Double Break:

by | Mar 14, 2021

A contact mechanism using two sets of contacts to make or break a given circuit. The contact gap opens twice as fast, reducing the arc duration, contact surface temperature and material erosion. This improves heat dissipation and provides better power handling...

Double Throw:

by | Mar 14, 2021

Contact arrangement that allows current to flow from the common terminal to a normally closed terminal and then to a normally open terminal. Please refer to the ITW Switches Characteristics/Circuits for more detail.

Current-Carrying Capacity:

by | Mar 14, 2021

Specified maximum current which can flow through the switch contacts. Determined by contacts size, shape, material and the force with which they are pressed together.

DPDT (Double Pole Double Throw) Switch Configuration:

by | Mar 14, 2021

Double pole means two independent circuits are actuated by the button. Double throw means the common terminal of each circuit (pole) can transfer current to a normally closed terminal and then alternately to a normally open terminal.
