RH Series Relays & Sockets

RH Series Compact Power Relays
Switches & Pilot Lights Compact power type relays
SPDT through 4PDT, 10A contacts

The RH series are miniature power relays with a large capacity. The RH relays feature
10A contact capacity as large as the RR series but in a miniature package. The compact
size saves space.
