9. A latch, comprising:
-
a fork bolt that moves between an unlatched position and a latched position; a first detent lever that that cooperates with the fork bolt and moves between an engaged position and a disengaged position, wherein the first detent lever prevents the fork bolt from moving from the latched position to the unlatched position when the first detent lever is in the engaged position; a hold open lever configured for movement between a blocking position and an unblocking position, wherein the hold open lever maintains the first detent lever in the disengaged position when the hold open lever is in the blocking position and wherein the hold open lever is configured to allow the first detent lever to move into the engaged position when the hold open lever is in the unblocking position and wherein the hold open lever is configured to allow a feature of the fork bolt to pass through the hold open lever as the fork bolt moves from the latched position to the unlatched position and wherein the feature of the fork bolt contacts and moves the hold lever from the blocking position to the unblocking position as the fork bolt moves from the unlatched position to the latched position; and a single switch that is only activated by movement of the hold open lever. - View Dependent Claims (10, 11, 14, 15, 16, 17)

18. A method of determining a state of a latch, comprising:
-
movably mounting a fork bolt to the latch for movement between an unlatched position and a latched position; movably mounting a first detent lever to the latch for movement between an engaged position and a disengaged position, wherein the first detent lever prevents the fork bolt from moving from the latched position to the unlatched position when the first detent lever is in the engaged position; movably mounting a hold open lever to the latch for movement between a blocking position and an unblocking position, wherein the hold open lever maintains the first detent lever in the disengaged position when the hold open lever is in the blocking position and wherein the hold open lever is configured to allow the first detent lever to move into the engaged position when the hold open lever is in the unblocking position and wherein the hold open lever is configured to allow a feature of the fork bolt to pass through the hold open lever as the fork bolt moves from the latched position to the unlatched position and wherein the feature of the fork bolt contacts and moves the hold lever from the blocking position to the unblocking position as the fork bolt moves from the unlatched position to the latched position; and actuating only a single switch via movement of the hold open lever. - View Dependent Claims (19, 20)
