When the relay is triggered ... kΩ is a good starting point for replacing pushbuttons. A simple test circuit (using a switch to provide the current needed instead of a microcontroller) may ...

Manufacturers of switches and relays focus on miniaturization while delivering greater functionality with more options.

Single pole means that it can only control a single circuit, and single throw means that there are only two positions the switch can be in (one on, and one off state). Mechanical relays do not ...

Socket relays are mounted to PCBs using pin sockets. The term "pole" describes the number of separate circuits controlled by a switch. The number of circuits controlled by the relay determines the ...

An optically isolated relay does not have a direct electrical contact between the input (control) and output (switching) circuits, whereas a non-isolated devices does have this connection. Relays may ...

Standard relays and safety relays are two distinct types of devices, each designed for different purposes and serving ...

Unlike circuit switching in traditional telephone networks ... Subsequent packet technologies, such as frame relay, were designed for almost-error-free digital lines. THIS DEFINITION IS FOR ...

A high-speed packet switching protocol used in wide ... via point-to-point lines or an ATM backbone. Frame relay provides Permanent Virtual Circuits (PVCs) and Switched Virtual Circuits (SVCs).

By looking at a circuit diagram of a transistor switching circuit, you should be able to say what the circuit is used for and be able to explain how it operates. This transistor switching circuit ...
