A safety interlock keeps the door closed when the switch is on and prevents the switch from turning on when the door is open.
Double throw safety switch diagram.
Also known as safety switches they have spring driven quick make quick break action to eliminate arcing and prolong switch life.

Each of the terminals of a double pole double switch can either be in 1 of 2 positions.
Shunt trip for safety switches.
When the switch is in one position the common terminal is connected to the a terminal so current flows from the common terminal to the a terminal but no.
Double throw switches are intended to transfer loads from one power source to another.
Eaton shunt trip safety switches provide remote switching visible means of disconnect for commercial.
The interlock ensures both switches cannot be closed at the same time preventing them from being operated in parallel.

This makes the the double pole double switch a very versatile switch.
One of the terminals is called the common terminal.
The heavy duty quick connect single throw design is typically used with your main utility when temporary power is required such is to connect a sound or lighting system media equipment carnival equipment.
Single pole throw and double pole throw switches are by far the most common switches but triple and quadruple configurations are also available.
A double throw switch connects an input terminal to one of two output terminals.
The motor s two power leads are reversed at one of the switches screw terminals.
A double pole double throw dpdt switch is a three selection electrical device in which there is one off and two on positions.
A double pole double throw dpdt switch is a switch that has 2 inputs and 4 outputs.
All are ul listed.
An application for this switch is for reversing a direct current dc electrical motor.
Switches are rated for use on systems up to 10 000a when protected with class h fuses or up to 200 000a when protected with class r j or class t fuses.
Protected by a steel enclosure these switches withstand tougher conditions than switches in a plastic housing.
A dt switch can also have a center position frequently on off on.
All 2 and 3 pole double throw switches are suitable for use as service equipment.
Thus a double pole switch has three terminals.
Each input has 2 corresponding outputs that it can connect to.
Dt switches close a circuit in the up position as well as the down position on on.
