• Introduction and operating principle of Micro Switches

  2020 / 01 / 07

  Introduction and operating principle of Micro Switches A Micro Limit Switch is a contact mechanism with a small contact interval and a fast-acting mechanism. It uses a specified stroke and a predetermined force to perform the switching operation. It is covered with a housing. There is a switch with a driving rod on the outside because the contact distance It is relatively small, so it is called a micro switch, also called a sensitive switch. The electrical text symbol is: SM. working principle External mechanical force acts on the action through transmission elements (pins, buttons, levers, rollers, etc.) Waterproof Micro Switches On the reed, an instantaneous action occurs when the action reed is displaced to a critical point, so that the movable contact and the fixed contact at the end of the action reed are quickly turned on or off. When the acting force on the transmission element is removed, the action reed generates a reverse action force. When the reverse travel of the transmission element reaches the action critical point of the reed, the reverse action is instantaneously completed. The micro switch has a small contact distance, a short action stroke, a small pressing force, and a fast on-off. The speed of the moving contact has nothing to do with the speed of the transmission element. 2 types edit Micro Switches Types, with hundreds or thousands of internal structures. There are ordinary type, small size, and ultra-small size according to volume. According to protection performance, there are waterproof, dustproof, and explosion-proof types. Single type, double type, multi-connection type. There is also a strong disconnect micro switch (when the switch's reed does not work, external force can also open the switch); according to the breaking capacity, there are ordinary type, DC type, micro current type, high current type. According to the use environment, there are ordinary type, high temperature type (250 ℃), ultra high temperature cer

  2019 / 12 / 26

  New Product IP68 Waterproof Push Button Switch PF Push Button Switches is an extension and advanced version of the PA Waterproof Push Button Momentary Switch series. It has SPST function and has a round and high-level button cover to choose from. The style is very diverse. In the future, we can also customize the font or pattern. The PF series is a lightning protection switch that can be used in harsh environments. The housing is made of plastic and sealed to IP68 specifications (one meter deep; one hour). The PF miniature illuminated Push Button On Off Switch has increased the positioning design, making the CAP more directional, the LED dots transmit light, and the diameter reaches 3.0mm, which increases the range of illumination. PF miniature illuminated push-button switch can also be designed with wire, more close to the needs of users. Used in lighting, computer peripherals, communications, medical equipment, industrial control, marine ...

• Classification and Detailed Introduction of Tact Switches

  2019 / 12 / 25

  Classification and Detailed Introduction of Tact Switches The switches are mainly divided into the following types, Tact Switches, Toggle Switches, Key Switches, direct key switches, power switches, Rocker Switches, etc., Each type is described in detail below. What is a tact switch? Tact switch It is an electronic switch, which can be turned on by lightly pressing the switch button when in use. When the hand is released, the switch is turned off. The internal structure of the switch is turned on and off by the force of a metal spring. The tact switch is composed of: insert, base, shrapnel, button, and cover. The waterproof tact switch adds a layer of polyimide film on the shrapnel. Tactile switches are widely used in home appliances due to their low contact resistance, crisp touch feel, complete height specifications, etc., such as: audio and video products, digital products, remote controls, communications products, household appliances, Security products, toys, computer products, fitness equipment, medical equipment, banknote detectors, laser pen buttons, etc. But the touch switch also has its shortcomings. Frequent pressing will make the metal shrapnel fatigue and lose elasticity and fail. Therefore, most of the buttons of electrical appliances are now directly replaced by conductive rubber or pot switch hardware springs, such as computer keyboards, TV remote controls, etc. Regarding the pin connection of the five-pin tact switch: two pins are in a group, the four corners are for more stable
