接近开关是一种无需与运动部件进行机械直接接触而可以操作的位置开关，当物体接近开关的感应面到动作距离时，不需要机械接触及施加任何压力即可使开关动作，从而驱动直流电器或给计算机(plc)装置提供控制指令。接近开关是种开关型传感器(即无触点开关)，它既有行程开关、微动开关的特性，同时具有传感性能，且动作可靠，性能稳定，频率响应快，应用寿命长，抗干扰能力强等、并具有防水、防震、耐腐蚀等特点。产品有电感式、电容式、霍尔式、交、直流型。

Proximity switch, also known as non-contact switch, is an ideal electronic switch sensor. When the metal detector is close to the switch, the switch can be no contact, no pressure, no spark, rapid electrical instruction, accurate reaction out of the POSTTTION of the movement mechanism, even for general stroke control, its POSTTTIONing accuracy, operating frequency, service life, installation and adjustment of the convenience and the applicability of the harsh environment, is a general mechanical type travel switch can not be compared. It is widely used in machine tools, metallurgy, chemical industry, textile and printing industry. In the automatic control system can be used as the limit, counting, POSTTTIONing control and automatic protection link, etc..

按钮开关(英文名称：push-button switch)是指利用按钮推动传动机构，使动触点与静触点按通或断开并实现电路换接的开关。按钮开关是一种结构简单，应用十分广泛的主令电器。在电气自动控制电路中，用于手动发出控制信号以控制接触器、继电器、电磁起动器等。

Many kinds of button switch structure, can be divided into ordinary button type, mushroom head,

Self lock, self reset type, rotary type, with indicator light type, with lamp symbol type and key type, [1] have single button, double button, three button and different combination form, general is a building block type structure, by the button cap, reset spring, bridge contact and shell, usually made of composite, have a pair of normally closed contacts and often open contacts, some products can increase the number of contacts by the number of contacts. There is a self-contained button, you can keep the closed POSTTTION automatic press, after the power to open.

Button switch can be completed to start, stop, positive reverse, variable speed and mutual lock and other basic control. Usually each button switch has two pairs of contacts. Each pair of contacts is made from an open contact and a normally closed contact. When press the button, the two pairs of contacts are the same time, the normally closed contact is disconnected, and the open contact is closed.

In order to indicate the role of the various buttons, to avoid false operation, usually the button cap made of different colors, to show the difference, its color is red, green, black, yellow, blue, white, etc.. For example, red means stop button, green indicates the start button, etc.. The main parameters, type, installation hole size, contact number and current capacity of the switch are described in detail.
