$25.00

By request!

The 1 Relay Switching Board is a versatile add-on board, based on our popular 3 Relay Switch Board, that has a single DPDT 5V relay (2 switch functions) and a regulated power supply all on one board. It can be powered from either a 5VAC rectifier tap or 6.3VAC filament tap (as long as the switching ground is floating and not reference to the same ground as the filament center tap).

The 1 Relay Switching Board can be used to switch any functions via 1 button footswitch and/or panel mounted toggle switch. The board also has terminals to accommodate a chassis-mounted LED. The board has a very small footprint - just 3.125in x 1.25in. Only 1in vertical height required (not including any mounting hardware).
