We can respond to a variety of needs, from use in telecommunication to Power uses, by preparing different shapes and materials. |
|
 |
Solid Type
The solid contact typically used. |
|
|
 |
TCC Type
A composite contact modified to save costs. |
|
|
 |
Double TCC Type
A double composite contact saves costs when both sides are used. |
|
|
 |
Tubular Type
When stamping a rivet contact on a fragile base material, such as Bakelite, etc., this type is frequently used. It is available in a solid type and a TCC type. |
|
|
 |
Button Type
A contact assembled on spring material or bi-metal base by welding. |
|
|
| • |
Saving silver and increasing welding life with our unique header process. |
| • |
Excellent reliability due to the step structure of contact head. |
| • |
Perfect bonding from center to edge, in contrast to conventional types. |
 Relative Durability of HITACT Contact and Normal Contact. |
Test Conditions: AC100V-10A resistive load
Stationary contact: as above (HITACT)
Movable contact: φ2.0 × 1.1 + φ 2.8 × 1.1 R10 (solid type)
Material: E120
