Switch apparatus

A switch apparatus comprising:

• a printed substrate;
• a fixed contact defining a center and including at least a pair of first and second internal patterns and a pair of first and second external patterns;
• the internal patterns and the external patterns being formed on the printed substrate and separated from one another by a predetermined distance,
• the first internal pattern and the first external pattern defining a common pattern,
• the second internal pattern having at least a first segment pattern radially extending across the center in a first direction and a second segment pattern radially extending across the center in a second direction transverse to the first direction;
• and
• a movable contact that comes in contact with the fixed contact to perform a switching operation, the movable contact having a first movable contact and a second movable contact for contacting the pair of internal patterns and the pair of external patterns, respectively.

A switch apparatus comprising:

• a printed substrate;
• a fixed contact including a first pair of patterns and a second pair of patterns;
• the patterns of the first pair and the second pair being formed on the printed substrate and separated from one another by a predetermined distance;
• and
• a movable contact provided above and opposing the fixed contact, the movable contact for contacting the fixed contact to perform a switching operation, the movable contact having a first movable contact and a second movable contact for contacting the first pair of patterns and the second pair of patterns, respectively;
• wherein one of the first movable contact and the second movable contact initially comes into contact with one of the first pair of patterns and the second pair of patterns by depressing the movable contact, and the other of the first movable contact and the second movable contact then comes into contact with both of the first pair and the second pair by further depressing the movable contact.

A switch apparatus comprising:

• a printed substrate;
• a fixed contact formed on the printed substrate, the fixed contact including two rows of opposing comb-shaped fixed contact patterns interlaced with one another, the two rows of fixed contact patterns including a first fixed contact pattern, a second fixed contact pattern and a common pattern to be paired with the first fixed contact pattern and the second fixed contact pattern;
• and
• a movable contact disposed above the fixed contact, the movable contact including first and second movable contact patterns arranged in a predetermined orientation, the first and second movable contact patterns conductively connecting the common pattern paired with the first fixed contact pattern and the second fixed contact pattern, respectively.

A switch apparatus comprising:

• a printed substrate;
• a fixed contact formed on the printed substrate, the fixed contact including a first comb-shaped pattern having a first teeth-pattern section, a second comb-shaped pattern having a second teeth-pattern section opposing the first teeth-pattern section of the first comb-shaped pattern, and a common pattern disposed between the first comb-shaped pattern and the second comb-shaped pattern, the common pattern having a center segment pattern and teeth-pattern sections on both sides thereof interlacing with the first comb-shaped pattern and the second comb-shaped pattern, respectively;
• and
• a movable contact disposed above the fixed contact, the movable contact including a first movable contact pattern for conductively connecting the first comb-shaped pattern and the common pattern, and a second movable pattern for conductively connecting the second comb-shaped patter and the common pattern.
