Abstract
A switching mechanism has first and second contacts, an elastic member, and a stopper. The first and second contacts are electrically connectable with each other. The operation of the first circuit is switched by electrically connecting the first and second contacts. The stopper maintains the elastic member in an elastically deformed state. At least a part of the stopper is capable of disintegrating by contact with a predetermined liquid. The elastic member recovers from deformation as at least of a part of the stopper disintegrates, and thereby displaces the second contact such that the second contact gets electrically connected to or disconnected from the first contact.
Claims19
A switching mechanism for a swallowable medical device, said device comprising a shell and a first circuit unit provided in the interior of said shell, said switching mechanism comprising:
- first and second contacts that are electrically connectable with each other and provided in said interior, said first circuit unit being operated when said first and second contacts are electrically connected;
- an elastic member;
- and
- a stopper that maintains said elastic member in an elastically deformed state, at least a part of said stopper capable of disintegrating by contact with a predetermined liquid,
- said elastic member recovering from deformation as at least a part of said stopper disintegrates, thereby displacing said second contact such that said second contact gets electrically connected to or disconnected from said first contact.
