ABSTRACT:
In an acceleration switch, such as used for actuating an impact detonator in a projectile, a ball is held between a support surface and a lever member which forms a part of a toggle lever assembly. On impact, the ball causes the lever to pivot and displace another lever member to which it is pivotally connected. When displaced, the toggle lever assembly passes through a dead center position and a portion of its another lever is moved out of the path of a light source and light detector for closing the ignition circuit of the impact detonator. A releasable safety device is provided to prevent premature movement of the lever assembly which would close the ignition circuit.
