<p>An over-center toggle latch for securing two members together having a latch housing affixed to one of the members, a keeper affixed to the other of the members, a toggle pivotally mounted within the housing for pivotal movement between a first position and a second position, and a retainer disposed within the housing and in pivotal contact with each of the housing and the toggle for retaining the toggle in either of the first and second positions. The keeper pivots the toggle from the first position to the second position upon the closing of the latch and the keeper pivots the toggle from the second position to the first position upon the opening of the latch. A switch operable between a closed position and an open position wherein a circuit is closed only when the keeper means is in the second position and the circuit is open only when the keeper is in the first position, the switch being completely inoperable until the keeper is fully inserted in the housing whereby closing of the circuit is avoided.</p> |
