    FAQs

    Our 12mm Anti-vandal Switch is a compact, rugged pushbutton designed specifically to withstand mechanical abuse, harsh environments, and vandalism. Its key differentiators are its small 12mm panel cutout, robust stainless steel construction, and durability ratings including 200,000 mechanical cycles and 50,000 electrical cycles at 2A 36VDC.

    A latching switch maintains its state after being actuated. Press it once to turn ON (it stays ON), press it again to turn OFF (it stays OFF). This is opposed to a momentary switch which only remains active while being pressed. Latching is the most common configuration for the 12mm Anti-vandal Switch.

    The switch is rated for 2A at 36VDC with a mechanical life of 200,000 cycles, electrical life of 50,000 cycles, contact resistance of 50mΩ max, insulation resistance of 1000 MΩ min, and dielectric strength of 2,000VAC. Operating/storage temperature range is -20°C to +55°C.

    The switch is available in three illumination configurations: Non-illuminated (no LED), Ring-illuminated (LED ring around the actuator), and Dot-illuminated (center dot LED). LED colors include Red, Yellow, Orange, Blue, Green, and White with base voltages of 1.8V @ 20mA for warm colors and 2.8V @ 20mA for cool colors.

    The standard L12 is primarily rated for DC applications (2A 36VDC). For AC applications, please contact our engineering team for specific recommendations or alternative switch models that better suit your AC voltage requirements.

    With IP65/IP67 ingress protection ratings, the L12 is well-sealed against dust and water ingress. The stainless steel body and actuator resist corrosion, and the operating temperature range of -20°C to +55°C ensures reliable performance across diverse environmental conditions.

    We offer several actuator styles including flat, domed, and raised profiles. The actuator can be customized in various finishes such as brushed stainless steel, black anodized, or with custom engraving/printing for branding purposes.

    The standard panel cutout is 12mm diameter for a 12mm mounting hole. While the cutout size is standardized, we can work with you on custom bezel designs and mounting solutions for unique applications. Contact our engineering team for customization options.

    Our switches carry CE, RoHS, IP65, and IK09 certifications, meeting international quality and safety standards. We offer OEM/ODM services, competitive MOQs, global logistics support, and responsive technical assistance – making them ideal for worldwide distribution and brand integration.

    Use our Part Number Configurator above to define your exact requirements: select function type (latching/momentary), illumination (none/ring/dot), LED color, and terminal type. For applications requiring special ratings or certifications, contact our technical team for personalized guidance.

    FAQs

    A piezoelectric switch is a type of switch that operates based on the piezoelectric effect. When pressure is applied, it generates a voltage that can be used to perform a function.

    The principle of the piezoelectric effect is based on certain materials’ ability to generate an electric charge when subjected to mechanical stress, such as pressure or vibration. This effect is reversible, meaning that the same materials can also deform in response to an applied electric field.

    Piezoelectric switches are used in a wide variety of applications, from consumer electronics and industrial machinery to medical devices.

    Some of the key benefits of piezoelectric switches are their durability, versatility, and energy efficiency.

    The future of piezoelectric switches is promising with technological advancements leading to even more efficient and versatile devices. The energy harvesting feature could also contribute to sustainability in electronics.

    Some common materials that exhibit the piezoelectric effect include quartz, Rochelle salt, and various ceramics.

    FAQs

    A capacitive touch switch is an electronic device that detects touch input through a touch-sensitive surface using changes in capacitance. It allows users to control functions or operations by simply touching the surface.

    Capacitive touch switches work by creating an electric field on a touch-sensitive surface using electrodes. When a conductive object, like a finger, comes into proximity or makes contact, it disrupts the electric field, changing the capacitance. This change is detected, and the switch triggers a specific action.

    Yes, capacitive switches typically require a power source to operate. They are connected to a power supply to function correctly. The power consumption is generally low, making them energy efficient.

    Yes, capacitive touch switches can be beneficial for people with disabilities. They offer a touch-sensitive interface that can be easier to use for individuals with limited dexterity or mobility.

    Capacitive switches are known for their low power consumption. The technology relies on changes in capacitance, which requires a minimal amount of power. This makes them suitable for battery-powered devices and energy-efficient applications.
