Dallas—Texas Instruments Inc. has introduced power distribution switches with an integrated FET that can be set to support a 100-mA to 1.1-A current limit range for a standard USB port or other ...

Limit switches: A mechanical limit switch interlocks a mechanical motion or position with an electrical circuit. A good starting point for limit-switch selection is contact arrangement. The most ...

Mechanical position and electrical circuitry meet in the no-nonsense limit switch. These cost-effective input devices excel in tough environments and are as simple to install as they are to maintain.

We’re used to thinking of limit switches as a mechanical device that cuts the motor connection before physical damage can occur. [Anthony] decided to try a different route with this project. He built ...

Placing a switch and a fuse between a power supply and its load allows for control and protection of power. An improvement on a simple switch and fuse is an integrated circuit that accomplishes the ...
