A SP3T slide switch (single pole triple throw) may be used. It may be identified by a higher pitch between one terminal and common. Should SP3T not be available DP3T may be used.


Here's a way you can do it with a single pole ON-OFF-ON switch. simulate this circuit – Schematic created using CircuitLab It relies on the center 'OFF' position LED D1 needing more voltage to turn it on than the others. When either of the 'ON' LEDs is switched in its lower voltage drop robs current from the 'OFF' LED. D4 increases the voltage ...


@Jasen has a very simple way of doing it that is probably what you should use. Just for interest, here is a circuit that (at the cost of a few more parts) uses less power because it does not depend on shorting out an LED in two of the positions, so it's better suited for battery power. simulate this circuit – Schematic created using CircuitLab


Here's one way to do it using an ON-OFF-ON switch like this one: one half of the switch in either on position shunts D3 preventing it from illuminating, this wastes about 20mA in the off position the LED lights the other half selects between the other two LEDs when on simulate this circuit – Schematic created using CircuitLab


I am going to add this one because someone mentioned bistable relays. If anyone wants to make it really easy on themselves for just a few more dollars, you can use this module. The relay is self latching and only needs a negative trigger. V+ Connect positive voltage S1 Set1 is your negative voltage from Limit Switch 1 R1 Reset1 is your negative voltage from ...


I know this post is 6 year old but, I hope this helps you in some way or at very least helps others who see it and need it? The circuit is actually very simple but hard to explain. Using a 3PDT (Triple Pole Double Throw) relay, Wire the first two poles as if it were a DPDT reversing relay. Connect Positive Power to the relay coil. The negative of the coil ...
