What will happen to the switch after 60 years. I decided to test

I was in the stairwell of Khrushchev set abandoned long idle switch. Sometimes, for the sake of interest, he switched his arm, it worked with a visible effort and sonorous click.

I lived there for many years and I was wondering how much his age and whether it is working. I have LED multi-function screwdriverWhich is a non-contact manner can determine the presence of phase her, I once again convinced that the phase does not go to him.

Unscrew a rarity, and the wires from old habit insulated and installed the plug, and the ugly.

Disassembly and inspection

He brought into the apartment, disassembled, laundered and cleansed from dirt, debris and dust. The mechanism was completely collapsible and durable with no visible signs of wear and the spring does not lose its properties.

The fact that it can be disassembled to screw, guaranteeing the possibility of replacing any parts when repairing. Everything was so simple and safe that it can be broken only by hitting it with a hammer or drop from a height on concrete or tile, housing karbolit brittle material.

Made the switch was in August 1959 and was worth 34 kopecks, which means that he was 60 yearsAs Khrushchev, in which I live.

inspection

I connect the tester, for clarity, and five times switched the instrument to react normally, fixing the circuit and open circuit.

Designed in the rare book, certainly not modern, but I thought, how many years can expect to live a modern, trendy switch without losing the look or functionality? Hardly 60 years stretch, but you think?

People, refinement, this switch, not yet 60 years old, he made no earlier than 1961 (the year of the currency reform), that does not detract from all of the above. Drew attention to this in the comment Olga, for which she thanks!
