black porcelain switch - double nickel-plated push-button

A push-button is not a normal switch. The electric current is only transmitted when the button is pressed (for example a doorbell). 
But if a push-button is used in combination with an impulse relay in the fuse box, then it can be used as a one-way switch, a two-way switch, a timer or a stairwell switch. 
And if a push-button is used in combination with home automation then it can be used as a one-way switch, a two-way switch or a stairwell switch, a dimmer, a shutter switch, a doorbell button, a master switch, etc. 

General characteristics push-button: 

- Compatible with Ø 7 cm flush-mounted boxes. 
- Compatible with stairwell impulse relays. 
- Compatible with home automation. 
- Compatible with a timer.

Soon after being established in 2009, zangra started to successfully cooperate with different porcelain factories all over the world – a cooperation that continues to this day. In recent years, zangra has spent a lot of time in world’s most famous porcelain cities. From Limoges in France to Jingdezhen in China, zangra was able to work at legendary porcelain factories. So in cooperation with the staff zangra created new models and rediscovered old forgotten molds. A number of old molds were put back in production making new pieces. zangra’s porcelain is still produced by hand, piece by piece. This makes each piece unique. zangra's work proved successful with their products being sold all over the world.
