Clamping contact

Stamping & Assembly

This spring finds its use in fuse boxes for making reliable electrical contact. For optimal investment, springs in 8 different lengths are made with one adjustable stamping tool. Notice especially the very small slits in these springs! That is a challenge to make and maintain.

The counterpart, a tin plated brass stamped profile, in the different lengths, is also produced by KeyTec as well as the assembly of both these parts into a subassembly that our customer further assembles into a ready to market product.

Why KeyTec is succesfull in springs

Springs are used in numerous applications and in a lot of different functions, either static or dynamic. The springs we manufacture can be used just for ease of fixation, good dynamic properties (i.e. special attention edges of the springs), combination of spring function and electrical contact etc. As such our springs are used in automotive applications (i.e. LED lights, camera’s,  bezels, EMI shields etc), in medical applications (sensors) and in house and building applications (power distribution, lighting armatures).

KeyTec has extensive know how on the achievable tolerances for these stamped springs in all kinds of different materials. Especially in applications with a dynamic functionality we are able to provide options with specific requirements on part edges. We start with a close cooperation in the engineering phase with DFM and supply of prototypes. We have different ways to make these stamped springs with progression tooling, with Bihler bending machines as well as specific bending machines for really small springs.
