4.5*4.5 Tact Switch Side Insert 3P

4.5x4.5 tactswitches‘ Structure

The flick switch has a length and width dimension of 4.5 x 4.5mm and is designed with a side-inserted 3-pin design, which is convenient for mounting and connecting on circuit boards and improves the flexibility and convenience of installation.

Internal construction:

Base: usually made of reinforced PA66 or LCP etc., with good mechanical properties and heat resistance.

Shrapnel: made of imported stainless steel covered with silver, ensuring good conductivity and durability.

Buttons: Also made of reinforced PA66 or LCP etc., comfortable and durable.

Cover plate: optional materials such as SP12 or H62 to meet different salt spray test requirements.

4.5*4.5 tactile switche’  Characteristics

tact switches' Electrical Performance:

Rated load: usually DC 12V 50mA, suitable for low voltage, small current electronic equipment.

Contact impedance: usually less than or equal to 100mΩ, ensuring good conductivity.

Insulation impedance: usually greater than or equal to 100MΩ, with high insulation performance.

Voltage strength: e.g. AC250V (50Hz/1minute), which ensures the safety of the switch in a high-voltage environment.

他怕switches‘ Mechanical properties:

Operating force: according to different application requirements, the operating force can be done in a variety of specifications such as 100gf, 160gf, 260gf, etc. The lighter the force the lower the pressing sound and the higher the service life. However, it should be noted that switches with too high a height may not be suitable for light acrylics, because there may be no hand feeling when pressing.

Stroke: Usually 0.12±0.05mm to ensure the sensitivity and reliability of the switch.

Service life: up to 100,000 times or more for high durability.

touch switches' Environmental adaptability:

Welding Temperature Resistance: Usually can withstand high temperature welding of 250±5°C, some products can even withstand high temperature of 280°C, adapting to the welding process of automated production line.

Use temperature range: generally between -25°C and 85°C (some products are -25°C to 70°C), suitable for electronic equipment in different temperature environments.

Use of humidity: usually requires no more than 85% RH (at 40 ° C), to ensure the stability of the switch in a humid environment.

Environmentally friendly features: All use environmentally friendly high temperature resistant materials that meet EU ROHS requirements, which are environmentally friendly and safe.
