Snap Action, Limit Switches are widely used in the application of mechanical-electrical interlock and controlling on a variety of automation machines. They are usually composed of movable elements, fixed elements, contacts and holding latch. The positioning action between these two elements produces the activation of the switch.

The most common type of snap action, limit switch utilizes a lever and a plunger as the moving and fixed elements. When the plunger is pressed, the lever contacts the switching terminal and the switching action is completed. The basic structure of snap action, limit switch consists of a K terminal, N terminal, a PA terminal, and a PB terminal. The K terminal plays the role of totalize reset; the N terminal is used as the normally open contact when the moving element is in a certain position; the PA terminal is used as the normally close contact when the moving element is in a certain position; and the PB terminal is connected to the actuator.

The working principle of 83278801 snap action, limit switch is relatively simple. When the actuator is activated, the constructed lever is pushed and the normally open contact is connected. When the actuator is deactivated, the switch is released and the normally close contact is connected. The switching action of the 83278801 switch is suitable for applications with limited working space. With this switch, the totalize reset or K terminal can also be used for resetting purposes, offering increased flexibility in its applications.

The 83278801 snap action, limit switch is widely used in many industry automation processes. It is usually used in controlling some precise mechanical operations, providing precise control signal to the relay and control devices. Furthermore, its signal can be used to initiate various measurements such as counting, positioning, transmission, and signal recognition. In addition, it is also suitable for controlling door locks, position switches of a starting motor, fluid level controllers and other machines that require precise position control.

The 83278801 snap action, limit switch can be used in motor-controlled systems and flow transmitting systems. In motor-controlled systems, it changes the motor’s rotational direction, providing signals to increase and decrease the speed, or to void the start or stop of the motor. In flow transmitting systems, the switch monitors the start and stop of the flow and triggers signals for the purpose of controlling the speed, flow direction, and maintaining the balance of the pressure.

In conclusion, the 83278801 snap action, limit switch is a versatile and reliable switch used in a variety of applications in the field of automated systems. By combining the movable and fixed elements, contacts, and holding latch, it produces precise and reliable switch acting, making it essential in many industry applications.
