摘要 | A reed contact is formed from sheet metal by means of a punching operation. The end of the contact is designed so that any burrs resulting from the punching extend away from the contact surface into a kerf-shaped recess. | ||||||
权利要求 | 1. A device for manufacturing a reed contact comprising a cutting plate and a guide adapted to receive and hold an essentially flat reed having a narrow part, a cutting punch for cutting a reed, said cutting plate and said guide each including a nose portion for engaging and clamping a narrow part of a reed, said cutting punch upon being lowered separating a reed into a contact part and a discardable part along a line through the narrow part of the reed, and said cutting punch pushing any burrs into the narrow part of the reed out of the way of a contact face of the reed to reduce the risk of making contact between the burrs and similar reed contacts. 2. A device as claimed in claim 1 in which the narrow point is formed by a kerf-shaped recess on each side of the reed, and any burrs formed by action of the cutting punch are formed in one of the kerf-shaped recesses where no electrical contact will be made by the burrs with other reed contacts. |
