Low-voltage, low-current, silent switching actuator

[macko]

Hello, usually, whenever I need a switching actuator I pick one of thousands of relay-based solutions and move forward. This time it turns out I need to place the actuator in the customer's living room and we need it to be silent. Fortunately, it will only switch on/off 24V low-current (~10mA) circuits, so I started looking for any (opto)transistor-based solutions but couldn't find any. What do you usually use for switching circuits like this? I need 4 channels but can do with two units of 2-ch solution

Thanks!

In your case a 24V heating actuator might work. Depends, if normal "On/Off" is enough or if you need additional features of a switching application.

Thanks for the answer! 24V heating actuator, 24V led dimming actuator - all those make sense, but seem overpriced (and more imporantntly - overcomplicated!) for the basic functionality of turning a circuit on and off.

In fact, I am mimicking a micro switch on the other board that doesn't have any other integration possibility, so additional logic needs to be implemented to quickly go through states 0-1-0

I will go with one of those, whichever turns out to be cheaper, thanks again!

In the past i used a couple of MDTs BE-06001.02 (available as 2, 4 and 6 IO Version) with I/Os configured as output and there connected simple optocouplers like PC814 (or similar) to have potential free outputs.
Nowadays i go for the OpenKNX SEN-UP1-8xTH what offers more options in software out of the box.
