Touch switch is applicable for high density surface mounting. Some of them are washable after welding. It is sealed type and dustproof, and is most suitable for use in severe?environment. It is simple in circuit design. The product can be used for 100,000-10,000,000 times. The product has become a series. But touch switch also has its drawbacks, that is frequent press will make the metal dome fatigued, lose elasticity and thus lose efficacy. Touch switch can't play function individually, but must be used cooperatively with the PCB circuit board. Only in this way can it form a complete control system.
Membrane switch has many advantages: It is resistant to water, dust, oil and harmful gas erosion, and is stable and reliable in properties. It has small volume, long service life, and convenient installation. Its panel can be washed without damage of characters on it. It also has rich color and elegant appearance. Your product will obtain more distinct features of the time by using the membrane switch. Main types of the membrane switch: With rigid or flexible printed circuit board as substrate, the membrane switch panel is made with plastic (polycarbonate, polyester, etc.) faceplate with colored decorative patterns printed on it. It is installed with keys with hand feeling or not. It is a kind of electronic component integrating switch function with decorative function, and also has a new human-machine interface. Its switching circuit and connection mode of the complete appliance can be finished by welding or plug-in. It is good.
It has the characteristics of small volume, powerful function, stability and convenient operation.
