Rotary switches are mechanical components widely used in various electrical and electronic circuits for circuit switching, rotary selection, and control. MRX108-BB rotary switches are among the many types of rotary switches in the market. This type of switch moves in discrete increments when manually rotated and can create several positions of contact. It is therefore mostly used to switch between different circuits when a user manually rotates it. 

The MRX108-BB switch is a miniature SPDT (Single Pole Double Throw) rotary switch that uses a spring and ball detent torque mechanism with a clutch on the drive shaft. It is made of insulating material with plastic knob, actuator and base. The contacts are silver plated, while the insulators are formed ceramic materials. The mechanical strength rating of the contacts and terminals is 2 amps to 5 amps at 110VAC/DC. It has an operating temperature of -20°C to 125°C, a total operating life of 5,000 cycles (100° rotation), and is rated IP67 (dust-tight and waterproof). 

The MRX108-BB rotary switch is housed in an industry standard 1.2”x1.7”x0.87” package. This makes the switch suitable for many application areas. For example, it can be installed in a space-constrained environment on a wide variety of applications, such as: communication devices, computers, office automation products, industrial control devices, telecommunication equipment, meters, and home appliances.

The working mechanism of a rotary switch is relatively simple. When the user turns the knob, contacts in the switch close an electrical circuit. With the MRX108-BB switch, when the shaft is rotated clockwise the switch is set in the “off” position and no connection is made between the two terminals. When the shaft is rotated counter-clockwise the switch is set in the “on” position and the two terminals are connected.

The rotary switch is most commonly used for manual switching in a variety of industrial electronic control applications. However, the popularity of the switch can also be attributed to its low cost, chemical stability, and long life expectancy. In addition, the MRX108-BB switch can be used in any environment due to its moisture and dust-resistant construction.

Overall, MRX108-BB rotary switch is a reliable, cost-effective and versatile switch suitable for many applications. Its miniature size and precision design makes it suitable for operations within confined spaces while its high functioning resistivity ensures a long functional life. Finally, its versatile design makes the switch suitable for industrial use, including process control, machine control, automation, and office equipment.
