The light touch switch is also called the key switch. * It has been used in Japan [called the more sensitive switch] for a long time to apply pressure to the operating direction of the switch in order to adapt to the precondition of the operating force. The switch is closed when the working pressure is removed. Its internal structure is connected by the change of the bearing force of the metal shrapnel. The light touch switch is composed of insert, base, spring plate, key and back cover plate. The moisture-proof light touch switch adds a layer of polyimide film on the spring plate

The light touch switch has the advantages of small contact resistor load, accurate operating force deviation, diversified specifications and models, etc. It has been widely used in electronic products and household appliance brands, such as: audio-visual products, electronic products, controllers, communication equipment, electrical products, security equipment, small toys, computer products, fitness equipment, medical equipment, currency verification pens, laser pen function keys. As the light touch switch directly replaces the environmental standard (the applied pressure is lower than twice the elasticity/natural environment temperature and humidity standard and its electrical performance), large machinery and equipment as well as the keys with long load with conductive rubber or metal spring of pan switch, such as medical devices, TV remote controllers, etc. Pin problems related to five pin touch switch: two pins form a group, four pins are connected and disconnected when appropriate pressure is applied to the switch body, and the fifth pin is the function of grounding device.

[Detection switch] What should be paid attention to when selecting the detection switch for installation?

Detection switch, a kind of position switch (also known as travel arrangement switch, positioning switch), is a common electrical product of low current cam controller. The production and processing kinetic energy components shall be used to impact the isolator to complete the connection or disconnection of the control circuit to ensure a certain control purpose. In general, this switch is used to limit the position or schedule of molecular thermal exercise, so that the industrial equipment for sports and fitness can automatically stop, repeatedly exercise, speed change exercise or automatic back and forth sports and fitness according to a certain position or schedule.
