Switch apparatus
First Claim
1. A switch apparatus comprising:
- a printed substrate;
a fixed contact generally defining a center and including a first pair of first and second fixed contact patterns and a second pair of first and second fixed contact patterns formed on the printed substrate, the fixed contact patterns of the first pair and the second pair being separated from one another by a predetermined distance, wherein the first fixed contact pattern of the first pair of fixed contact patterns and the first fixed contact pattern of the second pair of fixed contact patterns are the same and define a common pattern, the common pattern being disposed between the second fixed contact pattern of the first pair and the second fixed contact pattern of the second pair,the second fixed contact pattern of the first pair 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 engagement with the first pair of fixed contact patterns and the second pair of fixed contact patterns, respectively.

Abstract
A switch apparatus has a fixed contact including a contact pattern formed on a printed substrate and a movable contact provided above and opposing the fixed contact. A switching operation is performed by engaging the movable contact with the fixed contact. The fixed contact pattern has a first pair of fixed contacts and a second pair of fixed contacts. The fixed contact patterns are separated by a predetermined distance from one another. The movable contact has a first movable contact and a second movable contact for engagement with the first and the second pairs of fixed contacts, respectively. One of the first pair of fixed contacts and one of the second pair of fixed contacts are formed in a unit to define a common pattern. Only the common pattern is disposed between the other of the first pair of fixed contacts and the other of the second pair of fixed contacts.
