When electricity came to the Swedish households in the early 1900s, it was initially a luxury product. If you could afford it, you would like to show it off with beautiful ornate switches. The round switches with cover were made in Germany, and the covers were usually made of porcelain but could also be found in bronze or brass. We can offer small round switches with toggle switch inspired by old-time brass switches. These are made of untreated brass and made by Fontini (see image 2 and below under related products). The untreated surface will be patinated over time and get a beautiful dark tone.

Image 1 shows a circular switch from Nyköping, early 1900s, which is molded in porcelain. The outside of the porcelain is black-painted and the cover is made of brass.

Figure 2 shows single-pole switches with cover and knobs of brass on porcelain base. These switches must have been manufactured before 1895 and belonged to the first electrical part at KTH's old building on Drottninggatan in Stockholm. On the same image a wooden base is also seen, which was a common material in the early days of electricity but which was soon banned because of fire hazard.
