Trendi Switch new Intermediate range!
Trendi Switch Intermediate update
Following on from our 1 gang gen 1 intermediate switch, Trendi Switch Ltd is pleased to announce the gen 2 intermediate is now available in not only 1 and 2 gang boxed product but also available in a modular 1, 2, 3 & 4 gang on single and double plates. See further information and images below, all modules can be moved around on the plate to create the complete light switch solution to your lighting project.
In a Trendi Switch intermediate switch, there are four terminals by which it changes the flowing of electric current from one circuit to another and also known as three way switch. It has the ability to ON and OFF the electric supply by two ways.
An Intermediate Switch can be used as a One Way or Two Way switch however is more expensive due to being a more complicated circuit, this means they are only used when necessary for circuits with three or more switches.
Three-way and four-way switches
A double pole, double throw switch wired to act as a four-way (intermediate or crossover) switch
Three-way and four-way switches make it possible to control a light from multiple locations, such as the top and bottom of a stairway, either end of a hallway, or multiple doorways into a large living room. These switches appear externally similar to single pole, single throw (SPST) switches, but have extra connections which allow a circuit to be controlled from multiple locations. Toggling the switch disconnects one “traveller” terminal and connects the other.
Electrically, a typical “3-way” switch is a single pole, double throw switch. By correctly connecting two of these switches together, toggling either switch changes the state of the load from off to on, or vice versa. The switches may be arranged so that they are in the same orientation for off, and contrasting orientations for on.
A “4-way” (intermediate) switch is a purpose built double pole, double throw switch, internally wired in manufacture to reverse the connections between the input and output and having only four external terminals. This switch has two pairs of “traveller” terminals that it connects either straight through, or crossed over (transposed, or swapped). An intermediate switch can, however, be implemented by adding appropriate external wiring to an ordinary (six terminal) DPDT switch, or by using a separate DPDT relay.
By connecting one or more 4-way (intermediate) switches in-line, with 3-way switches at either end, the load can be controlled from three or more locations. Toggling any switch changes the state of the load from off to on, or from on to off.
