Electromechanical switch having a movable contact and stationary contacts

A power circuit comprising:

• an electromagnetic driving unit;
• a switch operably coupled to the electromagnetic driving unit;
• and
• an electromechanical switch comprising first and second stationary contacts and a movable contact, each of the first and second stationary contacts having a respective mating end, the movable contact having first and second contact zones, the first and second contact zones being separate regions of the movable contact that are operable to be covered by the respective mating ends of the first and second stationary contacts, respectively, the movable contact including opposite mating and mounting sides and also including first and second contact ends in which each of the mating and mounting sides extends between the first and second contact ends, the mating side including the first and second contact zones;
• wherein each of the first and second contact zones has a corresponding mating surface and a corresponding recess that divides at least a portion of the corresponding mating surface, wherein each of the respective mating ends is configured to extend across the corresponding recess and engage the corresponding mating surface on opposite sides of the corresponding recess, the corresponding recess having a depth that extends only partially into the movable contact;
• and
• wherein the switch is operably coupled to the movable contact, the electromagnetic driving unit operable to move the switch between at least two different positions to connect and disconnect a power supply.
