Miniature MEMS-based electro-mechanical safety and arming device

A safety and arming device, comprising:

• a substrate;
• a frame disposed on the substrate;
• a setback slider disposed in the frame, the setback slider moving linearly in response to a setback acceleration;
• the setback slider including, on an end of the setback slider in a direction of the setback acceleration, a setback slider spring attached at one end to the setback slider and at another end to a setback slider latch head, the setback slider latch head for prebiasing the setback slider spring by inserting the setback slider latch head in a setback slider spring head socket in the frame;
• the setback slider further including, on an end of the setback slider in a direction opposite to the direction of the setback acceleration, a second setback slider latch head for locking the setback slider after its linear movement by inserting the second setback slider latch head in a setback slider latch socket in the frame;
• an arming slider disposed in the frame, the arming slider moving linearly in an arming direction perpendicular to the direction of the setback acceleration and in response to spin;
• the arming slider including, on an end of the arming slider in a direction opposite the arming direction, an arming slider spring attached at one end to the arming slider and at another end to an arming slider latch head for prebiasing the arming slider spring by inserting the arming slider latch head in an arming slider spring head socket in the frame;
• a setback lock lever disposed in the frame, the setback lock lever engaging the arming slider to prevent linear motion of the arming slider until the setback slider contacts and moves the setback lock lever;
• and
• a command lock rocker disposed in the frame, the command lock rocker engaging the arming slider to prevent full arming motion of the arming slider until after the command lock rocker is actuated.
