Electric switch with dynamic brake contact shared for making and breaking a power circuit

摘要

A double pole single throw electric switch has normally closed contacts of one pole connected in a dynamic braking circuit with a motor load and normally open contacts connecting the motor to a source of power. A partial movable contact conductively connected to movable contacts of the normally open contacts is disposed in normally open position relative to one contact of the normally closed contacts to provide a parallel path through the switch for making and breaking the circuit to the power source.
