L19A Series SPST, DPDT Anti Vandal Switch

Through a range of certifications and tests passed, the L19A Series SPST, DPDT Anti Vandal Switch makes a great choice when looking for a vandal-resistant switch with long life and high reliability.

It has a maximum switch rating of 5A/250VAC, a bushing diameter of 19 millimeters, panel cutout, and can function either 1NO1NC or momentarily, or alternately.

When it comes to the series’ material composition, the L19A Series, for the time being, is only available in stainless steel. Just like the other series, it uses Polybutylene Terephthalate or PBT as its base.

This material, however, does not in any way affect the degree of protection this series has. As for ingress protection, it has a rating of IP65, while a rating of IK09 when it comes to impact protection.

Both of these ratings add a remarkable feature to the L19A Series. An IP rating of this level ensures that dust and other foreign objects will not in any way cause damage to the switch. When it comes to moisture and water, it may not have the maximum protection, but it can withstand damage projected from a water nozzle coming from any direction. When it comes to damage that may come from external mechanical impacts, the L19A Series will not disappoint you. Even 10 joules of impact will not do any harm to this switch—that’s approximately equal to a 5-kilogram mass hitting the surface from a free fall height of 200 millimeters or 0.20 meters.

When it comes to illumination style, the L19A Series provides you multiple options. You may opt to have it non-illuminated or customize it with dot illumination or ring illumination. If you are planning to use it as a power switch, you can opt to have a power backlit symbol or combine it with ring illumination. Its actuator is flat which will require approximately 5N of operation pressure.

Your options are also almost limitless when it comes to the selection of LED color. You can choose from any of the following colors, namely, orange, red, green, blue, yellow, and white. Opting for a tri-colored switch is also possible. Presently, you can choose a combination of red, green, and blue.

The illumination voltage with a base of 1.8 V for red, yellow, and orange, and 2.8 V for blue, green, and white can be increased from 3.3 V to 220 V.

The L19A Series comes with a solder lug terminal, with a measurement of around 2.8 by 0.5 millimeters. 

In terms of the switch’s lifetime, it has a mechanical life of about 1,000,000 cycles and an electrical life of 50,000 cycles.

The L19A Series has a contact resistance of 50 mΩ Max, an insulation resistance of 1000 mΩ Minimum, and a dielectric strength of 2,000VAC. All these may come helpful when trying to diagnose and prevent contact corrosion and damaged insulation.

Just like Langir’s other series of anti-vandal switches, the L19A Series SPST, DPDT Anti Vandal Switch is also a great choice when considering something for outdoor and heavy use. Aside from being vandal-resistant, it also offers you a lot of customization options.
