Mechanical Delay Device

Out of a high current-50 amp-relay rack likely used to control large motors. This device, actuated by the gray bar at lower left, introduced an adjustable delay of approximately one second after the solenoid is powered up. This is a pneumatic device with a knob, top rear, to change the rate at which air escapes. The motion controls a switch, top left. We have six of the large three-phase relays.
