Special type of relay consisting of five moving, reed-like contacts controlled by an electromagnet where the reeds themselves are part of the magnetic as well as the electrical circuit being controlled.
A reed switch is a passive device consisting of two reed contacts sealed inside a glass tube which operates when brought near a magnetic field.
an electric switch A switch is a device for making or breaking an electric circuit, or for selecting between multiple circuits
a switch which is operated by a magnetic field
A magnetically operated switch usually mounted on doors, but may be mounted on windows, designed to detect their movement. Upon movement detection sends a signal to the control box which then sounds the siren.
This is a miniature mechanical switch which changes state when a magnetic field is applied.
A type of switch within the pulse generator. The reed switch closes when a magnet is placed over it, forcing the pulse generator to pace asynchronously. The removal of the magnet opens the reed switch and restores sensing and pacing at the programmed parameters.
A serviceable, magnetic sensing switch that triggers the water flow to stop when the neck jet pillow (with magnet) is removed from the whirlpool
The reed switch is an electrical switch operated by an applied magnetic field. It was invented at Bell Telephone Laboratories in 1936 by W. B. Elwood.
