What is a rheostat? A rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption. The construction is very similar to the construction of a potentiometers. It uses only two connections, even when 3 terminals (as in a potentiometer) are present. The...

A rotary switch operates with a twisting motion of the operating handle with at least two positions. One or more positions of the switch may be momentary (biased with a spring), requiring the operator to hold the switch in the position. Other positions may have a detent to hold the position when released. A rotary switch may have multiple levels or "decks...

LGSWITCH Rocker switches provide a visually pleasing way to switch on and off your electrical circuits. Most rocker switches are designed to fit a rectangular cutout, which is much harder to achieve than simply drilling a hole. Because of how nice they look, the extra work involved can be worth it. Rocker switches come in either two function, such ...

What is a Potentiometer? A potentiometer is also commonly known as a potmeter or pot. The most common form of potmeter is the single turn rotary potmeter. This type of pot is often used in audio volume control (logarithmic taper) as well as many other applications. Different materials are used to construct potentiometers, including carbon composition, cerme...

It has been many years that North America and Europe each have their own switch testing standard. It is UL1054 in USA and EN61058 in Europe. UL decide to harmonize their standard to the Europe’s by introducing a new standard, UL 61058-1. The purpose may be that that once the applicant passes the new standard’s testing, the applicant can both have North A...
