Interlock door switch

A switch for switching between two electrical circuits, the switch comprising:

• a first contact;
• a first conductor engageable to and disengageable from the first contact for respectively electrically closing and electrically opening a first electrical circuit electrically associable therewith;
• a second contact;
• a second conductor engageable to and disengageable from the second contact for respectively electrically closing and electrically opening a second electrical circuit electrically associable therewith, the first conductor being substantially electrically isolated from the second conductor;
• and
• an actuator adapted for receiving the first conductor and the second conductor and whereto each of the first conductor and the second conductor is movably coupled, the actuator is positionable to a first position for engaging the first conductor to the first contact and disengaging the second conductor from the second contact and positionable to a second position for disengaging the first conductor from the first contact and engaging the second conductor to the second contact,
• wherein the actuator is shaped and dimensioned and is configured with each of the first conductor and the second conductor for substantially impeding engagement of the first conductor with the first contact when the second conductor is engaged to the second contact and for substantially impeding engagement of the second conductor with the second contact when the first conductor is engaged to the first contact,
• whereby simultaneous electrical closing of the first electrical circuit and electrical closing of the second electrical circuit is substantially prevented.
