Proximity switch definition

WebbReed switches actuated by magnets are commonly used in mechanical systems as proximity sensors. Examples are door and window sensors in burglar alarm systems and tamperproofing methods. Reed switches have been used in laptops to put the laptop into sleep/hibernation mode when the lid is closed.

WebbPole refers to the number of circuits controlled by the switch: SP switches control only one electrical circuit. DP switches control two independent circuits (and act like two identical switches that are mechanically linked). Do not confuse ‘pole’ with ‘terminal’. The DPST switch, for example, has four terminals, but it is a DP, not a ... WebbProximity Switches A proximity switch is one detecting the proximity or closeness of an object. These switches are non-contact sensors, using magnetic, electric, or optical means to sense the proximity of objects. Most proximity switches are active in design. That is, they incorporate a powered electronic circuit to sense the proximity of an ... incontinence products wholesale suppliers https://tammymenton.com
