Rotary Switches

Rotary switches are switches in which the rotation of a knob is used to open and close the contacts. A rotary switch may be used either to control the interconnection of contacts in a circuit or to control a single contact that makes and breaks the connection between two separate circuits. An example is a C7D0212N-30C, a significant non-shorting rotary switch typically used in telecom applications.

C7D0212N-30C Application Field and Working Principle

The C7D0212N-30C is a 12-position non-shorting rotary switch designed specifically for telecom applications. It is designed to be used in a variety of applications such as signal switching, signal routing, signal selection, and signal combination. Its applications include distribution systems, pay phones, alarm panels, pre-selection systems, voicemail systems, inter-connecting systems, and line access systems. The switch is also well-suited for low power switching, low loss switching, interfacing, signal routing, signal-level conversion, and wireless communications.

The C7D0212N-30C is constructed from two different materials. The exterior is a combination of phenolic and ABS, while the interior contains brass components. The contacts themselves are made from nickel silver material. The switch is designed with a circular dial with twelve different positions. Each of these positions corresponds to a different contact. The positions are labeled on the outside of the switch in order to make it easier to find the correct contact.

The C7D0212N-30C is designed with a self-cleaning mechanism. As the switch is rotated, a brush wipes across the contacts, removing dust and debris and ensuring that an electrical connection is maintained. This mechanism also helps to reduce the wear on the switch, allowing it to have a longer lifespan. Additionally, it helps to prevent damage to the contacts due to dust and debris buildup.

The switch is also designed to be operator-friendly. The knob has a circular pattern that is easy to grip, and allows for smooth incremental switching. This makes it easy for operators to quickly and accurately move from one contact to another. Additionally, the switch is designed to be “quasi-shorting”, which prevents accidental shorts and sparks.

The C7D0212N-30C is designed to operate with a wide range of voltage and current levels. The current rating of the switch is 125 mA at 12V. In addition to this, the contact resistance is low, typically less than 10mΩ with a maximum of 20mΩ. The dielectric strength is also high, with a withstand voltage of 250 VAC for one minute. This makes the switch suitable for a wide range of uses.

The C7D0212N-30C is also extremely reliable. It can withstand high shock and vibration levels as well as extreme temperatures. The switch is rated up to 1.2 MILLION operations, with a mechanical life of up to 10 MILLION operations. This makes it an ideal choice for telecom applications that require reliable and durable switching.

In conclusion, the C7D0212N-30C is an excellent rotary switch designed specifically for telecom applications. Its features include a self-cleaning mechanism, low contact resistance, high withstand voltage, and high reliability. This ensures that it is suitable for a wide range of applications and can withstand many years of use.
