71AF30-02-1-10S

Introduction

A rotary switch is a switch that is operated by turning a knob, wheel or handle to connect or disconnect two circuits. The 71AF30-02-1-10S is an example of such a switch. This article will provide an overview of the 71AF30-02-1-10S application field and working principle.

Application Field

The 71AF30-02-1-10S is a medium sized single pole double throw (SPDT) rotary switch. This switch can be used in a variety of applications such as test and measurement equipment, electronic toys, and industrial instrumentation. Additionally, this switch is suitable for use in 110VAC/220VAC applications, as it has a insulation of 2.5KV.

Working Principle

The 71AF30-02-1-10S works by using a movable contact to selectively connect one of two stationary contacts to a single common contact. When the switch is in its off position, the movable contact is not connected to either of the stationary contacts. When the switch is turned on, the movable contact is moved to connect with one of the stationary contacts. This completes a circuit and allows electrical current to flow.

The switch is actuated by a rotatable knob or wheel on the outside of the switch. The rotatable action of the knob or wheel rotates the movable contact, moving it from its off position to one of the on positions. When the switch is moved to a new position, the movable contact is disconnected from its previous stationary contact and connected to the next stationary contact. This ensures that no two contacts are ever connected at the same time within the same switch.

Conclusion

The 71AF30-02-1-10S is a medium sized SPDT rotary switch that can be used in a variety of applications. The switch works by using a movable contact to selectively connect one of two stationary contacts to a single common contact when the switch is turned on. Switching is accomplished by rotating a knob or wheel on the outside of the switch, which moves the movable contact to different positions.
