2 questions about Pushbutton Power Switch LV:
I need to power the device by motion. When someone picks it up it should power on. I am planning to use tiny mercury switch ( I know they are not safe ). Will the Pushbutton Power Switch LV reliably turn on? There will be a lot of bouncing in mercury switch. I have read something about connecting
one side of the button to ground and the other side to the switch pad that is closer to the edge of the board. Will this eliminate bouncing problem?
Also in another application I need to power a device by a logic level (3.3V) pulse coming from another device with the common ground. Can control push button be replaced with a signal? Do I need to add a trans to amplify current? Can you provide schematic so I can understand it better?
I will be using OFF input to power off device apter period of inactivity. At this time mercury switch will be calm an off. So I do not want the control push button to switch device off. I just want to confirm that the control push button can be connected between GND and the pin closet to the edge? Also if power is on, does constant triggering of the mercury switch affect it?
Yes, the modification described should make the circuit capable of only turning on from the mercury switch.
Thank you for reply.
Another question: After I put device down it is possible that it will be in a position where mercury covers the switch contacts. What happens if OFF signal comes when contacts are closed? Will it still power of the device?
If the mercury switch is in the on position, you will not be able to turn off the circuit.
