4 port USB response box pricing

The K-RB1-4 response box is intended for custom applications where our 1 to 8 button response pads cannot be used. Up to four high quality push-to-make/momentary buttons can be connected via 3.5mm mono jacks. We recommend high quality Piko buttons which can be purchased separately. We can also supply a range of arcade cabinet style buttons which can be mounted in your own enclosure or table top.

All response boxes ship with a USB host lead. Add a single shot TTL lead which produces a 50 ms wide 5 V TTL trigger when any button is pressed.
