Simple design - will it work

Guys

I need to wire up a remote switch for a milling machine in my garage.

Rather than go into a lot of detail all I need to achieve is continuity betwenn A & B on the linked diagram but I can only use a momentary switch (SW1)

Can someone confirm if the planned circuit will work ie when SW1 is momentarilly closed then continuity will provided aacross A&B until the 12V power is switched off.

Also on a different topic, I need to connect a 10k pot to my inverter to vary the power output. Circuit diagram shows 3 connections,

1) +10V (Power terminal of Pot) 2) Analog frequency signal input terminal 3) 0VAnalog common point

Any idea how I identify which pin is which on my pot

Cheers

Jim

This circuit will not do what you want it to do. AB will be connected as long as you keep the momentary switch pushed but will disconnect when you release that switch almost immediately. To achieve your goal you need a DPST relay as shown below. (View with fixed font.)

If you have the two SPDT relay as in your drawing already available, you can use them by switching the coils in parallel.

--+------+--------------------12V | | | | | | +-----+ | | | | +---- A | | | | | | | | | | o\\ o o\\ o X_|_ Y_|_ | \\ x \\ y |_/_|- |_/_|- | \\. \\. | | | o o | | | | | +------+-----+ | +---- B | | | | | o | |=|> | | o | | | | | -+------------------+------------- created by Andy´s ASCII-Circuit v1.24.140803 Beta

As for your pot, you'd connect the pin in the middle to connection 2. The 1 and 3 connection come on both outside pins. You can exchange when required.

Jim Inscribed thus:

Yes the relay will work fine !

For this, more info is needed !

Rectification: The schematic of the OP will work the same way the second schematic above does. It's drawn in a (to me) unusual way but electrically the same except that +12V and GND are exchanged.
