2HM1-1

2HM1-1 Snap Action, Limit Switches are constructed from a range of materials, depending on the application. As with all ready-made products, 2HM1-1 switch characteristics and parameters can not be customised and therefore have predetermined minimum and maximum load ratings that must be considered before installation and use. Below we take a look at the field of application, working principle and associated setup.

Application Field

2HM1-1 Limit Switches are designed for a range of applications, from resetting lights to emergency stop operations, and are broadly categorised into mechanical, hydraulic and electrical switches. The range of applications they can be used in includes electric motor starters, solenoids, speed monitors, electric scales, and mechanical, hydraulic and electrical emergency stopping units. Furthermore, they are used in industrial motor starters, industrial solenoids and actuators, domestic appliances and automotive applications, such as resetting lights.

Working Principle

The 2HM1-1 Snap Action, Limit Switch works by controlling the power and direction of the switch. The power is released from the switch by a spring-loaded plunger which, when released, allows the switch to reset itself, close the power circuit and open the reset switch. The reset switch, in turn, controls the direction of the current within the switch.

The switch is operated by an external force, either mechanical or electrical. The external force causes the spring-loaded plunger to be released, which then allows the switch to reset itself, close the power circuits, and open the reset switch. This is the main action of the switch.

The reset switch is usually located in the rear of the switch, and is activated by the plunger when it is released. When the reset switch is activated, it sends a signal to the power unit, which then sends the power to the next component. This signal is used to control the current and direction of the power within the switch.

Setup

The setup of 2HM1-1 Limit Switches is easy and quick. It is only necessary to ensure that the switch is properly wired to the power source(s) and that the necessary reset switch is connected. The reset switch can also be used to reset the switch automatically should the manual reset become ineffective or in the event of a power fault. This makes them very reliable in applications where manual reset may be difficult or impossible.

It is also important to ensure the correct wire size is used for the 2HM1-1 Limit Switch and that the switch is mounted in an appropriate location. The switch must be securely mounted so that it can not be moved or vibrate during operation, to ensure reliable operation.

Conclusion

The 2HM1-1 Snap Action, Limit Switch is a reliable and hard wearing switch, designed for a range of industrial, domestic and automotive applications. The setup of the switch is easy and does not require a great deal of knowledge from the installer. Further to this, the switch is designed to work reliably and reset itself automatically should the manual reset become unresponsive. It is therefore a robust and reliable switch, suitable for a range of applications.
