<h2>Snap Action, Limit Switches</h2><p>Snap action, limit switches are electromechanical devices typically used to detect the presence or absence of an object. These switches, also known as limiters, are available in many forms, such as push-button, rocker, flip-flop, rotary, and plunger styles. Depending on the type, the switches can be used to detect the position of the object being detected, as well as the speed, acceleration, or force of the object. The 12HR4-S is a common type of limit switch used for a variety of applications. </p><h3>12HR4-S Application Field </h3><p>The 12HR4-S is a three-pole limit switch, with a ratings of 10A 125/250 VAC, and a various combination of actuator heads, to meet the requirements of many different applications in industry. Typical applications include HVAC, air compressors, and industrial machinery, machinery control, conveyor control, robotics, and automation, to name a few. The switch features an alloy steel roller tip, with a black oxide finish, for corrosion protection. Its housing is made from zinc die cast, for enhanced durability and reliability.</p><h3>12HR4-S Working Principle</h3><p>The 12HR4-S switch works on the principle of magnetically actuated contacts. When it is subjected to the correct intensity and type of magnetic field, two or more contact points, attached to the switch, move close enough together to complete a circuit. This is known as a “trip point”. Upon reaching a trip point, the circuit is completed and the device either turns on or off depending on the type of switch.</p><p>The 12HR4-S switch can be set up in a variety of ways for different applications, such as emergency stops and start/stop features. For example, the switch can be set up to turn on when the magnetic field is present and off when it’s not. In another configuration, the switch can be used as a switch that turns on when the magnetic field is absent and off when the magnetic field is present.</p><p>The 12HR4-S switch is a reliable, cost-effective way to detect and control the speed, acceleration, or force of objects. With its wide range of applications, and its ability to be configured several ways, this switch is a great choice for those looking for an efficient and effective limit switch.</p>
