in the contact assembly to move and bridge or break electrical connections. The terminal unit is made of metal and is responsible for transmitting the electrical energy into the appropriate circuit.

The A12405MNZB range of switches are available with various contact ratings, from 0.1A to 10A. They can also be used in applications with AC or DC power. The travel of the rotary actuator is adjustable and can be set to up to 30 degrees. This makes it possible to select which contacts the switch makes and breaks, for finely-tuned control of a circuit.

The A12405MNZB switch is suitable for use wherever reliable switch control is essential. Each model offers a very high level of reliability and long-term service life. They are suitable for use in many industrial fields, such as: commercial lighting, machine control systems, electronics, telecommunications and instrumentation.

When used in power applications the A12405MNZB switch offers excellent performance. The switch can be used to cut off and restore power rapidly, due to its high contact rating and low contact resistance. This makes the switch ideal for use in applications where high current levels are needed and fast response times are expected.

When used in signal switching applications, the switch is capable of very accurate and fast switching between circuit states. This makes it suitable for controlling lighting effects or for making automatic system tests in broadcast and sound recording. The switch also features a contact bounce time of less than 1 ms and a maximum contact resistance of less than 0.2 ohms.

The A12405MNZB range of switches are designed with the modern industrial environment in mind, offering excellent quality and reliability in all applications. With a range of contact options and ratings, the switches are sure to fulfil the most demanding of requirements.
