Series 115 – Mini-V-SIL up to 1 A, 20 W

1 Form A (SPST) or 2 Form A (DPST) N.O. relays – SPST stacks on 0.15 ” x 0.27 ” pitch. 3, 5 or 12 V coils. Featuring sputtered ruthenium contacts for long life and high reliability.

Two switch types available – switch type 1 is better suited for general purpose applications. It has a layer of copper beneath the ruthenium to help dissipate the heat from the contact area. This gives an improved current inrush handling ability. Switch type number 2 should be chosen for low level or ‘cold’ switching applications.
