Toggle switches are electrical components that allow users to switch circuits on or off, select among multiple functions, or control the direction of an electrical current. 2TL1-1D toggle switches are designed to offer reliable switching performance and a low-cost solution for basic switch needs. They are suitable for applications that require snap-acting switching, and their external structures ensure enclosures, front-panel-mounting, and other related operations.

Application Field

2TL1-1D toggle switches are commonly used in industrial control systems, building automation, consumer electronics, communication and automation equipment. They can be used for DIN-rail or panel mounting, and are preferred for applications that require snap-acting switching, meaning short transitions between switch settings, such as on / off or momentary switches. Typical application fields include medical equipment, household appliances, automotive, and musical instruments.

Working Principle

2TL1-1D toggle switches are operated by flipping a lever on a toggle switch in order to change its settings. They use an ON-OFF or a MOMENTARY ON-OFF operation mechanism. In ON-OFF operation, the toggle switch can either be in the ON or the OFF position, where the contacts make or break the circuit, respectively. In Momentary ON-OFF operation, the contacts close once the lever is held in a certain position and are then released when the lever is moved to the opposite position.

The toggle switch lever is moved by an acuator, which temporarily depresses a small metal lever on the switch. This lever is in contact with a spring-loaded latch, when the latch is depressed, the switch lever is forced to a new position. In some toggle switches, such as 2TL1-1D, a little button can be put on the switch. This button is used to switch the switch in ON-OFF or Momentary ON-OFF operation mode.

2TL1-1D toggle switches are designed with an external structure for secure mountings for panel or DIN-rail assemblies. The secure mounting structure also prevents inadvertent operation from external forces and vibrations. Moreover, the secure mounting structure helps prevent contact bounce and arcing, which can cause contact malfunctions. Additionally, some toggle switches also have integrated surge suppressors, enabling them to withstand higher electrical voltages.

2TL1-1D toggle switches are designed for low-cost, reliable switching operations. They offer fast switching, long life span and a secure mounting structure, which makes them ideally suitable for applications in medical, automotive, building automation and other fields.
