If the 'Full Frame' body was using a 24-70/2.8 lens and the 'APS-C' body was using a 16-50/2.8 lens, they would both be capable of almost identical images, but with an aperture of f/2.8 and a subject distance of 7 feet, the 'Full Frame' body would have a DoF of 0.5 feet and the 'APS-C' body would have a DoF of 0.66 feet, about what the 'Full Frame' ...
A Double Pole Double Throw (DPDT) switch is a switch that has 2 inputs and 4 outputs; each input has 2 corresponding outputs that it can connect to. Each of the terminals of a double pole double switch can either be in 1 of 2 positions. This makes the the double pole double switch a very versatile switch. With 2 inputs, it can connect to 4 different outputs or reroute a circuit into 4 different modes of operation. A Double Pole Single Switch is actually two single pole double (SPDT) switches.
The normally closed, typically denoted as NC, is closed when the switch is unactuated (power may flow through this contact when the switch is in its unactuated state). When the force actuates the switch, contact closure reverses (power may flow through the NC switch and may NOT flow through the NO switch).eport Abuse. SPDT means single pole, double throw. This means there is a centre contact, and one on either side, In one position the switch connects the centre connection to one of the side terminal, and in the other position, well ... the other terminal.
