    latching pushbutton help

    I checked and there are about 3.6V, can I use this selector? I post also the photos of the PWM control

    latching pushbutton help

    I forgot to attach S4 to the positive side of the circuit I know but 4 relay are cheaper than a selector rated for that current

    latching pushbutton help

    First of all I apologize for the horrible PWM Control. I try to explain the circuit: S5:main switch (I chose a DPDT Switch becouse it's cheaper than a SPDT/SPST switch and then I can use the other contacts to connect some LEDs) S1:4 posn rotary for set the speed of the motor S4: (same as S5) It...

    latching pushbutton help

    hahaha, It's written in Italian Can I use directly a 4 posn rotary or I need to use relays to control the resistances? What types of resistors should I use?

    latching pushbutton help

    I've already bough a PWM control and I already have a 4 posn rotary. What power supply should I buy if I use this motor? http://it.rs-online.com/web/p/motoriduttori-cc/4095232/

    Can I add a delay in some other way?

    I think it is so low that it is not relevant

    latching pushbutton help

    I understood this but if I press the button opens the negative part of the circuit and the coil never get energized http://it.rs-online.com/web/p/motoriduttori-cc/4095232/ this isn't good?

    latching pushbutton help

    I tried. however, I did not fully understand the circuit. I also tried to simulate it but I can't make it work. First things first: L1 corresponds to + and L2 to -?

    latching pushbutton help

    I remade the schematic, I hope that this time is more understandable. I drew only 2 relay because I have no time but the concept is this. I forgot to specify that those are bistable relay

    http://it.rs-online.com/web/p/motoriduttori-cc/4095232/ I found this, I think is more suitable

    latching pushbutton help

    Yes I know but it's expensive The motor drives a crank-connecting rod mechanism

    latching pushbutton help

    No need to be precise, if i need too adjust the speed I can use a potentiometer instead of the resistors

    latching pushbutton help

    ok, I want to use this motor, it is possible to slow down to 50 RPM? http://it.rs-online.com/web/p/motori-cc/2483671/

    latching pushbutton help

    I can't find anything on the internet about this type of control However, I think I'll open another thread specific for the motor but I think something like that would be fine http://it.rs-online.com/web/p/motori-cc/2483671/ it's a program to simulate circuits However, is my scheme wrong?

    latching pushbutton help

    Actually I didn't understand everything I forgot to ask,is there a monostable relay in multisim 11? can't find it

    latching pushbutton help

    I want also reverse the motor but I know how to do that part of the circuit. I tried to draw a scheme but it's probably wrong I use the second NO contact of the buttons to send an impulse to the activated relay but I don't know how the relay that i'm trying to activate might react

    latching pushbutton help

    I think I confused the meaning of "latching" with "bistable". However I don't understand how to use the NC contacts for what I have to do

    latching pushbutton help

    Currently I don't know, I have an AC drill motor (500w) but I would buy a DC motor (24V) but I don't now if it's possible to slow down the motor to 50-200RPM (the range of the 4 buttons) Are you talking about latching relay or monostable relay?

    latching pushbutton help

    Hi everyone, I want to control a motor via four buttons, each button would run the motor at a predetermined speed. By pressing one of four buttons the engine starts, but I don't know how to detach the relay (supposedly) by pressing another button to change the speed of the motor. I tried to...
