What is a Rotary Switch?
Rotary switch is a type of electrical switch that uses a rotating mechanism to select a number of positions or settings. It is usually used to control and configure electrical circuits.
How Does the Rotary Switch Work?
Rotary switches usually feature a circular or semi-circular housing with multiple electrical contacts and a rotary button or shaft to connect these contacts together. These positions are usually indicated by markings around the switch hosing. These positions correspond to different electrical configurations and are used in applications where you need to choose from a variety of options.
Inside the switch, there are electrical contacts connected to different positions. When the switch is rotated, the different contacts form physically open electrical circuits. These switches come in various configurations such as single pole, single terminal (SPST), double pole, double terminal (DPDT) or more complex configurations to suit different circuit requirements. Some of them have multiple decks, which allows for more complex switching.
What are the Areas of Use of Rotary Switches?
Rotary switches are versatile components used in electrical and electronic circuits and offer a practical and reliable way to change the configuration or function of a device. They are usually designed for robustness and long-term reliability, which makes them suitable for industrial and heavy-duty applications.

What is a Coded Rotary Switch?
Coded rotary switches are used to select one of the multiple options. This device is similar to a rotary switch, where its outputs are encoded in binary to reduce termination requirements. Coded rotary switches have several positions that can be activated by a rotary shaft. They are mounted on printed circuit boards (PCBs) to control their output. Some switches are moved with a screwdriver, while others contain shafts that are rotated manually. They can be designed to rotate 360° continuously, or they can stop in predetermined positions as they rotate. Coded rotary switches offer many advantages, such as long mechanical service life, the number of positions, and the ability to rotate 360° or stop in predetermined positions. They can also be used in applications such as Two-Way Radio Devices, Aircraft Transponders, Medical Equipment and Industrial Automation Equipment.

What is a Keylock Switch?
A keylock switch is a type of electrical switch that is operated by rotating a switch. It is usually used to control access to electrical devices or systems, such as machines, electronic equipment or security systems. It provides a physical barrier to prevent the random or unauthorized operation of the equipment. The switch can usually be rotated to select the desired position.
How Do Keylock Switches Work?
Key Mechanism: Keylock switches have a cylindrical or tube-shaped key. The switch usually has a unique pattern that matches the internal mechanism of the keylock switch.
Lock Mechanism: There is a locking mechanism inside the keylock switches that activates and deactivates depending on the position of the key. When the switch is rotated, it moves the internal parts to allow or block the flow of electric current.
Contacts: The switch has electrical contacts, and these contacts turn on or off the circuit connections. These contacts are controlled by the position of the switch. When the switch is turned to “ON” position, the contacts are closed, allowing the electric current to flow. In the ”OFF” position, on the other hand, the contacts are opened and the current is cut off.
Multiple Positions: Keylock switches usually have more than one position or mode, each representing a different function or state. For instance, there may be positions such as ”off“, ”on“ and ”emergency stop”.
Security and Access Control: One of the main purposes of keylock switches is to provide security and access control. They require a physical switch to operate the switch, to restrict unauthorized people from manipulating the connected equipment or systems.
Where are Keylock Switches Used?
Some applications they are commonly used in are:
- Audio/visual equipment
- Safety devices
- Industrial control devices
- Kiosk controls
- Electrical household goods
- Medical equipment
- Security applications
- Personal vehicles
