fixed contact

Fixed contacts may be backed up with a spring.

Fixed contacts are inexpensive but prone to loss of electrical connection.

If the bell or chime sounds continuously, the fixed contact is bent too far.

The majority of the wire spring relays manufactured in the 1960s had twelve fixed contacts.

When the switch was idle, the wipers were disengaged from the fixed contacts.

Each fixed contact, in the shape of a square box, is mounted on the end of a thick wire stem.

A "make" contact, a "break" contact, or both can be provided for each fixed contact.

The moving contacts are held away from the fixed contacts by a phenolic paper pattern called a "card".

Teaching unions will hope that she will set a fixed contact time for teachers with pupils to try to answer their concerns about excessive workloads.

Three sets of fixed contacts were permanently wired together and to the 26 way input and output connectors.

Battery contacts may be fixed contacts, flexible contacts, or some combination of the two.

Knife switches consist of a flat metal blade, hinged at one end, with an insulating handle for operation, and a fixed contact.

When the switch is closed, current flows through the hinged pivot and blade and through the fixed contact.

Each contact is either a fixed contact, which does not move, or is a moving contact, and is made from a short piece of wire.

The moving contact is propelled by the moving core; the force developed by the electromagnet holds the moving and fixed contacts together.

Power supply studs are the fixed contact elements of a stud/skate or stud/ski collector electrical connection system.

Clean between the contacts with fine-grit sandpaper until the metal shines; then pry up the fixed contact, not the one that moves, slightly with a screwdriver.

Smartcard The DD55SC and DD35SC units feature a low power smartcard reader with fixed contacts.

Early examples of a rheostat dimmer include a salt water dimmer or liquid rheostat; the liquid between a movable and fixed contact provided a variable resistance.

Rough adjustments can be made to the fixed contacts as a whole by inserting a screwdriver blade into a slot in the front support structure and twisting as appropriate.

With fixed contacts relying on bolted joints or pinch screws bearing on a conductor in a tunnel, the dissimilar metal effects can be greater than with other types of contacts.

It consists of a set of contacts mounted on the machine's shaft, combined with graphite-block stationary contacts, called "brushes", because the earliest such fixed contacts were metal brushes.

In an overcurrent condition, a value of current will be reached that overcomes the control spring pressure on the spindle and the braking magnet, causing the metal disc to rotate towards the fixed contact.

In most applications, such as telephony, it is desirable to be able to return the wipers to a "home" position; this is at the beginning of rotation, at one end of the array of fixed contacts.
