Abstract
A 'center-off' rocker/actuator switch has cooperating contact lever and actuator pin surfaces that obviate the need for a yoke on the center fixed contact to support the contact lever in its center position. The pin has an enlarged head at its inner end to engage the lever at one or two spaced locations to so support the lever in its center position. A momentary 'on' versions has steeply inclined regions of the contact lever on at least one side of the center pivot area thereof, and two progressive 'on' versions are disclosed, one with upturned marginal edge portions on the contact lever that cooperate with the pins unique head configuration to permit holding the contact lever 'on' in the neutral or 'center-off' position for the actuator. The second progressive 'on' switch has two 'center-off' type contact levers and uniquely shaped pins designed to hold these contact levers in oppositely oriented limit positions when the actuator is centered.
