Technology Overview
The document discusses the perfection of piezo technology, highlighting its function and advantages. The technology is suitable for harsh environments, being water and dustproof, and is designed for both indoor and outdoor use. It features a sealed metal surface that is vandal-proof and easy to clean, with no moving parts, ensuring a long life expectancy tested for 50 million cycles. This reduces maintenance needs and service costs. The technology offers versatile mechanical configurations, allowing for manufacturing in any shape.

Applications
Piezo technology is applicable in various fields including vending machines, lifts, beverage dispensers, safety and security systems, public internet kiosks, chemical and petrochemical industries, food industry, medical equipment, mining equipment, industrial machinery, and white appliances.

Technical Data
The technical specifications include a rated voltage of 1-24 V AC/DC, rated current of 200 mA – 1A, actuation force typically between 3 - 5 N, and an operating temperature range from -20°C to +75°C. The protection system is rated IP68/69, and the switches can be illuminated with LED rings at 5VDC, 12VDC, or 24VDC.

Switch Functions
The switch operates on the piezo effect, where an external push force activates a piezo element to release voltage for switching. Three switching functions are offered: Momentary (120 Msec. Pulse), Continuous (circuit closed as long as switch is pressed, up to 6 seconds), and Toggle (switch changes position at each activation).

Product Variants
Several product variants are available, each with specific functions, materials, and dimensions:

• SMF, SBS, SMA: Momentary one shot N.O. & N.C. or up to 6 second pulse, made of aluminum or stainless steel, available in various anodize colors, with different thread dimensions.
• SBA: Programmable/Continuous N.O. or toggle (on/off), similar material and color options.
• SBR, SML: Include RGB or single LED illumination, with similar material and color options.
• BPS: Made of polyoxymethylene, with RGB LED illumination.
• Tactile: Mechanical movement with RGB LED illumination.

Custom Made Switches
Custom switches are available for unique product configurations, supported by a powerful engineering department. Options include various metals, dimensions, colors, functions, voltages, amperages, LED colors, cables, connectors, and marking methods.

Keypads and Keyboards
The document also covers a range of keypads and keyboards utilizing patented technology. These include:

• Keypads: Various configurations such as KBA, KBF, and KBH with different dimensions and output options.
• Keyboards: Full-size and reduced-size options with aluminum surface material and integrated pointing devices.

Custom keypads and keyboards offer options for surface materials, colors, functions, output types, interface connections, integrated LEDs, and marking methods.
