Magnetic Reed Switch Symbol

The basis of any reed relay is the reed switch itself this is the core element of the reed relay.

Magnetic reed switch symbol.

Options for customization such as lead cutting and forming are available. The basic reed switch is a single pole single throw normally open switch also known as a spst no or form a switch. The contacts are usually normally open closing when a magnetic field is present or they may be. The transducers sensors and electrical and electronic detectors are elements activated by the energy delivered by a system and that in turn deliver another type of energy to another different system the transformed energy may be of physical chemical or biological origin.

Currently only available as pdf catalogue. The relay are switching devices activated by signals. Relay symbols and electromagnets. In the lift switchgear section you will find lift switchgear for various applications in the shaft pit the lift car and the machine room.

Symbols of electronic sensors transducers detectors. By adding an additional nonmagnetic contact that is electrically closed with no magnetic field present a single pole double throw switch can be made. Standard electrical iec symbols also known as iec 60617 british standard bs 3939 used to represent various devices including pilot lights relays timers and switches for usage in electrical schematic diagrams. The reed switch contacts overlap so that when they close they make contact with each other.

Littelfuse offers the widest selection of magnetically operated reed switches. Floor and fine adjustment switches positive break door contacts position switches magnetic reed switches remote alarm systems as well as the usp ultrasonic elevator positioning system. Reed switches are available in bare glass or overmolded packages with a variety of mechanical electrical and magnetic characteristics. Actuating surface and direction of actuation marked by switch symbol.

A reed switch consists two reed contacts typically made from nickel iron and then plated with materials to ensure the maximum life to the device. In its simplest and most common form it consists of a pair of ferromagnetic flexible metal contacts in a hermetically sealed glass envelope. 85 mm x 26 mm x 24 mm. Most of the time a small voltage or current is used to switch other voltages or higher currents that may be electromechanical or fully electronic type.
