ABSTRACT:
A pitot tube assembly for actuating a marine speedometer including an elongated blade member with the pitot tube passage therein and rotatably supported by an integral plastic bracket. The plastic bracket has two spaced support arms with a pin extending therebetween for rotatably supporting the blade member. A pair of spaced slots extend through the bracket between the two support arms to define an integral resilient spring section which is engaged by a cam surface on the blade member. The cam surface on the blade member includes a first flat portion which engages the resilient section to maintain the blade member in the down position and a second portion extending from an apex at the juncture with the first flat portion at an angle so that, when the apex engages the resilient section and passes over center, the second flat portion would engage the resilient section to maintain the blade member in the raised position.
