Abstract
The present invention provides a contact mechanism which comprises a fixed contact and a movable contact. The fixed contact is formed by arranging two terminals having a plurality of parallel contacts so that the contacts are disposed in an alternating manner and at a predetermined pattern pitch. The movable contact is disposed above the contacts of the fixed contact to be able to connect with the contacts of the fixed contact. The pattern pitch of the contacts is set within a range of 0.4 mm to 0.8 mm. The present invention provides a durable contact mechanism having stable output levels.
