DATA SHEET
RELAY
This is a medium to high sensitivity, circular, sealed miniature
relay of proprietary design. It is fitted with a balanced
armature system enabling it to give long and satisfactory
operation while being subjected to severe conditions of
acceleration and vibration.
The maximum springset load is eight changeovers, but
various springset combinations including make before break
actions are available.
It is only available for chassis mounting with solder
terminations.
