4HS201-118

Snap Action, Limit Switches

The 4HS201-118 is a versatile device used in a wide array of sensing applications. This snap action microswitch delivers robust performance and reliable operation in short-cycle and low-cycle operations. Utilizing a snap action mechanism and a metal alloy, 4HS201-118 can remain in the position you want it to and keep tensions balanced, while not sacrificing its precision. This particular model features a trigger lever, allowing the user to easily engage or reset a particular state within the switch.

The 4HS201-118 is a two-pole single-throw (SPST) switch featuring a short travel and quick action. This model has a consistent repeatability, contact pressure, and fast operational time. Moreover, the 4HS201-118 has an adjustable actuation lever, offering additional control and flexibility. It also has an IP rating of 67 and an operating temperature range of -40 to +85 degrees Celsius (-40 to +185 Fahrenheit). With a silver plated contact and silver-nickel alloy construction, it offers excellent switching performance.

The 4HS201-118 has a range of potential applications as it can be used to open or close a circuit or provide a switchable output to a logic circuit. It is commonly used in industrial automation and process control applications due to its reliability and small size. This device can also be used in commercial and residential HVAC systems as well as burners, stoves, boilers, and other heating and cooling appliances. Additionally, 4HS201-118 is well-suited for use in vending machine, gaming systems, solar array power converters and other motor control applications.

Working Principle

The 4HS201-118 utilizes a snap action mechanism to open or close a circuit. This snap action is triggered when the electrical output is applied to a reset will create a magnetic field which then moves a slide from one side to the other. The slide rapidly moves to either the open or closed position, resulting in rapid actuation of the switch.

The 4HS201-118 also utilizes a metal alloy construction. This combination of materials possesses excellent durability and offers exceptional contact pressure. Thanks to the switch’s two-pole single-throw operation, contact closure is assured ensuring peak performance and a consistent repeatability. It is also is highly resistant to industrial and environment abuse, making it an excellent choice for a variety of applications.
