surface mount black bakelite over-centre rotary two-way switch

This switch can be installed on a two-way or simple circuit.

What is a two-way switch?
Two-way switch, providing control of a light from two locations.
A two-way circuit is an electrical circuit that allows a lamp to be switched on or off from two switches, for example, a switch at each end of a corridor for the same lighting point.

What is a simple switch?
The simple switch, on the other hand, is used to switch a light on or off from a single location in the room (usually at the entrance to the room).

Functional and aesthetic, bakelite is the ideal material for electrical engineering.
Developed at the beginning of the 20th century by the Belgian chemist Leo Baekeland - from whom the term derives its name - bakelite is known for its heat-resistant properties, as well as its stability and high electrical insulation. Until the 1960s, bakelite participated in the elaboration and development of many technical innovations - such as the telephone and radio. For financial reasons, however, bakelite was gradually replaced by thermoplastic, which was less dense but also of a less comparable quality.
Today, in order to offer a quality alternative to thermoplastics, some factories located on the European continent are relaunching the production of bakelite, using traditional moulds and tools.
