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.
