电感式接近开关属于一种有开关量输出的位置传感器，它由LC高频振荡器和放大处理电路组成，利用金属物体在接近这个能产生电磁场的振荡感应头时，使物体内部产生涡流。这个涡流反作用于接近开关，使接近开关振荡能力衰减，内部电路的参数发生变化，由此识别出有无金属物体接近，进而控制开关的通或断。这种接近开关所能检测的物体必须是金属物体。
电容式接近开关亦属于一种具有开关量输出的位置传感器，它的测量头通常是构成电容器的一个极板，而另一个极板是物体的本身，当物体移向接近开关时，物体和接近开关的介电常数发生变化，使得和测量头相连的电路状态也随之发生变化，由此便可控制开关的接通和关断。这种接近开关的检测物体，并不限于金属导体，也可以是绝缘的液体或粉状物体,在检测较低介电常数ε的物体时，可以顺时针调节多圈电位器（位于开关后部）来增加感应灵敏度，一般调节电位器使电容式的接近开关在0.7-0.8Sn的位置动作。
由此可见，霍尔效应的灵敏度高低与外加磁场的磁感应强度成正比的关系。我门销售的霍尔开关就属于这种有源磁电转换器件，它是在霍尔效应原理的基础上，利用集成封装和组装工艺制作而成，它可方便的把磁输入信号转换成实际应用中的电信号，同时又具备工业场合实际应用易操作和可靠性的要求。
霍尔开关的输入端是以磁感应强度B来表征的，当B值达到一定的程度（如B1）时，霍尔开关内部的触发器翻转，霍尔开关的输出电平状态也随之翻转。输出端一般采用晶体管输出，和接近开关类似有NPN、PNP、常开型、常闭型、锁存型（双极性）、双信号输出之分。
霍尔开关具有无触电、低功耗、长使用寿命、响应频率高等特点，内部采用环氧树脂封灌成一体化，所以能在各类恶劣环境下可靠的工作。霍尔开关可应用于接近开关，压力开关，里程表等，作为一种新型的电器配件。
