It consisted of a paper tube with metal fittings, a spring contact switch, bulb and brass reflector.
2.
Each track had its own stationary metal spring contact; one more contact made the connection to the pattern.
3.
The spring contacts in the connectors eventually relax and wear out with repeated cycles of plugging and unplugging.
4.
This corrugates the sides of the pockets to provide a spring contact of the pocket with the active material.
5.
In our spring contact [ with prospective students ), we said that the first 50 we heard from could be extras.
6.
A type much used in the past but mostly obsolete today has a spring contact that can slide along the bare surface of the windings.
7.
Deep-sea metallic mineral deposits in the seafloor hot springs contact cold sea water and precipitate out high-grade ore deposits containing gold, copper, lead, zinc, iron, manganese and other metals.
8.
In inexpensive sets, the inductor was made variable via a spring contact pressing against the windings that could slide along the coil, thereby introducing a larger or smaller number of turns of the coil into the circuit.
9.
Combination of fixed and flexible contacts are a better solution, but this is subject to an open circuit upon movement in the direction away from the fixed position; the spring contact compresses and allows the battery to move away from the fixed contact.
10.
If you are able to take your hi-fi apart ( having unplugged it first, of course ) to gain access to the socket, just gently clean the spring contacts with emery paper and very gently bend them in slightly towards the centre, but not too far or your headphone plug will not go in.
