On the
Relay Diagrams there are four entries for "Constant to Momentary Output" relay setups
But the Text is the same for all four, and is the proper text for just the +/+ one.
The capacitor allows the coil of the relay to be energized until the capacitor stores a charge, thus de-energizing the coil. The resistor bleeds off the charge of the capacitor when positive voltage is removed from the other side of the coil. You can increase the output time by simply changing the value of the capacitor. This one will give you about a 1/2 second output.
Example
Its the same for circuits that should say things like "The resistor bleeds off the charge of the capacitor when the
Negative Switch is allowed to float (disconnected)" for the +/- one.
I'm posting in relays, because I didn't see a
Problems or
Website Issues one.
Good catch and thanks for posting! The text needs to be updated for the negative switched relays (-/- and -/+). All four diagrams were drawn, but not labeled with the coils being connected to a switched 12V source and not a constant 12V source, however a constant 12V source can be used for the negative switched diagrams and the capacitors will discharge when ground is removed (by the switch) as the resistor is connected to both capacitor terminals.
