1EN231-S

Snap Action, Limit Switches

The 1EN231-S is a popular snap action, limit switch. It is used in a variety of applications that require control of electrical circuits. The 1EN231-S is a single pole, single throw configurable switch that is available in normally open and normally closed versions.

Application Field

The 1EN231-S is often used in various industrial, commercial and residential systems and applications. Some of the most common applications for the 1EN231-S include motor control, vehicle ignition timing control, air conditioning system control, lighting control, and access control. Additionally, the 1EN231-S can be used for controlling circuits in manufacturing processes and for controlling relays in electrical equipment.

Working Principle

The 1EN231-S snap action limit switch works by physically moving a plunger or lever when a defined amount of force or pressure is exerted on its contact point. When the contact point is depressed, the plunger or lever is triggered, pushing the contacts of the switch together, thereby completing the circuit. The contacts remain together until the pressure on the contact point is removed or the teeth of the switch return to their home position. The return of the teeth to their home position is triggered by the spring force that is preloaded into the 1EN231-S.

The 1EN231-S has adjustable actuation force, which means the amount of force required to activate the switch can be adjusted according to the user’s needs. Adjusting the force can increase the life of the device and decrease buzzing noises resulting from excessive actuation force. It is important to note, however, that too much force can cause the switch to malfunction.

The 1EN231-S is typically pre-calibrated for a given force, so users do not have to worry about setting the switch force themselves. The presence of a manual reset is also a key feature that prevents the switch from resetting itself (thus avoiding nuisance tripping and false alarms).

The 1EN231-S is also designed to be durable and reliable, with an expected life of over 10 million cycles under normal use. The switch is rated at 16A/125 VAC and is UL recognized and CSA certified.

Conclusion

The 1EN231-S is a popular and reliable snap action, limit switch that is often used in a variety of applications. The switch has adjustable actuation force, is pre-calibrated, and uses a manual reset feature to prevent nuisance tripping and false alarms. The switch is UL recognized and CSA certified and is expected to have a long lifespan of over 10 million cycles under normal use.
