Rotary Switches

Rotary switches are electro-mechanical devices which provide a range of switching action to control the flow of electrical current in a circuit. The switch has two or more poles and when it is rotated or turned, it may open and close different combinations of poles or contacts to form an electrical path between the source and the load.

A rotary switch is typically used for the selection of multiple electric devices, for instance, an appliance such as a heater, light, or fan, or for the use of multiple electrical sources such as for powering a motor. In addition, it can be used to select two or more circuits, or to serve as a selector switch for a variety of functions. In most rotary switches, a movable contact arm is moved by turning a knob, lever or dial.

093121-1-06N Application Field and Working Principle

093121-1-06N is a field-configurable rotary switch that performs very similar to the dial of a telephone. It is generally used in medium voltage applications and is suitable for switchgear control and protection. The 093121-1-06N features two distinct center positions: OFF and ON. Depending on the number of switch poles, there may be up to 12 selectable positions in one full revolution.

The working principle of the 093121-1-06N rotary switch is simple and reliable. When the operator turns the handle, a linear displacement mechanism is activated, which moves the center ON/OFF contact in arc shape. When the center contact moves, it pushes the contacts in the different poles against the mechanical springs. This actuates the contacts to move and make contact with the desired preset contact points in the circuit.

The 093121-1-06N rotary switch is designed to ensure a positive break and make operation. Its operating mechanism uses an index plate with multiple contact points. When the rotary switch is switched from one position to another, a combination of index plate, plungers and contact points activate to make and break contact of the preset positions in the circuit.

The mechanism built into the 093121-1-06N ensures that there always is a positive indication of the switch position in the circuit. It also ensures that the current flow is switched from one point and to another without any down time. Moreover, it has an integral arc contactor, which ensures that the contact points are separated on the transition from one pole position to another.

All these features make the 093121-1-06N an ideal choice for a wide range of applications. It is suitable for use in automation systems, communication and power supply systems, and industrial control systems. In addition, it is suitable for applications that have high switching frequency and short-circuit protection requirements.
