\u0642\u0648\u0629 \u0627\u0644\u062a\u0634\u063a\u064a\u0644<\/strong>: The required force to change a circuit’s electrical state.<\/p>\n

Alternate (Latchin and Maintained) Action Switch<\/strong><\/a>: A Pushbutton style switch where the change of the electrical state is maintained between actuations.<\/p>\n

Ampere<\/strong>: A unit of electrical current flow.<\/p>\n

Base (Housing)<\/strong>: A base of a switch is the main member to which the conducting parts or insulator unit are attached. It may also have parts of the operating or control mechanism attached.<\/p>\n

Bounce<\/strong>: Rebounding of moving contact against fixed contact during transfer.<\/p>\n

Break<\/strong>: Interruption of a circuit. Double-break occurs when a single mechanism interrupts two contacts simultaneously.<\/p>\n

\u0627\u0644\u0633\u0639\u0629<\/strong>: Usually refers to the current handling capability of a switch.<\/p>\n

\u0627\u0644\u0627\u062a\u0635\u0627\u0644<\/strong>: The contact is a conducting part designed to be united by pressure to another conducting part for the purpose of carrying current.<\/p>\n

Operating Point<\/strong>: Point at which contacts transfer. Usually measured from the switch mounting holes.<\/p>\n

Over Travel<\/strong>: The distance an actuator travels after the circuit is closed.<\/p>\n

\u0627\u0644\u0639\u0645\u0648\u062f<\/strong>: The term to denote a completely separate circuit, which passes through a switch at one time.<\/p>\n
