Rotary Switches

The 71MBSF30-01B04N is a type of rotary switch. Rotary switches rely on mechanical position change rather than electrical connections to activate circuits. The common construction of a rotary switch consists of a spindle or rotor which acts as an input, a set of contacts which are actuated by the rotating spindle, and an actuator which is connected to the spindle for input. When the switch is rotated, the contacts are actuated to complete the circuit and form a connection from one point to another.

Application Field

Rotary switches are typically used in industrial settings, such as motor control-panels, motor starter controls, machine tool control panels and elevators. They are also heavily used in consumer products. Common applications include electrical appliances and devices such as dimmer switches, volume controls, selection switches and OFF/ON switches.

Working Principle

The working principle of a 71MBSF30-01B04N rotary switch is simple. The rotation of the spindle or rotor causes the cam-shaped actuator to change position. As the spindle rotates, the actuator will come in contact with different contacts on the switch. This will cause the contacts to close or open, depending on the position of the actuator. This in turn opens or closes one or more electrical circuits to create an on or off state.

Conclusion

The 71MBSF30-01B04N is an example of a rotary switch. Rotary switches rely on mechanical position change rather than electrical connections to activate circuits. They are typically used in industrial settings, such as motor control-panels, motor starter controls, machine tool control panels and elevators, as well as consumer products. The working principle of a 71MBSF30-01B04N rotary switch is simple, involving the rotation of the spindle or rotor and the corresponding contact changes that result from its motion.
