Snap Action, Limit Switches

AH73524569-A is a snap action, limit switch. It is an electrical switch in which a set of electrical contacts open and close as a result of a mechanical spring mechanism that is actuated by the motion of the actuator. Snap action switches, also known as snap action limit switches, are used in a variety of electronic components and home appliances. The ability to react quickly and accurately to mechanical motion makes them suited for applications with particularly precise control dynamics and those in which there is a need for a reliable and repeatable switch.

Working Principle

The spring mechanism of the AH73524569-A is actuated by an actuator, either directly or indirectly. Directly actuated switches are triggered by the mechanical action of a body, button, plunger, or lever, while indirectly actuated switches are triggered by electromagnetic fields, vibration, or other pressure sources. When the actuator is pushed within the switch, the spring mechanism engages and the contact points open or close. After the actuator is released from the switch, the spring mechanism disengages and the contact points reset to their original position. The AH73524569-A is designed to activate within a certain range of motion, outside of which the switch will not change state.

Application Field

Due to their repeatable and reliable operation, AH73524569-A snap action switches are used in applications ranging from consumer appliances like washing machines and dryers to industrial applications like medical and manufacturing machinery. Some examples of their uses include mechanical limit applications in load control, conveyor systems, motor control, and integrated circuit board production, as well as other motion or position controlled systems. They can also be used in automotive, telecommunications, and navigation systems.

AH73524569-A snap action switches are built to withstand high temperatures, extreme pressures and shock, and wet and dry contact operation. They can be used in hazardous environments and hazardous locations thanks to their UL/cUL certified variants, and their double insulation, over-protection, and installation flexibility ensure safe operation without the risk of electric shock or shorting out. Furthermore, they are compact, lightweight, and easy to install.
