Title:
OPTICAL EQUIPMENT
Document Type and Number:
Japanese Patent JPH02198404
Kind Code:
A
Abstract:
PURPOSE:To reduce the contact resistance, and also, to lower the possibility of the separation of both which follows up the movement of a contact by connecting the contact and a conductive member whose electric resistance is small to the contact of a movable side where the low contact resistance is requested, so that turning the contact is suppressed. CONSTITUTION:A contact supported so as to be freely movable in the contact direction is connected directly to a linear or band-like conductive member with an adhesive material such as solder so that the conduction to a circuit can be obtained, and also, it is provided against a supporting member so that the contact cannot turn. In such a manner, when a connecting member such as a lead wire is used in order to reduce the contact resistance of a movable contact, an optical equipment which prevents the separation of the movable contact and the connecting member and makes the contact part compact can be obtained.
