As can be seen, has a set of heavy contacts, there is a heating element which would cause the bi metal contacts to bend and make contact. No idea what this would have been used for, it is old probably 1940s. Any info would be welcome thanks.

Looks like a starter for fluorescent lamps.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

Found out more. Made by philips No 4152 use: mercury vapour rectifier time to reach working temps before anode volts were applied, premature application of anode volts would lead to early failure of the rectifier. Check out National Valve Museum.

Interested in the history of electric lighting and incandescent in particular and neon glow lamps.
