Switches that will only complete one circuit at a time, leaving an interval of time between the time one circuit opens and the next circuit closes.

Sparking that occurs each time a switch is turned on or off, except in very low voltage and low current applications. This sparking can burn up the switch contacts and reduce the life of a switch. In [..]

The tendency for butt action contacts to bounce apart as they come together. The bouncing action can prolong and arc, or open and close the circuit very quickly several times before coming to a closed [..]

The maximum current in amperes, at rated current and frequency, that a device will carry continuously under defined conditions without exceeding specified performance limits.

An actuator is the mechanical component used to manually turn a switch or circuit breaker on and off.

Term applied to an electric current or voltage that reverses its direction of flow at regular intervals and has alternately positive and negative values, the average value of which over a period of ti [..]
