bauenmk202016 Apr 2022 13:32Hello,
I am currently installing the surface-mounted (access point) electrical wiring (cable routing, sockets, switches, access point boxes) in our garage so that an electrician can later connect it to the main supply line. I have installed two LED tubes which I want to control from two different locations. A momentary switch circuit will be used, meaning I have two push-buttons. Currently, I run the lamp connections with a 3x1.5 mm² (3x16 AWG) cable to a junction box. To the push-buttons, there are 5x1.5 mm² (5x16 AWG) cables each.
I now have the following options/variants:
(1) Switching relay in the junction box
(2) Switching relay in a small sub-distribution board on a DIN rail.
For 1 and 2: Either smart controllable (Shelly etc.) or "dumb."
Due to the current situation, there is no sub-distribution board in the garage yet, only a supply line from the house with 3x1.5 mm² (3x16 AWG). I can only connect a max of 2 lamps and one socket here because of the limited conductor cross-section. So, a sub-distribution board for this single line would be overkill! (Later, there will be a proper sub-distribution board with a supply line of at least 4 mm² (11 AWG)).
I would also prefer a variant with smart control, such as Shelly 1 or Shelly Pro. Without smart control, I would use a “phase pulse relay for flush mounting 8-230V 1S ES61-UC Eltako” – but basically only as an emergency solution.
Which option would you recommend and why? And which switching relays would be suitable? If a sub-distribution board is recommended, which one would be economical and appropriate, and what advantages might I gain from a small sub-distribution board?
As already mentioned, I would like to integrate the relay into my smart home system, which is implemented wirelessly (Zigbee, Shelly). As a side note: This installation will very likely operate in parallel with the proper garage sub-distribution board later on. Basically, lighting and garage door drive will be wired via the house circuit breaker, and the remaining sockets, including heavy-duty power, wallbox, etc., will be connected through the later sub-distribution board.

I immediately thought of a bistable 24V relay. A 24V power supply and low-voltage wiring to the push buttons. Easy to integrate later into any smart home system. Is it allowed to run 24V and 230V (approximately 120V) in the same junction box? Your solution would be a control cabinet with a 24V power supply mounted on a DIN rail, right?

I would use a two-way switch system. That would, of course, be the simplest and already usable solution. However, unlike in the house, I want to make the electrical installation more flexible. That would not work with a traditional two-way switch and on/off switches. Hence my choice of push buttons (Busch-Jaeger ocean rocker push buttons), which I want to connect to a relay. The relay then switches the lighting circuit.
