Snap Action, Limit Switches

The AH75544569-A is a type of snap action, limit switch. It is used to detect the presence or absence of an object and is often used in conjunction with mechanical actuators such as levers, push buttons, and pilot valves.

Application Field

The AH75544569-A is a versatile device that can be used in a variety of applications. It is commonly used to detect limit position of mechanical actuators, detect actuation forces and motion, and to provide position feedback in control systems. It can also be used to detect open and closed positions of devices such as doors, windows, and machine guards. Furthermore, due to its robust design, the AH75544569-A is suitable for both indoor and outdoor applications.

Working Principle

The AH75544569-A features a snap action mechanism which is a combination of mechanical and electrical parts. The mechanism consists of a contact arm and a leaf spring. The contact arm is spring-loaded and moves back and forth between two contact points. The leaf spring acts as a counterweight and helps to maintain the contact arm in a balanced position. When the contact arm is subjected to an external force, it is pushed away from one contact point, thereby causing it to “snap” shut the other contact point.

When the contact arm reaches the other contact point, an electrical connection is made, thus triggering the switch. The connection is held until the external force is removed and the contact arm snaps back to the original position. The contact arm is also designed to ensure that an electrical connection is not made until the contact arm has completely snapped shut, thus avoiding any potential short circuits caused by incomplete actuation.

Specifications

The AH75544569-A has a maximum contact rating of 8A/250V AC and a maximum actuation force of 10N. It is available with a variety of mounting options and can be configured for either normally open (NO) or normally closed (NC) operation. The switch is also designed to be dust and splash-proof, making it suitable for use in a variety of applications.

Conclusion

The AH75544569-A is a snap action limit switch designed for use in a variety of applications. It features a snap action mechanism for reliable actuation and it can be configured for either normally open (NO) or normally closed (NC) operation. It is rated for 8A/250V AC and has a maximum actuation force of 10N. Due to its versatile design, the AH75544569-A is suitable for both indoor and outdoor applications.
