114HM1-3

Snap Action, Limit Switches

The 114HM1-3 is a type of snap action limit switch series manufactured by the world’s leading brand EPICTM Engineering. It is a versatile two-pole switch with a wide array of applications and is distinct from other limit switches due to its robust construction and high compatibility.

Application Field

The most common application field of the 114HM1-3 series is automated control systems, specifically when a limit switch is required to activate a certain process. Depending on the type, the switch could require a simple on / off action to activate a cycle or be part of an extended control system. Furthermore, they can also be used to detect the presence or absence of objects. Therefore, the 114HM1-3 series have been found in assembly systems, conveyors, packaging systems, security doors and even in medical equipment.

Working Principle

The series 114HM1-3 is composed of two main parts: the actuator and the base. The actuator consists of two contact blocks; one normally open (NO) and one normally closed (NC) with each also having a slow-break variant. When the switch is activated by engaging with either the NO or NC contact block, depending on the application, the actuator will cause the switch to snap open or closed. To ensure that the actuator does not snap too much and cause a false trigger, the EPICTM design uses a unique integral snap-action feature.

The base is composed of a variety of housing and mounting configurations, to suit almost any application. These include PCB (Printed Circuit Board), panel mounting, top/end/angle mounting, and air gap versions. The usual material used for the base is thermoplastic and brass with various materials depending on the intended use. The base also features a mechanical latching mechanism and a gold-plated contact base. The design of the base ensures that the switch remains stable and secure even with extreme conditions and physical contact.

Conclusion

The 114HM1-3 series from EPICTM Engineering is a versatile two-pole switch, offering a wide array of applications and unique design. Its application field ranges from automated control systems to detecting the presence of objects and its robust construction ensures its stability even with extreme conditions. It is an economical and reliable solution for an array of needs and is easy to install.
