Detail of fuel pump face plate showing over-speed switch and mounting. The switch plunger (part with disc shaped hand knob on left) is shown in the out or armed position. The RPM of the tubo-pump (TP) was not governed but this safety mechanism shut the TP down permanently when the RPM reached 5000. Although rarely changed, thin shims could be used to reduce or increase this speed. 3D model Ray Matter
