Relay type 4-way, RCA unbalanced audio signal selection, audio source input switching (actual 2-4 steps adjustable)
The use of 2mm thick double-sided gold-plated PCB, giving the most direct and most fidelity switching of audio sources, the board is stereo dual-channel.
Iron handle switch version: the switch is four-speed switching (the switch is always twisted three times, that is, four-speed).
Plastic handle switch version: the switch has a card hole to adjust the gear, can be 2 or 3 or 4 gear switching.
If your chassis has 2 groups of inputs, the switch is adjusted to 2-position adjustable (the switch can only be screwed once).
If your chassis has 3 groups of inputs, the switch is adjustable to 3 positions (the switch can only be twisted twice).
If your chassis has 4 inputs, set the switch to 4-position adjustable (the switch can only be twisted three times).
Otherwise, when only 3 inputs are used, but the switch is 4-position adjustable, one position is empty.
Similarly, when only 2 groups of inputs are used, but the switch is 4-position adjustable, two positions are empty.
The advantage of the plastic handle switch is that you can select the number of gears, which can be suitable for different chassis input signal groups, more convenient for you to install.
Supply voltage single group AC12-15V, can also choose DC12-18V input. If you need AC7-9V power supply can also be, please specify before purchase.
4 Relay unbalanced version (WZ-15) size: switch board 46mmx49mm, main board 46mmx107mm.
Maximum height is approx. 20mm for easy mounting into a low profile chassis or above the original PCB.
Plastic handle mounting holes of about 10mm, iron handle mounting holes of about 9mm.
This board circuit is very simple, see the board to understand, so we no longer provide wiring diagrams, only provide component list.
Buy PCB friends to the component number mounted on the normal work, non-wiring diagrams can not be friends please do not buy.
Can be switched to 4 groups of signal inputs, and has a LED light tube for gear switching instructions.
