English term or phrase: contact closure
W tym kontekście:

In control systems, relays and contact closures can be very effective means of control. A device that can be controlled using contact closures, such as an Extron SW 2 VGA DA2 A, will be wired to a control processor's relays. The low voltage relays on the control processor creates the contact closure.

Explanation:
Digital Inputs

Many types of digital input signals from switch closures, relay contacts, or TTL-compatible interfaces can be read directly by digital I/O cards (Figure 2-1). Other types of inputs may require some signal conditioning, most likely to reduce higher-level voltage changes to TTL levels. A variety of signal conditioning modules are available to provide isolation and other digital conditioning functions.

The most common type of digital input is the contact closure. Essentially a sensor or switch of some type closes or opens a set of contacts in accordance with some process change. An applied electrical signal then determines whether the circuit is open or closed. Current flows if the circuit is closed, registering a "1" in a transistor at the computer interface. Conversely, an open circuit retains a high voltage (and no current), registering a "0" at the transistor.
