Abstract
A switch may comprise a metal plate. A eutectic alloy may be proximate to the metal plate. An insulating material may be proximate to the insulating material. The insulating material may include a recess in the insulating material adjacent the eutectic alloy. A lead may be fixed in place by the insulating material. A first end of the lead is exposed from the insulating material by the recess.
Claims15
A switch, comprising:
- a metal plate;
- an eutectic alloy proximate to the metal plate;
- an insulating material proximate to the eutectic alloy and including a recess in the insulating material adjacent the eutectic alloy;
- and
- a lead fixed in place by the insulating material, wherein a first end of the lead is in the recess and electronically isolated from the eutectic alloy prior to a detonation;
- and wherein after the detonation
- the recess is no longer provided and the eutectic alloy contacts the lead.

A pyrotechnic switching system, comprising:
- a detonation transfer assembly including an explosive output configured to create an air signal;
- a pyrotechnically actuated switch coupled to the explosive output of the detonation transfer assembly, the pyrotechnically actuated switch comprising:
- a plate;
- an eutectic alloy adjacent the plate;
- and
- a lead adjacent the eutectic alloy with a recess completely separating the eutectic alloy and the lead before a detonation;
- and after the detonation,
- the plate melts the eutectic alloy and presses the eutectic alloy into the recess to contact the lead in response to the air signal.
