Rotary Switches

Rotary switches are an essential component of many electrical systems. They are used to connect or disconnect electrical circuits and they are also used to control settings, like switching between different states. Commonly used in industrial and home automation applications, rotary switches have been around since the early 19th century.

The 423521-1-03S is a special type of rotary switch. It is a single pole, three-position switch that is typically used for controlling settings or for isolating two different circuits. This switch comes with 4 flat terminals, one for each position of the switch. It is rated for 250V and 11A and it has a wide range of application scenarios.

Application Field

The 423521-1-03S rotary switch is mainly used in industrial and home automation applications. It can be used for controlling lights, fans, motors, and other household appliances. It can also be used for switching between two circuits to isolate them, allowing for greater control and safety.

In an industrial setting, this switch can be used to create customised control solutions such as fan motors, autostops, and other automated settings. In addition, it can be used to create customised security settings and to electrically isolate two circuits.

Working Principle

The 423521-1-03S rotary switch is a single-pole, three-position switch. It uses four flat terminals that are connected to a three-position insulator housing and an adjustable cam. The adjustable cam is turned when the switch is engaged and this causes it to trip across the terminal, creating a connection between two of the terminals and an open position for the third to create an isolation between the two.

The 423521-1-03S offers excellent reliability and long lasting performance, even with frequent use and in harsh environments. It is designed for easy installation and it is fitted with reliable terminals that ensure a good electrical contact.

The 423521-1-03S rotary switch is an essential component in many industrial and home automation applications. It is reliable and easy to install and it can be used to control lights, fans, motors, and other appliances quickly and safely.
