L19B High current anti vandal switch


L19B high current anti vandal switch from Langir:

L19B high current anti vandal switch provided by Langir is one of the most intensive components in electronic products. It is a small size design and the actuator helps to limit the distance between the switch and the panel, thus minimizing damage caused by screwdrivers or other slim tools while simplifying operation.


Anti vandal switches, also known as vandalism switches, are attached to the panel using front mounting technology, further ensuring a smooth outer profile of the switch by securely hiding the retaining nut (known as the jam nut) behind the panel.

The actuator is the most frequently used part of the L19B high current anti vandal switch, and its shape design usually reduces the risk of misoperation and damage caused by potential saboteurs.
