Key switch picture_Key switch model Daquan

The key switch is generally composed of a handle, a slide plate, a movable contact piece, a fixed terminal, a compression spring, a shell, etc. It controls the on and off of the movable contact and the fixed terminal contact by pressing the switch handle. There are two types of key switches: single key type and multi-key combination type. The one-button key switch is generally used as a power switch in a TV set, and it is divided into a self-locking and self-resetting type (this switch is pressed once to turn on self-locking, and then pressed again to disconnect and reset) and a non-locking type (no lock). Lock, connect when pressed, reset when released) two structures. Different structures have different functions of key switches, so there are various types of switches. Today, I will show you several commonly used key switch models.

Dongguan Ou Gao Electronics Co., Ltd. is a professional company dedicated to high-quality electronic and electrical switches and sockets. The company has accumulated many years of rich marketing experience and has many mature high-quality products. Switch products mainly include key switches. The key switch mainly refers to the light touch key switch, also known as the light touch switch. The key switch is an electronic switch, which belongs to the category of electronic components. When used, the switch function is closed and turned on by applying pressure to the operating direction of the switch to meet the conditions of the operating force. When the pressure is removed, the switch is turned off. Force changes to achieve on-off.

The key switch has the advantages of small contact resistance load, accurate operating force error, and diversified specifications, and has been widely used in electronic equipment and white goods. Because of the environmental conditions of the key switch (elastic force with pressure less than 2 times/environmental temperature and humidity conditions and electrical performance), large equipment and high-load buttons are directly replaced by conductive rubber or dome switch hardware shrapnel, such as medical equipment, TV. machine remote control, etc.
