Introduction

The 91SX48 is a new type of snap-action, limit switches commonly used in various engine control applications. It features an adjustable guide lever and it is designed to switch between two different positions. This switch is ideal for applications that require fast response and accurate timing, such as in aircraft engine control systems.

Features

The 91SX48 features a robust design and offers a variety of features. It features an adjustable guide lever with a lockout valve which helps prevent unintentional operation. Additionally, the lever has an adjustable stop for variations in speed and operation. The switch also features a floating actuator and an integrated test mode.

Application Field and Working Principle

The 91SX48 is primarily used in engine control applications. It is designed to be mounted on the engine’s valve actuator or throttle body. When the engine’s valve is opened, the switch is activated. The switch then moves from an open to a closed position, which then triggers the engine’s control system to operate.The 91SX48 works on the principle of a snap-action, limit switch. When the switch is activated, two metal contacts within the switch move towards each other. As they move towards each other, the metal contacts come in contact with each other and then, due to the repulsive force between them, they move away from each other. This results in the switch being actuated, which then triggers the control system.

Advantages

The 91SX48 offers a number of advantages over traditional snap-action, limit switches. Firstly, it is capable of providing a faster response time which is crucial in engine control applications. Secondly, it is designed for precise timing which also helps to enhance engine control performance. Lastly, it also features a lockout valve which helps to prevent unintentional operation.

Conclusion

The 91SX48 is a new type of snap-action, limit switch commonly used in engine control applications. It offers a fast response time, precise timing and a lockout valve to help prevent unintentional operation. It is an ideal choice for applications that require the highest level of precision and reliability.
