Relay re-activating

  1. Mar 17, 2010 #1
    Hey guys,

    I am using the following circuit to switch on/off another circuit.


    The problem is that for some reason the relay will disengage about a minute after it is switched on (although it seems to remain off indefinitely).

    Does anyone have any ideas for what could be causing this?

    100 uF charges to 6 volt.

    When switch is pressed, 100 uF discharges to 1.83 volt.
