Rotary Switches

Rotary switches are widely used for manual operation and switching. In its most common form, it consists of a spindle or wheel which is rotated from one position to another to selectively open or close electrical contacts in each recognized position. It is also widely used in industrial control applications as an economical way to provide many switching functions from a single switch.

MD00L1NCGD Application Field and Working Principle

The MD00L1NCGD is a heavy-duty rotary switch which is suitable for commercial and industrial applications. It is an economy version of the famous series M rotary switch and can withstand a full load current up to 6A and a voltage up to 250VAC. It has a total of six positions along the wheel which offer 6 amp of load capacity. It is designed with a positive snap action while switching, no mechanical or electrical lopping and UL 94V-2 flammability rating.

The internal construction of the MD00L1NCGD primarily consists of a black plastic casing, an internal brass contact and a spindle for external attachment. The spindle is spring-loaded, allowing for an over-centre action when turning and thus reduces the risk of accidentally opening the switch. Inside the switch, a series of springs and levers are connected together, with the contact being located at the end of the switch\'s spindle. As the spindle turns, it causes the springs and levers to be pushed, thus opening or closing the contact. Once the desired position has been found, the spindle can be locked in place.

The contact mechanism of the MD00L1NCGD rotary switch is designed to ensure that there is a contact break at every position. This is done by placing two arcs of contacts on either side of the switch so that when the contact is closed, there is a small gap between each contact arc. This ensures that an electrical current is always broken when the switch is in transition from one position to another, thus preventing current from continuously flowing through the switch when it is in transition.

The MD00L1NCGD is primarily used for controlling electrical circuits and is suitable for a variety of commercial and industrial applications. It is commonly used in applications such as motor control, fan speed control, and other similar applications. It is a popular choice for printed circuit board applications, especially in combination with a fuse and terminal block, where it can be easily fitted due to its small size. It can also be used in combination with switches and other components in control or logic systems. Its economical design and reliable construction make it one of the most popular rotary switches available.
