Dimension: 6x6x4.3mm/0.24x0.24x0.47 inch | Button Diameter: 3.5mm/0.14inch | Withstand Voltage:AC250V | Rated Load:DC12V 50mA | Used in the fields of electronic products, household or office appliances, sound equipment, digital products, and more

Dimension: 6 x 6 x 4.5mm / 0.24" x 0.24" x 0.18" (L*W*H); Button Dia.: 3.5mm | Great for electronics hobbies & fixing anything that requires a tactile switch | High precision mechanism design offers acute operation and long service life. | These push buttons have an excellent tactile feel and work well as activation devices for microprocessor devices such as Arduino or the PI | These small switches make good contact, snap or click when pressed. The pin placement is perfect for PC boards and bread boards. On bread boards you will need to flatten the legs so they insert properly

【Usage】: One side of teg peltier(with word) is close to the heat dissipating surface (cold end), the non-word side is placed on the heat absorbing surface (hot end), the red line is connected to the positive pole, the black line is connected to the negative pole, and the power can be generated when there is a temperature difference. | 【High Reliability】: SP1848-27145 thermoelectric peltier teg module has no extra moving parts, easy to move, light weight, long life, high reliability and no pollution. | 【Note】: The temperature difference will appear on both sides of the 12 volt power supply cooling chip. When one side is cold and one side is hot, do not energize the refrigerator for a long time without a radiator. Otherwise, the inside of the refrigerator will be overheated or burn. | 【The Principle of Heat Generation】: When the thermal energy is discharged from the low temperature side through the thermoelectric power generation piece, part of the thermal energy flowing into the device does not exotherm, and becomes electric energy in the device, and outputs DC voltage and current. | 【Convenience】：The product has no moving parts, is easy to move, and is convenient for experimentation
