CONT

Any device which, when actuated opens or closes a set of electrical or mechanical contacts, such as a door switch or relay.

CONT

Door contacts. Magnetic door contact switches can be concealed or surface mounted.... These are electromechanical sensors that are composed of two electrical contacts.... When the door is closed the two contacts are in the open position. When the door opens, the wall portion(magnet) is moved away from the switch, allowing the contact to close, thereby causing a disruption in current flow and the alarm signal is generated.

Record 6 1998-01-19

English

Subject field(s)
  • Plastics Manufacturing
CONT

Reciprocating screw systems. In a reciprocating(in-line) screw, the material is fed from the hopper, plasticized in the screw, and forced past a one-way valve at the injection end of the screw. The material accumulates in front of the screw, forcing back the screw, its drive and motor, and the pistons of the two hydraulic injection cylinders.... When the screw reaches a certain position, it contacts a limit switch that stops the rotation. When the cycle is ready to inject, two hydraulic injection cylinders, one on each side of the carriage, move the screw assembly forward and use the screw as an injection ram.

Key term(s)
  • in-line screw system
