Abstract
A multiple remote control VCR pause switch is provided which allows any number of viewers to pause an accessory video cassette recorder to, for example, answer questions posed on the video tape. Each viewer is provided with a response switch mounted inside a cabinet. A valid first response lamp and an invalid response lamp are provided on a switch console for each response switch. The first viewer to activate his response switch pauses the VCR and causes his valid first response lamp to illuminate. Subsequent activation of any of the remaining response switches has no effect and the invalid response lamps for those response switches stay illuminated. A reset switch is provided and the rewind search may be remotely controlled.
