L19B Series Big Current Anti Vandal Switch

Another exceptional series from Langir’s long list of anti-vandal switches is the L19B Series Big Current Anti Vandal Switch. It has a compact design and suits best for small or limited areas.

From the name itself, you know that this series can be used when a big electric current is in consideration. The L19B Series has multiple maximum switch rating options starting at 2.5A for Alternating Current Voltage with the highest at 21A/250VAC, 120VAC. If used with Direct Current Voltage, the L19B series is available at two maximum switch rating options at 0.6A/125VDC and 0.3A/250VDC.

It has a quick terminal option which measures around 6.35 millimeters by 0.8 millimeters. The L19B Series also offers multiple function options. Two of these include momentary and alternated which can be subdivided into 1NO (SPST), 1NC (SPST), and 1NO1NC (SPDT).

It has a contact resistance of 25 mΩ maximum and an insulation resistance of 100 mΩ maximum. It has a dielectric strength of 1000Vrms, 50/60Hz for one minute between non-consecutive terminals, around 1500Vrms, 50/60Hz for one minute when between non-current carrying metal parts and each terminal, and the same strength when between ground and each terminal.

Other helpful information you can find about this series is its shock and vibration resistance which you can find in detail in the technical data presentation.

It is suggested that this switch be placed in an environment with an ambient temperature of -25 °C up to 85 °C.

When not in use, it is expected that the switch will last up to two million cycles and will only last for fifty thousand cycles when operated.

As to its body and material composition, the L19B Series has a contact material made of a silver alloy, and its actuator and body made of stainless steel. This makes the L19B Series dustproof and waterproof because of its ingress protection at IP65. Additional protection, which is the impact protection, makes this series safe from unintended mechanical forces equivalent to ten joules.

If you are considering customization, the L19Series can also be made according to your illumination style and color preferences. You may opt for dot or ring illumination, and choose from the six available colors namely, red, yellow, orange, white, green, and blue. All these LED colors are available at different voltages, which you can see in detail in the order code tab.

Due to its multiple rating options, the L19B Series Big Current Anti Vandal Switch makes a great option when looking for an anti-vandal switch that can handle a heavy current. It does not only offer smart functionalities but also quality.
