12*12 SMD Tact Switch

For 12×12 flick switch, its size specification is 12 mm in length and width, and this size of switch is usually used in occasions that need to withstand higher current, high voltage, and other special working conditions, such as large home appliances, instrumentation, industrial controllers, and other fields.

Specifically, the 12×12 light touch switch consists of an insert, a base, a shrapnel, a pushbutton, a cover, and so on. When the button is pressed, the button moves downward, causing the contact reed or conductive rubber block to contact the solder lug, forming a pathway, thus realizing the opening of the circuit. And when the pressure is withdrawn, the shrapnel returns to its original state, the switch is disconnected, and the circuit is also disconnected.

In addition, the operating force of a light-touch switch is related to the state in which the reed is in. The starting force is proportional to the compression distance of the reed, and when the reed is compressed to a certain degree (e.g., 50% to 70%), the operating force is suddenly reduced and accompanied by a “ticking” sound. This design provides a clear tactile feedback when the switch is operated.

Basic Parameters

The rated load spans from 10μA 1V DC (ideal for low-current scenarios) to 50mA 12V DC (standard operating conditions), adapting to diverse circuit requirements. Operating force options are versatile, including 100±30gf, 160±50gf, 250±50gf, 260±50gf, as well as larger force specifications to match different tactile feedback preferences. Most models boast a mechanical service life exceeding 100,000 operating cycles, with high-performance waterproof variants extending to 1 million cycles for long-term dependability. Operating temperature ranges vary by model: common ranges include -20℃ to +70℃, -25℃ to +70℃, and -40℃ to +85℃, ensuring stable performance in indoor, outdoor, and industrial environments. Contact resistance is optimized for consistent current transmission—most models feature ≤100mΩ, while high-precision versions achieve ≤50mΩ. Installation height options cover 4.3mm to 21mm, catering to the space constraints of various electronic assemblies.

Product Features

Engineered for seamless integration into automated production lines, most 12*12 SMD Tact Switches adopt tape-and-reel packaging, compatible with automatic placement machines to enhance assembly efficiency and reduce labor costs. Protection performance varies by model: standard variants offer basic dustproof capabilities, while specialized waterproof models reach IP67 rating. These waterproof designs employ a secure snap-fit between the cover plate and base, effectively preventing water and dust ingress to avoid conduction failures in harsh conditions. Constructed from high-quality plastic and copper materials, the switches deliver low contact resistance and excellent insulation properties. The optimized button structure ensures smooth pressing with clear "click" tactile feedback, allowing users to confirm successful activation instantly. Many models undergo rigorous salt mist, low-temperature, and heat resistance tests, and hold CE and ROHS certifications, guaranteeing reliable performance across diverse operating environments.

Because of their advantages of low contact resistance, precise operating force error, and diversified specifications, flick switches are widely used in electronic equipment and white goods, etc. 12×12 flick switches, as one of the specifications, are also suitable for a variety of applications:

Large home appliances: such as refrigerators, washing machines, air conditioners, etc. These appliances usually need to withstand higher current and voltage, so they need to use larger specifications of flick switches.

Instrumentation: such as multimeters, oscilloscopes and other test equipment, these equipment requires high accuracy and reliability of the switch, 12 × 12 flick switch can meet these needs.

Industrial controllers: such as PLC (programmable logic controller) and other automation equipment control systems, these controllers need stable and reliable switches to control the operation of the equipment.

In addition, 12×12 tactile switches are widely used in communication products, computer products, fitness equipment, security products and other fields. In these applications, the flick switch not only provides the function of circuit on/off, but also enhances the overall user experience of the product through its compact size, exquisite appearance and clear hand feedback.
