Abstract
A ground start key switch for use with a modular duplex adapter to permit momentarily shorting a pair of jack terminals includes a switch actuator mechanism adapted to be mounted onto the modular duplex adapter having a pair of jack terminals and a conductor member attached to the switch actuator mechanism. The switch actuator mechanism includes a resilient lever arm which is depressible for causing engagement of the conductor member with the pair of jack terminals so as to electrically short the pair of jack terminals together. When the resilient lever arm is released, the resiliency thereof returns the conductor member thereof to its normal position at which the conductor member is disengaged from the pair of jack terminals such that the latter are not longer shorted together.
