Standex Electronics has created a series of mini magnetic field sensing reed switches, optimised to control up to 10W, 200V or 500mA. Called MK33, they are bare glass surface-mount reed switches with ...

The Series J255 magnetic-latching, half-size crystal can relay has been designed for military, aerospace and space applications. The dual-pole, dual-throw relay switches up to 2A at 28 Vdc and is ...

The essence of the circuit is for the input of tone and signal to provide an activation for the relay switch. Relay – an electrically operated switch where the current flowing through the coil of the ...

The reed relay was invented in 1936 by Bell Telephone Laboratories. Since that time, it has gradually evolved from very large, relatively crude parts to the small, ultra-reliable parts we have today.
