So been given a task to make a control board to turn on/off water pump and heat exchanger with one switch.
Could anyone give me a light on this?
Switch picture below and info https://uk.rs-online.com/web/p/piezo-switches/6919575/
what parts will i need?
mcb`s, relays, contactors timers etc? must be din mountable.
And would be nice if someone made a little drawing aswell.
motor is 10A
heater is 40A

 

Is this for a business, school homework or personal ?
It is a SPST Momentary Switch - with three color LEDS.
Can you draw a simple schematic?

We are running electrical firm, and one customer gave us this momentary pulse switch and said i want to turn on/off jakuzzi water pump and heater with it...

switch is : NO prolongated pulse (ground connector compulsory)

 

motor is 10A
heater is 40A

How about their voltages?

 

How about their voltages?

motor and heater 220AC

 

That switch is only rated for 24v.
If you want to make a custom one DIN mountable then Weidmuller have blank circuit boards to populate with the DIN mount frame.
What is the object of requiring only one switch?
I have a monostable relay circuit for one PB. you would need a 24vdc supply and suitable contactors for pump and heater.
Max.

 

What I thought just like below:
1. A small ac to dc 12V Adaptor to provides the power for CD4017 and two relays.

2. A push button and a switch debounce circuit and a CD4017 to make a counter divided by 3, the control sequences like this, CD4017 0,1,2. (0 -- All Off, 1 -- Motor On, 2 -- Heater On, repeatedly)

3. 2 small signal N-MOSFET to drive two 12V relays.

4. Use two of this relays. (100A/120A High power magnetic latching relay-coil voltage DC 12V)

5. The circuit just like above number sequences of 2,3,4.

 

The one I have just used two relays and a couple of components.
.The basic circuit RLA would be used to pick up contactors etc, reverts to off in power down situation.
Max.
