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 ...

Limit switches: A mechanical limit switch interlocks a mechanical motion or position with an electrical circuit. Limit switches: A mechanical limit switch interlocks a mechanical motion or position ...

New five-way adjustable limit-switch-style sensors, for 10 to 30-Vdc operation, have an active sensing face that can be adjusted for front, top, bottom, left, or right-facing targets. Four-corner LEDs ...

You use limit switches to switch off a motor if it reaches one of its two end positions. Even if you build a microprocessor-based motor controller, you should switch off a motor with hardware by ...

There are a bunch of low cost cnc engraving machines loosely called ‘3018’ as they cut material up to 30 x 18cm, and the same parts are used in two smaller sizes down to a 1610. They are not the ...

A flap controller needs current limiting to protect the motor when the flap reaches full closure. A small incandescent lamp can perform this task without the need for more costly limit switches or a ...

The ability to turn on loads in a controlled manner is important in applications where the power budget is limited. Hard switching a load can cause the input power rail to droop and result in a fault.

3D Printer tool changers are bedazzling to watch, but even failed attempts at tool changers can yield something marvelous. Such is the case for [Raymond] who transformed a tool changer attempt into a ...

A range of mechanical limit switches are constructed of durable thermoplastic or rugged zinc alloy metal, capable of withstanding the most demanding of installation environments, says the vendor. The ...
