4HS146-220

Snap action, limit switches are electrical components used to create an electrical connection when a predetermined amount of force is applied. They are used in a wide variety of applications, from simple industrial automation to complex robotics.The 4HS146-220 snap action, limit switch is a robust, low- cost alternative to higher-end versions, designed for more demanding applications. It features an integral actuator which senses when a predetermined amount of force is applied and then causes the contact points within the switch to close. This ensures the presence of an electrical connection between the two points.The 4HS146-220 features a single- pole, double-throw (SPDT) design, with both normally open and normally closed contacts. This versatility makes it useful in applications that require a reliable electrical connection when a certain amount of force is applied.The 4HS146-220’s integral actuation mechanism must be correctly applied during installation or the switch will not function correctly. Actuation force can be adjusted using the integral potentiometer.The 4HS146-220 includes a large variety of options, including a 1, 2, 4 or 6 pole design, as well as paddle, roller and roller lever actuators. This flexibility makes the switch ideal for a range of applications, from small-scale industrial automation to large-scale robotics.When used for applications that require the utmost accuracy, the 4HS146-220 features a differential microtravel adjustment that ensures that the switch’s electrical connection is always reliable and robust. The microtravel adjustment also allows for a steadier actuation and reduces the chances of contact chatter even in the harshest of environments.Overall, the 4HS146-220 snap action, limit switch provides a robust, low-cost solution for a wide variety of applications. Its versatility, adjustable actuation force and microtravel adjustment allows for precision and accuracy, and its sturdy construction ensures a long service life.
